Hi James,

HTTPService has a contentType property that can be set to
HTTPService.CONTENT_TYPE_XML or HTTPService.CONTENT_TYPE_FORM. If you
specify CONTENT_TYPE_FORM (the default) the 'request' that you send
needs to be an anonymous Object. The name/value pairs in the Object will
be application/x-www-form-urlencoded into the body of a POST.

If you specify CONTENT_TYPE_XML the 'request' really should be XML. If
you use this content type but pass an anonymous Object, an attempt is
made at serializing it to XML but I'd recommend generating the XML
yourself because the automatic Object serialization isn't XML Schema
aware.

If you set 'request' to be a typed AS class instance, in the
CONTENT_TYPE_FORM scenario if your type was 'dynamic', any enumerable
key/value pairs would be encoded into the POST but that's it. If the
type isn't dynamic, it has no enumerable name/value pairs so the request
body ends up empty. If you used CONTENT_TYPE_XML your instance would be
wrapped as XML but not in the way you'd want. So the moral of the story
is to stick with anonymous Objects or XML for the 'request' based on the
'contentType' you're using.

To wrap up, here's why a request may be sent as a GET versus a POST (or
vice versa), when you've explicitly asked for the other via the 'method'
property:
1. If you set the 'method' to GET but use CONTENT_TYPE_XML, the
assumption is that you want that data sent and a POST is used because an
XML payload can't be sent on the URL.
2. If you set the 'method' to POST but pass an empty 'request' (by using
CONTENT_TYPE_FORM with a non-dynamic typed instance as your 'request')
the underlying flash.net.URLLoader switches the method to GET
automatically. This is core player behavior, and I've logged a bug
asking that the user-assigned 'method' always be respected even if it
results in a POST with an empty body.

I hope that helps explain the current behavior.
Best,
Seth

Hey all, 
I am using the ActionScript HTTPService and I found an issue with it.
I feel its a bug, but I may have been "misusing" the functionality
and I got away with it until I pushed too far. Here is the
problem/issue:

I have a JSP app that I am calling via HTTP that returns XML data. 
One of the services requires that the data comes in via POST and not
GET. No biggie, just set the method propert... or so I thought.

When I called the app it kept coming back with "" and after looking at
the HTTP headers we realized it was always coming in as a GET even
though I explicitly set it to POST. This is where things started to
get odd... some of my service calls (all routed through the same
service code) came out as POSTs and some as GETs.

I was able to track down the cause and it was all based around the
format of the object that I was passing to the request property. For
example, if I did it this way my call became a POST (as desired)

myService.request = {zip: "94103};

If I created a custom VO class that had public properties that matched
the required parameters it converts to GET on the call(protocode):

class MyZipVO
{
public var zip:String = "94103";
}



var temp:MyZipVO = new MyZipVO();
myService.request = temp;

I didn't catch this at first because my previous services worked as
either GET or POST but once I tried to access the one that required
POST it all blew up. Anyway, I figured it out and I can work around
it, but any idea on why this fails or if this should work in the first
place?

James

RE: [flexcoders] Re: Choice of backend systems - which provides best functionality

2006-08-23 Thread Franck de Bruijn

Hi Darren,

I developed my webservices such that you
have to supply a security token in the header section of a SOAP operation. By
using a security token you prevent needing to send the user credentials over the
line every time for every request to the back-end. It’s a mechanism used
heavily in most web-based systems (including single sign-on). Maybe the
difference is that often these security tokens are sent in by means of cookies.
Webservices don’t need cookies; they have a header section (something
that simple HTTP requests/posts don’t).

After a successful login operation, a
security token is generated and stored in the database together with the
necessary user profile information. So, the user session information is
actually stored in the database and not in the application server. Yes, you
have to do an extra query to your database to get the session information back,
but since it’s a very simple and fast query on a primary key it will take
be nearly costless.

Databases are around now for more than 20
years. They have been totally optimized for data storage and data distribution
(if you need a clustered database). It’s my belief that databases can do
this much better than application servers (or myself/yourself). 

I also try to rule out caching (of dynamic
data) in my application servers. Each normal thinking human being understands
that caching (and the distribution of the cache among your application server
cluster) introduces many headaches. In my experience, when performance issues
arise, most often these are solved by writing cleverer queries, rearchitecting
your interface, and even maybe take some consequences in the UI (ok, we
don’t display that attribute directly, but behind a tab or something). In
my opinion caching is rarely the best solution for performance increase, but
probably the easiest to develop ... and the hardest to maintain.

Cheers,

Franck

Flex inherits the HTTP session that the page which contained the EMBED

yet we can easily secure those. The theory is identical with Flex.

RE: [Junk E-Mail - LOW] [flexcoders] Re: Choice of backend systems - which provides

2006-08-23 Thread Franck de Bruijn













Hi Ted,

 

We all understand your arguments 1 and 2.
But in the end, and that’s already identified in this topic, it’s
the user experience that counts. If it does not suffer by using web services,
it’s not an issue! I’d like to hear the first story that changing
webservices by AMF increased the user experience significantly and sealed a
certain business proposition.

 

For argument 3 ‘Developer
Productivity’ it’s true that developers need to program more lines
of code to obtain the same result (having your webservice result as an
ActionScript object), which is, I admit, error prone. But in the total view of
the costs of a development project ... it will not make much of a difference.
The actual additional lines of code I’m talking about, however, are very
easy to generate from a model if you wish.

 

Again, FDS is cool, really true and it
does have its place. But for many applications FDS (including the extra
features messaging and data management) is neither an option nor necessary.

 

Cheers,

Franck

AMF is
faster in 3 fundamental ways:

 


 Bandwidth Size – Smaller, lighter,
 faster!!!


 


 Parsing Speed – Less work on both client
 and server!!!


 


 Developer Productivity – Less work for
 developers!!!


 

Web Services
are dependent on XML Parsing on both the client and server side. Although
it’s a good story, XML parsers are not very efficient as parsing
documents is an interpreted process. The Flash Player XML parser will always be
dramatically slower than AMF parsing, binary formats are notoriously faster in
this regard. 

 

XML
parsing additionally decays rapidly as the file size increases. Flash Player
XML parsing time increase non-linearly with larger XML documents. With AMF
parsing times are linear with data size. The XML decay can be attributed to the
number of inner objects that need to be created during a parsing run. AMF
objects are 1:1 with the data received where XML data is 1:N per
Elements/Attribute.

 

Comparing
XML to AMF is an unfair race, AMF wins every time. When you add in the overhead
of WS SOAP parsing atop the base XML parser speed you begin to see performance
issues. With SOAP, you interpret an XML document back into typed objects
depending on the SOAP specifics used. Sure 350ms is ok once or twice, but try
doing 200 transactions in this format and you will see performance issues
arise. Using Web Services you are forcing the Flash Player to do allot of
unneeded work. The goal is to build richer applications, not burn up player
performance in crud operations.

 

Additionally
non-proxied Web Service use suffers with Flash Player because of the browser
variation in the plug-in APIS. You cannot get the 500 Errors response content in
IE and thus the SOAP fault standard breaks down. In SOAP there are important
messages that arrive with 500 Errors and the inability of the Flash Player to
receive these is a problem. Unfortunately there is no seamless way to get 500
Errors into the Flash Player other then rewriting an HTTP Client in the Socket
class. This effort would also require a new SOAP library within Flex and socket
use on low ports requires a more complex crossdomain.xml configuration.
Even then you still suffer the same performance issues.

 

Performance
aside, the productivity discussion is much more important. AMF3 and Flex Data
Services are wildly productive. Once you compile your Java Class and configure
a destination in FDS (1 XML Element), you are done. All typing is handled, All
methods are ready to run with any number of client applications. It is the
easiest way to create a server side API that I know of. Actually most cases,
implementing FDS will removes $20,000 of developer time wasted on implementing
other data exchange for an application. FDS value is easy to see when viewed
through this productivity ROI metric. If you add CF integration into FDS, you
enjoy an even more productive jump. We spend so much time talking about
performance but we often waste so much developer time doing mundane data
exchange when things could be automated.

 

Having
worked at Cynergy Systems, everyone needs to realize that Carson, Dave and Team
are industry leading professionals at Web Services. They know SOAP better than
any single consulting firm that I know of. These guys were on teams at Sybase
and Microsoft building the first generation of Web Services integration servers
(MS BizTalk, EAServer)!!! They have the expertise to make Web Services/JAVA
work seamlessly with Flex but this is out of reach for most (unless you hire
them). They can jump through flaming hoops that few developers can with the
FLEX / TOMCAT / AXIS / JAVA stack. They have been down a very hard ro

Hello
All,

I have a Form with several fields - and those fields are all bound to a

After doing my database calls, etc., my Form populates beautifully with
all the values. However, if I edit any of those fields on the Form, and
then send the same ValueObject back to the server, nothing is changed -
it's as if I didn't make any changes to the Form itself.

It was my understanding, that once a Binding Relationship is created,
that any changes (either in the Model itself, or the Fields that are
tied to the Model) will update in both directions.

Is this not true, or am I missing something?

Thanks all for your help,

RE: [flexcoders] AS HTTPService ignoring method propety













Ah, I believe HTTPService does a for..in
loop over the parameters, and if you use a strongly typed class the for..in won’t
return anything.  Then when you try to send no parameters to a POST request it
will be turned into a GET by the Player.

 

We should make sure that’s mentioned
in the docs (or look into changing that behavior…).

RE: [flexcoders] FlexBuilder 2.0 SDK plugin with IBM RAD 6.0?













Yeah, RAD 6.0 is based on Eclipse 3.0.2, I
believe they are updating in their next release.  We will be working with them
to try to make things compatible.  So for now you do need two versions of
Eclipse.  Sorry!

Has anyone tried to install the plugin to RAD 6.0?
When I try it tells
me "wrong eclipse version". It looks like my RAD eclipse version is
3.0.2, but RAD 6.0 is IBM's latest and greatest. Maybe someone could
tell me how to install it successfully? Am I gonna have to run two
versions of eclipse? : |

Thanks,
Libby

class PendingCall



 







Hi All,
Actually m migrating my application from flex1.5 to flex 2 :
In Flex 1.5 the code was somewat like this:
generated\service\BulkCrudService.mxml(56): Warning: variable
'__call' 
has no type declaration.
var __call /*: PendingCall*/ ;
This variable we are using in service files,just to store how many 
pending calls are there.

In flex 2 ,this code is giving me a warning as now variable should 
have its type.
So as per the code in flex 1.5 the class mx.remoting.PendingCall; is 
nto there in flex 2 ,so what should i use instead of PendingCall class.

If anyone has any idea ,plz reply.

RE: [flexcoders] RTE in List when filtering ArrayCollection













OK, we’ve filed a bug on this and

Matt,

the filter is removing Items indeed, to solve the problem , I set the verticalScrollPosition
to 0 before applying the refresh() method. 
To have it assigned to a single dataProvider , it's not a problem to use this
kind of workaround but I think this should be handle by the listclass.

were earlier?  That'd be a bug in the list class, it should be able to
handle the reduction.  Maybe you can detach the dataProvider, filter it,
and then re-assign it?

Hi everyone,

 

I'm having this error

When applying a refresh() on an

Any Ideas?

[flexcoders] Don't bindings work both ways??

2006-08-23 Thread Mike Anderson

Hello All,

I have a Form with several fields - and those fields are all bound to a
ValueObject (using the Curly Braces method).

After doing my database calls, etc., my Form populates beautifully with
all the values.  However, if I edit any of those fields on the Form, and
then send the same ValueObject back to the server, nothing is changed -
it's as if I didn't make any changes to the Form itself.

It was my understanding, that once a Binding Relationship is created,
that any changes (either in the Model itself, or the Fields that are
tied to the Model) will update in both directions.

Is this not true, or am I missing something?

Thanks all for your help,

Mike

[flexcoders] Re: Remote object help again..

2006-08-23 Thread Mark Piller

Hey Jeff,

This is very helpful. I didn't know about the
"trace(ServerConfig.xml)" trick. Would it make sense to add some
special logic to the compiler to validate all destinations in the
code? That would need to apply to all mx:RemoteObject declarations as
well as ro.destination = "xxx" type of assignments.

Cheers,
Mark

Re: [flexcoders] Adobe, Help Memory Leaking !!

2006-08-23 Thread Joshua Garnett




Have you tried setting the recycleChildren attribute of the Repeater to false?  I believe when you have recycleChildren set to true, even if you reduce the number of items in the dataProvider, it still keeps an object in memory that it will reuse.  I've actually encountered other issues with having recycleChildren set to true when the repeaters are nested within repeaters.  There doesn't seem to be any noticeable performance hit by switching it to false.

I have been able to get the sample app over 200 megs of ram usage by runnig 5000 buttons a few times, the app memory in the txt box shows about 185 megs  See the attached screen shots.  The 5000 was created 1st and then I updated the array to 5 buttons and waited and then took the 2nd screen shot.  The browser never releases the memory and neither does the flash player.

Rich,

 

No. I have yet to run this app and see 300MB of RAM
consumed ever.  Mine gets a ceiling of like 12MB and never goes higher.

 

When the GC runs it destroys objects within the
totalMemory within the player. When the player needs more memory for new
objects, it adds memory if the gc cannot dispose of what is needed. It is true
to say that on machines with ample resources, the player may accumulate more
resources but this is true with all applications.

 

I have to say I think you may be looking at a bug specific
to your os/system configuration. Is the behavior browser specific? 

 

Just to be sure: 300 megabytes = 314,572,800 bytes

I first noticed this issue while looking at the task
manager and seeing firefox and IE memory usage going up and up to well over 300
megs of ram.  If I am running the app on a machine with less ram will the
browser use less memory?  Is that what you are saying?

Rich,

 

Ok
got some information for you:

 

flash.system.System.totalMemory
- The amount of memory (in bytes) currently in use by Adobe®
Flash® Player.

 

A
better way to think about this is allocated memory. When the player needs more
memory it acquires it from the OS/Browser in use. The player doesn't
necessarily give the memory back. Within that memory in use are the objects
being used. When GC runs, it disposes objects within the allocated memory but
doesn't give memory back to the OS/Browser.

 

The
GC is running and collecting objects, but f lash.system.System.totalMemory
is not the right way to see this happening.

I am testing locally on a pentium m 1.6 2 gigs ram FP
9.16
I have tried firefox, and ie on winxp

On my sample, if you change the number to like 500 and create 500 buttons and then
change it back to 3 buttons, why can I not recover the memory from the 497
buttons that are no longer being used? 

This is a huge probolem on my app because it has like 30 Repeaters that are
constantly changing dataProviders on user decisions and the memory is out of
control, eventually crashing the browser (remember I have 2 gigs of ram).

[flexcoders] Tree & Datagrid highlight color bug?

2006-08-23 Thread Jeff Kroll






Hi 
All,
I developed an 
application that's essentially a property sheet with a tree and dataGrid in it 
and it works just fine. Specifically, when I roll over a tree item or row in the 
dataGrid , color of the background automatically changes to the nice default 
"highlight" blue.
 
Later I decide I 
want to have this property sheet application pop up by clicking on a button in a 
launcher app, so I build the launcher app and change the property sheet 
application so it can be launched (replace Application with titleWindow, etc... 
very easy).
 
Now when I launch 
the property sheet, the background color of the selected and rolled over tree 
items and dataGrid rows are black, and the text color is super dark 
gray!!!
 
What gives? Is this 
a known bug and is there a work around?
 
By the way, I'm not 
using any Style sheet or Style declarations. It's all very vanilla code, and 
everything else about the popped up property sheet works as before. It's just 
the highlight color that's wonky.
 
Cheers,Jeff

Yes I have had the same problem with all the applications that I have
created.  Not sure if bad coding on my part or bug in the plugin. 
Hope this problem gets fixed soon!

[flexcoders] AS HTTPService ignoring method propety

2006-08-23 Thread James Polanco

Hey all, 
I am using the ActionScript HTTPService and I found an issue with it.
I  feel its a bug, but I may have been "misusing" the functionality
and I got away with it until I pushed too far.  Here is the problem/issue:

I have a JSP app that I am calling via HTTP that returns XML data. 
One of the services requires that the data comes in via POST and not
GET.  No biggie, just set the method propert... or so I thought.

When I called the app it kept coming back with "" and after looking at
the HTTP headers we realized it was always coming in as a GET even
though I explicitly set it to POST.  This is where things started to
get odd... some of my service calls (all routed through the same
service code) came out as POSTs and some as GETs.

I was able to track down the cause and it was all based around the
format of the object that I was passing to the request property.  For
example, if I did it this way my call became a POST (as desired)

myService.request = {zip: "94103};


If I created a custom VO class that had public properties that matched
the required parameters it converts to GET on the call(protocode):

class MyZipVO
{
 public var zip:String = "94103";
}



var temp:MyZipVO = new MyZipVO();
myService.request = temp;

I didn't catch this at first because my previous services worked as
either GET or POST but once I tried to access the one that required
POST it all blew up.  Anyway, I figured it out and I can work around
it, but any idea on why this fails or if this should work in the first
place?

James

RE: [flexcoders] Variable Type for Web Service Result

Ethan,

I don't think it's your typing, I think it's your timing.  Looks like you're 
flipping your postTyper() when the combobox is changed, but that's not 
firing a new send() like the original blogger example did.  Try changing 
your code so that changing the combobox triggers the send() and the send 
result="" handler triggers the postTyper().  That way you'll have the 
correct data in lastResult when you change your blogResult variable.  That 
change should then be noticed by the bindings.

[flexcoders] Re: FDS + Hibernate exception committing updates

2006-08-23 Thread thunderstumpgesatwork

Hi Jeff,

I am not using the version or timestamp features of hibernate, however
I am using the cascade="all" feature to manage sets of child objects
off of the main managed object. In fact, it is this collection of
child objects that has changed (removed one, added one, etc.)

Should the "transitive persistence" work correctly using cascade="all"
? Could this be part of the cause of the conflict?

Also, setting NONE has
fixed the conflict issue, and with it the closed session exception.

If you were to send me those fixes, how difficult would it be for me
to encorporate them into my version of FDS? Do I need to build the
entire project? I have not done so before, but if needed, and I should
have all the source necessary, I'm comfortable attempting it.

thanks,
Thunder

Re: [flexcoders] Need help identifying which Event to listen for

2006-08-23 Thread Jeremy Lu

When selection changes, you can access current selected child via ViewStack.selectedChild, which points to the currently selected child container, you can then trigger a method inside the child to re-grab the data. see if this works for you :-)

RE: [flexcoders] FDS + Hibernate exception committing updates

2006-08-23 Thread Jeff Vroom













Are you using either the “version”
or “timestamp” features of hibernate?   This causes improper
conflicts to be detected in the GMC version (though we have fixed this already
in house).  To workaround that problem, you can turn off conflict detection:

 

   
NONE

 

in your destination’s 
tag.   If that is not a suitable workaround, let me know.   We
distribute the HibernateAssembler source so I could send you a version with the
fix in it.

 

I may also see the problem with the lazy
initialization exception… there is code in the hibernate assembler which
goes through and does a “deep fetch” of all properties which are
not lazy=”true” associations in FDS’s configuration.  Hibernate
by default has all of its properties marked with its own setting of lazy=”true”
which means that those properties are not fetched when the parent object is
fetched.  Since we need to serialize the state of all non-lazy properties
and do not want to keep the hibernate session open for this process, we do this
deep fetch ahead of time to be sure the state will be available for sending to
the client.  Unfortunately, when we are throwing a DataSyncException for
the conflict we are not doing the fetch of the object properties for the “serverVersion”
of the object which also gets sent back to the client.  If my theory is
correct, this error will go away when the conflict goes away but of course it
still needs to be fixed.   I just made this fix locally so I could
send that along as well.  

 

Jeff

Hi all,

I have loaded a collection of managed objects, made some changes to
one of them, and called the DataService.commit() to commit these
changes back to the database.

My DataService is connected to a HibernateAssembler destination, and
this destination worked to create the initial version of the objects,
however when I attempt to update them, I get this exception. I can
tell there was a data sync conflict (not sure why, I'm only using one
client, one session, one update to the object). However what concerns
me more is that it's attempting to do something afterwards, and I get
this Hibernate exception about the session being closed. Any ideas?

[flexcoders] Re: Cairngorm 2 - Web Service event handlers

2006-08-23 Thread ben.clinkinbeard

I've been using this method ever since I started with Cairngorm.
http://www.darronschall.com/weblog/archives/000234.cfm

It makes a lot of sense and just feels more natural to me to have the
commands handle the results and faults since they are the ones
requesting the calls anyway.

Subject: [flexcoders] Similar Node
Access Question



 







Don't know if this is the same problem as my recent,
previous post, or if 
it's different, but I basically have the same question...

Now I'm calling a CF WebService that returns a Query object... it just 
contains one row, one column, called FULLNAME.

Using the WebService lastResult in a DataGrid's dataprovider works fine, 
there's a million examples of that, but trying to pull out that FULLNAME 
cell's string value is proving to be a challenge for me...

8"?>

xmlns:mx="http://www.adobe.com/2006/mxml"
creationComplete="IACleanService.authenticateUser.send()">


wsdl="http://localhost/ia_cleanup.cfc?wsdl">


jsmith
asdf1234





dataProvider="{IACleanService.authenticateUser.lastResult}"
/>


text="{IACleanService.authenticateUser.lastResult.fullname}"
/>



The DataGrid above displays the FULLNAME field just fine, but the TextArea 
displays nothing. Doesn't help to uppercase it to lastResult.FULLNAME 
either.

I'm probably missing something really simple, but... just about all the 
examples in the Flex documentation either show how to pull out a single node 
value from an HTTPService... or show how to use a WebService in a 
DataGrid... but I can't find any examples where single values are pulled out 
of a WebService result. Something where the result node values are split up 
and used in different places, like one node value is used as a role 
variable, another is used to set a model state variable, another is used as 
a button label, etc. I need an example of calling a WebService and breaking 
the result into pieces for use in multiple places, not just sticking the 
whole lastResult into the dreaded DataGrid. Any help would be appreciated 
:-)

Thanks!
Darren

RE: [flexcoders] Project References vs. ActionScript Build Path

Thanks Martin; this is good information. It sounds like the JDT has a good
solution, although I wouldn't mind seeing behavior similar to Visual Studio
where referenced projects are built and then added to the bin directory of the
referencing project. I recently read a thread here talking about how to handle
multiple swf/swc projects and I hope to see further discussion on these topics
in the future.

Thanks again for your insight,

RE: [flexcoders] How to cast a WebService lastResult when CFC returnType="xml"

2006-08-23 Thread Tracy Spratt













Darren,

You are using a tree according to the
example in  your post.  Or have you changed your question?

 

At any rate, binding is very difficult to
debug.  I advise using a handler function in which you can use toXMLString() on
the event.result object.

 

Then work your way down through the
hierarchy a step at a time.

 

When you get the _expression_ that works you
can put it in the binding _expression_.

 

Tracy

Peter,

Thanks! But I'm not using the results in a Tree or Grid, which seem to have 
some magical parsing happening inside for you. I just want to do something 
as simple as pulling a node value out of the incoming SOAP wrapped XML and 
using it in, say, a TextArea. But... the following doesn't work...


text="{MyService.myOperation.lastResult.people.person.firstname}"
/>

nor does

MyService.myOperation.lastResult.people.person[0].firstname
MyService.myOperation.lastResult.person.firstname
MyService.myOperation.lastResult.person[0].firstname

or any other pattern I've tried. Amy suggested referencing the path all the 
way from the root node of the SOAP packet itself and treating the entire 
SOAP message as a bix XML result, instead of just the node path of the 
result. Something like...

MyService.myOperation.lastResult.myOperationResult.people.person.firstname

but I couldn't get that to work either.

2006-08-23 Thread Tracy Spratt













Yes, use a server-side proxy to return the
data in response to a HTTPService post request.

 

Though to be honest, I am not absolutely certain
that this data is not cached somehow.

RE: [flexcoders] Similar Node Access Question

Hey, answered my own quetion... figured I'd post it here in case it helped 
anyone else...

So... you're using an  to call a ColdFusion CFC.  The 
ColdFusion query object returned in lastResult is an array inside an array, 
but, it's more than that too (the debugger is your friend) so... the easiest 
way to grab a specific value from specific row in a query is to refer to the 
query row by array notation and the column by name... so... to grab the 
FULLNAME column from row 1 of your query object's result set you'd use...

var mystr : String = MyWebService.myOperation.lastResult[0].FULLNAME;

and if you wanted to bind to that purely in mxml you could also use...

[flexcoders] FDS + Hibernate exception committing updates

2006-08-23 Thread Thunder Stumpges

Hi all,

I have loaded a collection of managed objects, made some changes to
one of them, and called the DataService.commit() to commit these
changes back to the database.

My DataService is connected to a HibernateAssembler destination, and
this destination worked to create the initial version of the objects,
however when I attempt to update them, I get this exception. I can
tell there was a data sync conflict (not sure why, I'm only using one
client, one session, one update to the object). However what concerns
me more is that  it's attempting to do something afterwards, and I get
this Hibernate exception about the session being closed. Any ideas?
thanks in advance,
Thunder

When the GC runs it destroys objects within the
totalMemory within the player. When the player needs more memory for new
objects, it adds memory if the gc cannot dispose of what is needed. It is true
to say that on machines with ample resources, the player may accumulate more
resources but this is true with all applications.

 

I have to say I think you may be looking at a bug specific
to your os/system configuration. Is the behavior browser specific?

How you found any kind of resolution?  As it stand right now my application will be unusable by most of my audience which will obviously not make management happy.  I haven't had this problem with other apps, but there were not nearly as object and data intense.

doesn't give memory back to the OS/Browser.

 

The
GC is running and collecting objects, but f lash.system.System.totalMemory
is not the right way to see this happening.

This is a huge probolem on my app because it has like 30 Repeaters that are

2006-08-23 Thread Jeff Vroom

I have not heard of this caching bug
before, but I’ll follow up and see Flex Builder is doing any caching that
might cause this.  

It is the case that when you compile your
SWF, the compiler needs to have a pointer to your services-config.xml
file.  It includes a subset of the destination configuration into the SWF.
 You can see what it has included when you enable debug logging on the
client (e.g. via: ), or you can just trace it out via:

import mx.messaging.config.ServerConfig;

….

 trace(ServerConfig.xml);

When I’ve seen this problem in the
past, it was due to the fact that the compiler’s configuration did not
include a pointer to the correct services-config.xml.

Did you add your destination after your Flex Builder
project was
created? We hear about this problem quite often. It appears Flex
Builder caches remoting-config.xml and does not fetch the file every
time you build the project. As a result, if a destination is added
after the project is created, it will not be recognized unless you do
one of the following:

- restart Flex Builder
- open project properties window, select the 'Flex Compiler' section
and click 'Apply'

It would be very helpful to get a confirmation from Adobe for this bug.

Re: [flexcoders] Re: custom component: how to tap into resize?




> 
When components you are creating, framework you will want to use, no?I don't know if I understand exactly what you are asking but, if it is "When I create components that are .as files and subclass a framework class, do I want to use the Template Method Pattern of the flex framework?"
The answer would be yes of course.I would put it this way.If you are developing a car and you are an engineer, you would use the schematics of the car design, the way the car was engineered to run to add a specific add in subsystem in the internal workings of the car.
Now, If I was an outside company that created addd-ons for that car, I would use the 'macro' schematic verses the micro of the actual car engineering.The thought is, the tighter you integrate your design into the frame of the target, the tighter your component becomes and actually becomes PART of the car not an addon.
If I was creating an mxml component, I would tend you use events more because in my view, an mxml component is an addon not an inherent subsystem of the framework.I don't advocate creating anything in mxml that needs to be subclassed in the future because although it gets rendered into an as3 class, it is not extensible like an as3 class file because the development pattern differs in respect to creating a subsystem of the actual framework.
Anyway, rambling aside, events belong to clients. The framework belongs to subsystems of that framework. If you have a composite component(client of the component) inside your subclassed as file, by all means use events. Just don't use events in a component to talk to itself.
Performance wise, this pattern will always beat events.Peace, MikeOn 8/23/06, tddclare <[EMAIL PROTECTED]

RE: [flexcoders] Flash Data Services - help needed

Hi Benjamin,

With regard to the exception, in your services-config.xml file you'll can find 
a  for an RTMP channel. The RTMP channel endpoint on the 
server is a socket server that binds to the port specified in the  element. A single port can't be bound by multiple handlers, so if 
you have several FDS applications running on your Tomcat server you'll need to 
configure the RTMP channels across these applications to use unique ports.

Hope that helps,
Seth

Hi everyone,
 
finally i found the time to try out the data services. I`m using tomcat 5.5 and 
Java Open Transaction Manager form my basic setup.
I was able to run the samples that ship with fds but now when i try to set up 
my own projects i get stuck with some errors.
I get the following message from the tomcat logs:
 
Exception in thread "RTMP-Server" flex.messaging.endpoints.rtmp.RTMPException: 
The RTMP server has encountered a fatal exception starting up: Address already 
in use: bind

Let me say i`m not a server or java guy - so if anyone has an idea.
It would also be good if someone could point me to a basic tutorial for setting 
up fds and building a simple application - not based on the samples that ship 
with fds. 
For me it would be important to know how to configure the various configuration 
xml files in the flex folder. 
 
Thanx for any help

No. I have yet to run this app and see 300MB of RAM
consumed ever.  Mine gets a ceiling of like 12MB and never goes higher.

 

When the GC runs it destroys objects within the
totalMemory within the player. When the player needs more memory for new
objects, it adds memory if the gc cannot dispose of what is needed. It is true
to say that on machines with ample resources, the player may accumulate more
resources but this is true with all applications.

 

I have to say I think you may be looking at a bug specific
to your os/system configuration. Is the behavior browser specific? 

 

Just to be sure: 300 megabytes = 314,572,800 bytes

A

memory it acquires it from the OS/Browser in use. The player doesn't

Does anyone know how to get the garbage collection to run when the

[flexcoders] Variable Type for Web Service Result

2006-08-23 Thread Ethan Miller

Greetings -

Expanding on the "Connecting to Web Services" tutorial, I added a  
combo box for switching between methods of the API to the Adobe blog  
aggregator, ie from getMostPopularPosts to search.

As both methods return the same columns, the data grid displaying the  
result can stay the same, other than needing a different value for  
data provider, ie:

myWebService.getMostPopularPosts.lastResult
vs
myWebService.search.lastResult

I was hoping therefore to bind the dataGrid dataProvider value to a  
variable which I'd set when users change the value of the comboBox  
(which selects which method to use). However I think I'm typing the  
variable which stores the value of the service result wrong, as I get  
null whenever I try and set the value (blogResult), show below:

Re: [Junk E-Mail - LOW] [flexcoders] Re: Choice of backend systems - which provides

2006-08-23 Thread James Ward

-BEGIN PGP SIGNED MESSAGE-
Hash: SHA1

A few things...

First I am working on a demo that will show the performance and
bandwidth differences between the various ways of exchanging data
between Flex apps and the backend.  I'll let everyone know when it's
ready...  Hopefully next week.

Second, the GZIP thing does work to reduce bandwidth, but you take quite
a hit on latency and server cpu cycles depending on just how much data
and how often stuff is passing through the servlet or apache filter.

In every case I've ever seen, RemoteObject significantly increases
developer productivity, significantly reduces bandwidth, significantly
reduces latency, significantly reduces server load, and significantly
reduces client cpu cycles.  This applies to REST, SOAP, and JSON.  With
the most significant benefits when compared against SOAP, since SOAP is
so verbose compared to the others.

[flexcoders] FlexBuilder 2.0 SDK plugin with IBM RAD 6.0?

2006-08-23 Thread Libby

Has anyone tried to install the plugin to RAD 6.0? When I try it tells
me "wrong eclipse version". It looks like my RAD eclipse version is
3.0.2, but RAD 6.0 is IBM's latest and greatest. Maybe someone could
tell me how to install it successfully? Am I gonna have to run two
versions of eclipse? : |

Thanks,
Libby

Re: [flexcoders] Re: How to refresh a tree




Hi,There is some issues with the Tree and XML dtat provider collections.One thing I can suggest is;Add an event listener to the divider bar release, I can't remeber what it is, in that handler call
myTree.invalidateList();Give it a try and let me know.I have the same issues with using itemRenderers and changing some internal data specific things. After I am done with my process, I called invalidateList() and it did a nice redraw quickly.
There probably is just an update isse and measure() is not being called correctly.Peace, MikeOn 8/23/06, e baggg <

[flexcoders] Re: Functionality Between Components and the Main Application

2006-08-23 Thread tddclare

i completely agree with Jeff - using the events is the best way to go.

If, for some reason that doesn't work for you, you can always reference the 
application 
using mx.core.Application.application, which is a reference to the top top 
Application 
(even if your swf is loaded inside another application's swf.

You can also traverse the parent application(s) for nested apps with any 
component's 
parentApplication property:

Re: [flexcoders] Flex / Coldfusion / Combobox / Retrieve selected data value

How about cvcompanyValue.selectedItem.data

I can easily return the selected label in the combobox using:

RE: [flexcoders] Adobe, Help Memory Leaking !!













Rich,

 

No. I have yet to run this app and see 300MB of RAM
consumed ever.  Mine gets a ceiling of like 12MB and never goes higher.

 

When the GC runs it destroys objects within the
totalMemory within the player. When the player needs more memory for new
objects, it adds memory if the gc cannot dispose of what is needed. It is true
to say that on machines with ample resources, the player may accumulate more
resources but this is true with all applications.

 

I have to say I think you may be looking at a bug specific
to your os/system configuration. Is the behavior browser specific? 

 

Just to be sure: 300 megabytes = 314,572,800 bytes

I first noticed this issue while looking at the task

megs of ram.  If I am running the app on a machine with less ram will the
browser use less memory?  Is that what you are saying?

Rich,

 

Ok
got some information for you:

 

flash.system.System.totalMemory
- The amount of memory (in bytes) currently in use by Adobe®
Flash® Player.

 

A
better way to think about this is allocated memory. When the player needs more
memory it acquires it from the OS/Browser in use. The player doesn't
necessarily give the memory back. Within that memory in use are the objects
being used. When GC runs, it disposes objects within the allocated memory but
doesn't give memory back to the OS/Browser.

 

The
GC is running and collecting objects, but f lash.system.System.totalMemory
is not the right way to see this happening.

On my sample, if you change the number to like 500 and create 500 buttons and then

buttons that are no longer being used? 

This is a huge probolem on my app because it has like 30 Repeaters that are

I have an

dataproviders are constantly updated which redraws the view. All look
fine visually, however the flash player continues to use more and more
memory.

I created a demo version of this at
http://www.everythingflex.com/flex2/MemoryTest/

I have buttons which up the amount of repeater items and then lower
them and also attemp to delete the arraycollection, delete the
dataprovider, etc but the memory never is recaptured.

The source is also provided.

Does anyone know how to get the garbage collection to run when the
repeaters content changes??

[flexcoders] custom component: how to tap into resize?

2006-08-23 Thread tddclare

I'm creating a custom component extending UIComponent.

Much of the component is drawn by the Drawing API during the updateDisplayList 
using 
settings calculated during the commitProperties.  Works great.

The problem arises when the end developer USING the component changes the size 
of it 
manually (example: the height and width are 150, and they create a button whose 
click 
changes the component's width to 300).

My commitProps and updateDispList are VERY conditional - only redrawing the 
elements that 
NEED to be redraws to increase performance.  

What I can't find / missed is how to know the component itself resized and to 
set a flag that 
will tell my commitProps and updateDispList to redraw everything.  What is that 
event / how 
do I tell they resized me?

Thanks!

[flexcoders] Extending a subclass of Proxy

2006-08-23 Thread Danny Patterson






I'm trying to extend 
a subclass of the Proxy class and I'm getting an error.  Here is an example 
of my problem:
 
// ProxyA.as
package 
{  import flash.utils.Proxy; import 
flash.utils.flash_proxy;
 
 public class 
ProxyA extends Proxy {flash_proxy override 
function callProperty(methodName:*, ...args):* {   return 
"ProxyA: " + 
methodName;  }   } }
 
 
// ProxyB.as
package 
{  import flash.utils.flash_proxy;
 
 public class 
ProxyB extends ProxyA {flash_proxy override 
function callProperty(methodName:*, ...args):* {   return 
"ProxyB: " + 
methodName;  }   } }
 
 
// 
ProxyBugExample.as
package 
{  import flash.display.Sprite; import 
flash.utils.Proxy;
 
 public class 
ProxyBugExample extends Sprite {public function 
ProxyBugExample() {   var proxy:Proxy = new 
ProxyB();   trace(proxy.test());  }   } }
 
I the ProxyB class I 
get the following error:
Namespace was not 
found or is not a compile-time constant.
 
I assume this is 
referring to the flash_proxy namespace, but it is imported just like in the 
ProxyA class.  I'm not sure what the problem here is, any help would be 
appreciated.
 
Thanks,
Danny

[flexcoders] Flash Data Services - help needed

2006-08-23 Thread Benjamin Dobler











Hi everyone,

 

finally i found the time to try out the data services. I`m
using tomcat 5.5 and Java Open Transaction Manager form my basic setup.

I was able to run the samples that ship with fds but now
when i try to set up my own projects i get stuck with some errors.

I get the following message from the tomcat logs:

 

Exception in thread
"RTMP-Server" flex.messaging.endpoints.rtmp.RTMPException: The RTMP
server has encountered a fatal exception starting up: Address already in use:
bind

    at
flex.messaging.endpoints.rtmp.BaseNIORTMPServer.run(BaseNIORTMPServer.java:310)

    at java.lang.Thread.run(Unknown
Source)

 

Let me say i`m not a server or java guy – so if anyone
has an idea.

It would also be good if someone could point me to a basic
tutorial for setting up fds and building a simple application – not based
on the samples that ship with fds. 
For me it would be important to know how to configure the various configuration
xml files in the flex folder. 

 

Thanx for any help

 

Benz

[flexcoders] Re: Choice of backend systems - which provides best functionality

Darren,

Flex inherits the HTTP session that the page which contained the EMBED
tag acquired.  Dont forget that HTTP/HTML is entirely stateless and
yet we can easily secure those.  The theory is identical with Flex.

[flexcoders] Flex / Coldfusion / Combobox / Retrieve selected data value

2006-08-23 Thread michrx7

Ok, so I've created a combo box with id cvcompanyValue, then I call my 
coldfusion cfc and return a query with two fields "data" and "label". 
Data holding a list of company IDs and label holding the corresponding 
company names. Then I set the combobox provider to the result and 
everything populates as it should.

I can easily return the selected label in the combobox using:

Alert.show(cvcompanyValue.selectedLabel.valueOf());

But, how do I return the data of the selected combobox (my original 
IDs)? Do I have to sort through the ArrayCollection until I find the 
matching label? I can't imagine there isn't something like:

Alert.show(cvcompanyValue.selectedData.valueOf());

Help please!

RE: [flexcoders] Re: Disabling a nested menu item in a menu bar?

2006-08-23 Thread Deepa Subramaniam

Hi Jeff –

MenuBar.getMenuAt() returns a reference to
a Menu. getMenuAt() is a method on MenuBar and menuItems is a property on
MenuBar, which is why you encounter the errors below when you try to use those
APIs on a Menu. 

Since Menus are dynamically created as
needed, there is a possibility a nested child menu has not been created yet. As
menus get created, MenuBar adds those menus to its ‘menus’ array. ‘menus’
is a handy array that stores Menus created for that MenuBar control and you
might find that handy for your needs. 

If you can’t guarantee that the
menus have been created but you still want to walk your MenuBar, you can go at
it from a data-centric point of view. You can use the MenuBar’s
dataDescriptor to walk the MenuBar’s data looking for children
(hasChildren(), getChildren() will be handy) at each node. If children exist,
you know that node has a sub-menu. 

One last thing – it looks like your
original question was how to disable menu items. Since disabling/enabling is a
data-driven functionality (all you need to do is toggle the enabled property)
you can do it through the data bound to the MenuBar instead of walking the
MenuBar’s individual Menus and sub-Menus. For example, you can use e4x to
access the node you want to disable in the MenuBar dataProvider and set the
enabled attribute to false and boom, your MenuBar will show that menu item as
disabled without any extra work. Or, you can go at it through your MenuBar’s
dataDescriptor and find the node you want to disable and use
IMenuDataDescriptor.setEnabled() to disable that node. 

HTH –

deepa

Sadly, thats where the problems started for me. I'm
able to get at 
the top level items, using getMenuAt or even using the menuItems 
array, but sadly, i cant seem to get a handle on the first child menu

var myMenu:MenuBar = myMenuBar;
var nextLevel:* = myMenu.getMenuAt(0);

// throws error Property menuItems not found on mx.controls.Menu
var firstNestedChild:* = nextLevel.menuItems;

// throws error (Property getMenuAt not found on mx.controls.Menu)
var firstNestedChild:* = nextLevel.getMenuAt(0);

so, coming back to the original question, what syntax can i use to 
get a handle on the nested children MenuBarItems?

RE: [flexcoders] Re: Webservice Destination with Basic Authentication

Hi,

Have you verified that the server hosting your web service has basic auth 
configured correctly? Your code looks correct so perhaps when the FDS proxy 
makes the call against the remote server it isn't being challenged for basic 
auth credentials? Try requesting your WSDL in a browser and verify that the 
browser's challenge box pops up.

Best,
Seth

Re: [flexcoders] Adobe, Help Memory Leaking !!




I first noticed this issue while looking at the task manager and seeing firefox and IE memory usage going up and up to well over 300 megs of ram.  If I am running the app on a machine with less ram will the browser use less memory?  Is that what you are saying?  
RichOn 8/23/06, Ted Patrick <[EMAIL PROTECTED]> wrote:



















Rich,

 

Ok got some information for you:

 

flash.system.System.totalMemory - The
amount of memory (in bytes) currently in use by Adobe® Flash®
Player.

 

A better way to think about this is allocated memory. When
the player needs more memory it acquires it from the OS/Browser in use. The
player doesn't necessarily give the memory back. Within that memory in
use are the objects being used. When GC runs, it disposes objects within the
allocated memory but doesn't give memory back to the OS/Browser.

 

The GC is running and collecting objects, but f
lash.system.System.totalMemory
is not the right way to see this happening.

I am testing locally on a pentium m 1.6 2 gigs ram FP

I have tried firefox, and ie on winxp

On my sample, if you change the number to like 500 and create 500 buttons and
then change it back to 3 buttons, why can I not recover the memory from the 497
buttons that are no longer being used? 

This is a huge probolem on my app because it has like 30 Repeaters that are
constantly changing dataProviders on user decisions and the memory is out of
control, eventually crashing the browser (remember I have 2 gigs of ram).

The app takes memory up 7MB then drops back to 5Mb on a GC

I have an

dataproviders are constantly updated which redraws the view. All look
fine visually, however the flash player continues to use more and more
memory.

I created a demo version of this at
http://www.everythingflex.com/flex2/MemoryTest/

I have buttons which up the amount of repeater items and then lower
them and also attemp to delete the arraycollection, delete the
dataprovider, etc but the memory never is recaptured.

The source is also provided.

Does anyone know how to get the garbage collection to run when the
repeaters content changes??

RE: [flexcoders] Adobe, Help Memory Leaking !!













Rich,

 

Ok got some information for you:

 

flash.system.System.totalMemory - The
amount of memory (in bytes) currently in use by Adobe® Flash®
Player.

 

A better way to think about this is allocated memory. When
the player needs more memory it acquires it from the OS/Browser in use. The
player doesn’t necessarily give the memory back. Within that memory in
use are the objects being used. When GC runs, it disposes objects within the
allocated memory but doesn’t give memory back to the OS/Browser.

 

The GC is running and collecting objects, but flash.system.System.totalMemory
is not the right way to see this happening.

I am testing locally on a pentium m 1.6 2 gigs ram FP
9.16
I have tried firefox, and ie on winxp

On my sample, if you change the number to like 500 and create 500 buttons and
then change it back to 3 buttons, why can I not recover the memory from the 497
buttons that are no longer being used? 

This is a huge probolem on my app because it has like 30 Repeaters that are
constantly changing dataProviders on user decisions and the memory is out of
control, eventually crashing the browser (remember I have 2 gigs of ram).

The app takes memory up 7MB then drops back to 5Mb on a GC
run. There is no way to force the GC to run.

 

Can you also send me your browser, os, player version. Also
are you on a dual-core machine?

I have an
application that uses many repeaters where the repeater's
dataproviders are constantly updated which redraws the view. All look
fine visually, however the flash player continues to use more and more
memory.

I created a demo version of this at
http://www.everythingflex.com/flex2/MemoryTest/

I have buttons which up the amount of repeater items and then lower
them and also attemp to delete the arraycollection, delete the
dataprovider, etc but the memory never is recaptured.

The source is also provided.

Does anyone know how to get the garbage collection to run when the
repeaters content changes??

[flexcoders] recurse tree and set selectedNode

2006-08-23 Thread kengaree

Hello,
I am trying to reset the selectedNode property on the tree control
after I have changed a value in the dataProvider
with this retrieveNode() function...
private function retrieveNode(theNode):TreeNode{
  for(var index in theNode.getChildNodes()){
var node:TreeNode = TreeNode(theNode.getChildNodes()[index]);
if(node.getData().periodID == view.txtPeriodID.text){   
  return theNode.getTreeNodeAt(index);
}
retrieveNode(node);
  }
}

view.treeCalendar.selectedNode =
retrieveNode(view.treeCalendar.dataProvider);

why won't the treeCalendar.selectedNode property accept this value?
But this getTreeNode() function will work?

private function getTreeNode() {
  if (view.txtPeriodID.text != null) {
var node:TreeNode =
TreeNode(view.treeCalendar.dataProvider.getChildNodes()[0]);
while (node != null) {
  if(node.getData().periodID == view.txtPeriodID.text){ 
return node;
  }
  node = TreeNode(node.getChildNodes()[0]);
}
  }
  return null;
}

RE: [flexcoders] FDS, VOs, and ignoring client-side properties

Hi Jim,

Try tagging the properties that you don't want managed in your [Managed] AS 
class as [Transient]. This should prevent changes to them from being 
logged/committed.

Seth

Subject: Re: [flexcoders] FDS, VOs, and ignoring client-side properties

Again, thanks for the suggestions. I've tried manually implementing the 
IManaged interface and using a custom event name (per your suggestions), and I 
can't seem to get bindings to work on my unmanaged property. 

I've posted a simple test app at: 
http://www.phlod.com/TestBinding/TestBinding.html
and the source code is available at:
http://www.phlod.com/TestBinding/srcview/ 

According to what you're saying, this should work right? Unfortunately as you 
see, bindings don't work for the "checked" property. Am I doing something wrong?

As I mentioned before, if I manually implement the "propertyChange" event or 
allow Flex to generate it, then the code above works as expected. However, in 
our app, the DataStore then recognizes a change in the Managed ProjectTypeVO 
object ... which is exactly what we *don't* want. 

Also, our corporation has a support contract with Adobe for Flex. Is this an 
issue we should take up there? Or will they just redirect us back to you? Let 
me know, and thanks for all your help!

Jim

2006/8/22, Jeff Vroom <[EMAIL PROTECTED]>:
I think the problem is that currently when you specify [Managed] on a class, we 
will do code-generation for all properties of the class, even those properties 
which explicitly specify the [Bindable(event="someEvent")] metadata tag on 
them.   (If your class specifies [Bindable], we do skip code-gen for the 
property if it has a per-property metadata tag though).  There is a bug opened 
on this and I think we'll fix it soon.  In the meantime, probably the only 
option is to take out the [Managed] tag which would require you to add the 
managed code yourself to that class.  For the properties you want to FDS to 
ignore, just do not fire the PropertyChangedEvent.

Hmm, if you can send us a smaller example we can look but I believe that the

of events that aren't "propertyChanged" the managed stuff shouldn't notice.

I tried doing exactly that (dispatching the custom event in my setter) when 
using implicit getters/setters for my unmanagedProp ... but for some reason the 
bindings didn't work. However, if I use a propertyChange event (either 
dispatching it myself or letting Flex generate it), the bindings seems to work 
fine. However, as I said, in this case it still doesn't accomplish what I want 
( i.e. having the DataStore ignore that property). Even if I could make the 
bindings with with my custom binding event, I'm not sure it would accomplish 
what I want.

Jim
2006/8/17, Matt Chotin < [EMAIL PROTECTED] >:
If you do [Bindable(event="unmanaged")] it is your responsibility to dispatch 
the unmanaged event.  If you just do [Bindable] it will dispatch the 
propertyChange event which will case management to notice.
 
So write a getter/setter with [Bindable(event="unmanagedPropChange")] and then 
in the setter dispatch that event.

Thanks for the idea, Matt. Unfortunately, it doesn't seem to work. I
forgot to mention that my unmanaged property needs to be bindable, and
it seems that enabling binding on this property causes the DataStore
to keep track of the property just like all the managed properties.

Curiously, binding on the unmanaged property only works when I don't
use a custom event name. Simply saying [Bindable] on the unmanaged
property causes the binding to work as it should (but also causes
the unmanaged property to become managed). Saying
[Bindable(event="someEvent")] causes the property to be treated as
unmanaged ... but also causes binding not to work. I also tried using
implicit getters/setters on the unmanaged property with similar
results.

Below is code similar to the code I used. Let me know

Franck,

I agree with you, but... how do you handle security in a stateless back-end? 
  I mean... how do you maintain logged-in / user session information?  Or 
unauthorized access of the web services by others?  If Flex is *completely* 
agnostic of the back-end technology then how do you securely link them 
together?

[flexcoders] Embedded SWF as backgroundImage causing mouseOut event to dispatch

2006-08-23 Thread Brendan Meutzner




Hi All,I've created a container which contains a couple of sub-containers that have SWF symbols set to the backgroundImage.  Problem is occurring when I set a mouseOver/mouseOut on the parent container, having the backgroundImages causes the mouseOut to get fired on the parent container.  Any solutions to prevent this from happening?
Example :[Embed(source='/assets/swf/elements.swf', symbol='flag_start')][Bindable] private var flag_start:Class;
    //This container will cause the parent to dispatch the mouseOut event because of the backgroundImage    // remove the backgroundImage and it doesn't happen         
Thanks in advance,Brendan

[flexcoders] Re: Remote object help again..

2006-08-23 Thread Mark Piller

Did you add your destination after your Flex Builder project was
created? We hear about this problem quite often. It appears Flex
Builder caches remoting-config.xml and does not fetch the file every
time you build the project. As a result, if a destination is added
after the project is created, it will not be recognized unless you do
one of the following:

- restart Flex Builder
- open project properties window, select the 'Flex Compiler' section
and click 'Apply'

It would be very helpful to get a confirmation from Adobe for this bug.

Thanks,
Mark

[flexcoders] Cairngorm 2 - Web Service event handlers

2006-08-23 Thread jakana1566

I have a cairngorm 2 app that uses multiple delegates to call 
different methods of a single web service.  The problem is, each 
delegate adds it's own "onResult" and "onFault" events, so that when 
the web service operation is called, *ALL* of the onResult functions 
are called instead of just the one associated with the calling 
delegate.

For example, one delegate has the following code:

this.service = ServiceLocator.getInstance().getService
("sym_security_standard") as WebService;

service.addEventListener(ResultEvent.RESULT, 
sym_security_sp_login_search_onResult);

service.addEventListener(FaultEvent.FAULT, 
sym_security_sp_login_search_onFault);


Another delegate has the following (similar) code:

this.service = ServiceLocator.getInstance().getService
("sym_security_standard") as WebService;

service.addEventListener(ResultEvent.RESULT, 
sym_security_sp_group_search_onResult);

service.addEventListener(FaultEvent.FAULT, 
sym_security_sp_group_search_onFault);



Since there's only one instance of the ServiceLocator, each delegate 
is registering onResult / onFault events to the *same* object 
instance, and therefore the onResult event triggers the onResult 
function of multiple delegates instead of the single/target delegate.

Any ideas on how to avoid this?

Thanks in advance!

Subject: [flexcoders] Functionality Between Components and the Main
Application


Hi! I've been trying to figure out how to do this sort of thing, and
thought I'd ask before messing with it anymore.

I have a toolbar that's in its own component, and it has some buttons on
it that will open new windows/popups. What I need to have happen is,
when one of the buttons gets clicked, the window pops up inside a
container that's on the main application. Right now they show up at the
top corner of the toolbar.

I gave the VBox in the middle of the main application an ID, but when I
try to tell the toolbar to open the window there, it gives me an error
because that ID doesn't exist inside the toolbar...

I've also tried telling the button to run a function in the main
application to open the popup but it tells me that I'm "calling a
possibly undefined method through a reference with static type Class".

I hope that makes sense. Any ideas?

Thank you!

Re: [flexcoders] Adobe, Help Memory Leaking !!




I am testing locally on a pentium m 1.6 2 gigs ram FP 9.16I have tried firefox, and ie on winxpOn my sample, if you change the number to like 500 and create 500 buttons and then change it back to 3 buttons, why can I not recover the memory from the 497 buttons that are no longer being used?
This is a huge probolem on my app because it has like 30 Repeaters that are constantly changing dataProviders on user decisions and the memory is out of control, eventually crashing the browser (remember I have 2 gigs of ram).

Rich,

 

The app takes memory up 7MB then drops
back to 5Mb on a GC run. There is no way to force the GC to run.

 

Can you also send me your browser, os,
player version. Also are you on a dual-core machine?

Memory Leaking !!



 







I have an
application that uses many repeaters where the repeater's
dataproviders are constantly updated which redraws the view. All look
fine visually, however the flash player continues to use more and more
memory.

I created a demo version of this at
http://www.everythingflex.com/flex2/MemoryTest/

I have buttons which up the amount of repeater items and then lower
them and also attemp to delete the arraycollection, delete the
dataprovider, etc but the memory never is recaptured.

The source is also provided.

Does anyone know how to get the garbage collection to run when the
repeaters content changes??

Re: [flexcoders] FDS, VOs, and ignoring client-side properties

2006-08-23 Thread Jim Laing




Again, thanks for the suggestions. I've tried manually implementing the IManaged interface and using a custom event name (per your suggestions), and I can't seem to get bindings to work on my unmanaged property. I've posted a simple test app at:
http://www.phlod.com/TestBinding/TestBinding.htmland the source code is available at:http://www.phlod.com/TestBinding/srcview/
According to what you're saying, this should work right? Unfortunately as you see, bindings don't work for the "checked" property. Am I doing something wrong?As I mentioned before, if I manually implement the "propertyChange" event or allow Flex to generate it, then the code above works as expected. However, in our app, the DataStore then recognizes a change in the Managed ProjectTypeVO object ... which is exactly what we *don't* want.
Also, our corporation has a support contract with Adobe for Flex. Is this an issue we should take up there? Or will they just redirect us back to you? Let me know, and thanks for all your help!Jim
2006/8/22, Jeff Vroom <[EMAIL PROTECTED]>:



















I think the problem is that currently when
you specify [Managed] on a class, we will do code-generation for all properties
of the class, even those properties which explicitly specify the [Bindable(event="someEvent")]
metadata tag on them.   (If your class specifies [Bindable], we do skip
code-gen for the property if it has a per-property metadata tag though).  There
is a bug opened on this and I think we'll fix it soon.  In the meantime,
probably the only option is to take out the [Managed] tag which would require
you to add the managed code yourself to that class.  For the properties you
want to FDS to ignore, just do not fire the PropertyChangedEvent.

Hmm, if you can send us a smaller example we can look but I believe
that the approach that I mentioned should work.  If you have bindings that
fire because of events that aren't "propertyChanged" the
managed stuff shouldn't notice.

I tried
doing exactly that (dispatching the custom event in my setter) when using implicit
getters/setters for my unmanagedProp ... but for some reason the bindings
didn't work. However, if I use a propertyChange event (either dispatching it
myself or letting Flex generate it), the bindings seems to work fine. However,
as I said, in this case it still doesn't accomplish what I want ( i.e. having
the DataStore ignore that property). Even if I could make the bindings with
with my custom binding event, I'm not sure it would accomplish what I want.

2006/8/17, Matt Chotin < [EMAIL PROTECTED]

If you do [Bindable(event="unmanaged")]
it is your responsibility to dispatch the unmanaged event.  If you just do
[Bindable] it will dispatch the propertyChange event which will case management
to notice.

 

So write a getter/setter with [Bindable(event="unmanagedPropChange")]
and then in the setter dispatch that event.

Thanks
for the idea, Matt. Unfortunately, it doesn't seem to work. I
forgot to mention that my unmanaged property needs to be bindable, and
it seems that enabling binding on this property causes the DataStore
to keep track of the property just like all the managed properties.

Curiously, binding on the unmanaged property only works when I don't
use a custom event name. Simply saying [Bindable] on the unmanaged
property causes the binding to work as it should (but also causes
the unmanaged property to become managed). Saying
[Bindable(event="someEvent")] causes the property to be treated as
unmanaged ... but also causes binding not to work. I also tried using
implicit getters/setters on the unmanaged property with similar
results.

Below is code similar to the code I used. Let me know if I'm doing
something wrong. And thanks for the suggestion!

[flexcoders] Flex 2 History Manager Oddities

2006-08-23 Thread Battershall, Jeff

I set up a virutal server in Apache (on my laptop) for my FB project
using the address dev.djindexes.com, and set up that as a local address
in my hosts file, and as a local address in IE.

When I run my project - it runs in the address - great. However, when I
try implementing HistoryManager, I get a security sandbox error saying
that the LOC running in domain djindexes cannot access domain
dev.djindexes.com.  

I deciced to try creating a new virtual domain starting with www instead
- now it works fine.  Seems I can re-create the behavior using any
subdomain other than www - is this a bug? Or is there a known way to get
the History Manager Lc to work with subdomains?

[flexcoders] Remote object help again..

2006-08-23 Thread Jeremy Rottman

I am working on a simple application that uses remote objects to pass
data to and from my db. But I keep running into the same problem.

In my services-config.xml file, I have setup the destination ROTEST. It
looks like this


 
 
 
 
 beta.cfc.ROtest
 
 
 
 false
 

remote
 

 
 
 false
 

false
 

false
 
 
 


I wrote this simple flex application to test my connectivity.


http://www.adobe.com/2006/mxml";
layout="absolute">







http://beta.homesmartagent.com/flex2gateway/";
showBusyCursor="true"
fault="qryService_userSearch_Fault(event)"/>











 



Everytime I test the application, I get this error.
faultCode:Server.Processing faultString:'No destination 'ROTEST' exists
in service flex.messaging.services.RemotingService' faultDetail:'null'

I know my destination exists in my services-config.xml file, but for
some reason it can not find it. I have set the channel correctly in my
services-config.xml file as well.
  
 
 http://beta.homesmartagent.com/flex2gateway/";
class="flex.messaging.endpoints.AMFEndpoint"/>
 
 false
 
 false
 
 
 
 

Can someone shed some light on this for me.

Hi 

This email is for Benoit Hediard: 

You submitted an issue saying that an MP3 that has ID encoded with iTunes
doesn't play in flash player. 


I tried reproducing with itunes 6.0.5.20 , but it played just fine.
 

We also knew about an iTunes bug where the ID3 is encoded 
incorrectly, however my understanding was that the bug was fixed, 
which is the reason I couldn't repro with 6.0.5.20. So I closed out 
the issue when you first submitted it in the beta phase. 


Recently, you submitted this issue again, saying that you repro'ed 
with 6.0.5.20. I have not been able to repro. 


Can you please provide me the .mp3 file that you can't run in flash 
player 9? 


You ddin't leave your e-mail address, so this is why I'm sending out 
a blanket one to flexcoders yahoo group. 


Thanks,

[flexcoders] Similar Node Access Question

Don't know if this is the same problem as my recent, previous post, or if 
it's different, but I basically have the same question...

Now I'm calling a CF WebService that returns a Query object... it just 
contains one row, one column, called FULLNAME.

Using the WebService lastResult in a DataGrid's dataprovider works fine, 
there's a million examples of that, but trying to pull out that FULLNAME 
cell's string value is proving to be a challenge for me...


http://www.adobe.com/2006/mxml";
creationComplete="IACleanService.authenticateUser.send()">

http://localhost/ia_cleanup.cfc?wsdl";>


jsmith
asdf1234










The DataGrid above displays the FULLNAME field just fine, but the TextArea 
displays nothing.  Doesn't help to uppercase it to lastResult.FULLNAME 
either.

I'm probably missing something really simple, but... just about all the 
examples in the Flex documentation either show how to pull out a single node 
value from an HTTPService... or show how to use a WebService in a 
DataGrid... but I can't find any examples where single values are pulled out 
of a WebService result.  Something where the result node values are split up 
and used in different places, like one node value is used as a role 
variable, another is used to set a model state variable, another is used as 
a button label, etc.  I need an example of calling a WebService and breaking 
the result into pieces for use in multiple places, not just sticking the 
whole lastResult into the dreaded DataGrid.  Any help would be appreciated 
:-)

Thanks!
Darren

RE: [flexcoders] How to cast a WebService lastResult when CFC returnType="xml"

Peter,

Thanks!  But I'm not using the results in a Tree or Grid, which seem to have 
some magical parsing happening inside for you.  I just want to do something 
as simple as pulling a node value out of the incoming SOAP wrapped XML and 
using it in, say, a TextArea.  But... the following doesn't work...



nor does

MyService.myOperation.lastResult.people.person[0].firstname
MyService.myOperation.lastResult.person.firstname
MyService.myOperation.lastResult.person[0].firstname

or any other pattern I've tried.  Amy suggested referencing the path all the 
way from the root node of the SOAP packet itself and treating the entire 
SOAP message as a bix XML result, instead of just the node path of the 
result.  Something like...

MyService.myOperation.lastResult.myOperationResult.people.person.firstname

but I couldn't get that to work either.

[flexcoders] Re: Custom containers in Flex 2

2006-08-23 Thread thunderstumpgesatwork

The documentation has most of this covered... See this topic on
creating Advanced Visual components, and all the sub-topics. Read
several times. Example is in there too.
http://livedocs.macromedia.com/flex/2/docs/1721.html

This page specifically has an example on overriding the layout
mechanism of the VBox container:
http://livedocs.macromedia.com/flex/2/docs/1737.html

Here's a thread in flex-coders discussing the "correct" way to
dynamically add child components to a custom container:
http://groups.yahoo.com/group/flexcoders/message/47695

That should be enough to get you going (if you read, try, re-read, etc...)

good luck!
Thunder

[flexcoders] edit Date within DataGrid

2006-08-23 Thread ldyhwke24

I have a question in regards to editing a date in a DataGrid.

I have this code:








Where the labelFunction calls a function to edit and format a date 
(dd-mmm-), which works fine - but then I'd like to edit the date 
using the DateField. I know that it needs to be a date, but how does 
one do this? Do I need to create a custom itemrenderer to do this? 
When I use the DateField, the format of the date is funky and it 
doesn't show the correct date - unless I pick a new date.

thanks!

Rich,

 

The app takes memory up 7MB then drops
back to 5Mb on a GC run. There is no way to force the GC to run.

 

Can you also send me your browser, os,
player version. Also are you on a dual-core machine?

I have an

dataproviders are constantly updated which redraws the view. All look
fine visually, however the flash player continues to use more and more
memory.

I created a demo version of this at
http://www.everythingflex.com/flex2/MemoryTest/

I have buttons which up the amount of repeater items and then lower
them and also attemp to delete the arraycollection, delete the
dataprovider, etc but the memory never is recaptured.

The source is also provided.

Does anyone know how to get the garbage collection to run when the
repeaters content changes??

RE: [Junk E-Mail - LOW] [flexcoders] Re: Choice of backend systems - which provides













Dave,

 

That is not true.

 

Swaping RemoteObject and WebService is not as easy as you
make it out to be. Web Services typing errors are highly dependent on the
server side implementation. Your team knows how to configure the server side
with WebServices but most developers cannot do this.

 

With RemoteObject you get strong typing seamlessly in AMF3.

 

The move from WebServices to RemoteObjects is much easier
than the inverse.

 

But then again you all are pros at Web Services. J

One quite important thing to keep in mind is that in
many cases (say
Java) the exact same servant class can be used for either RemoteObject
or WebService, which means the server-side processing actually is
basically identical. It also means that switching from RemoteObject
to a web service is almost as simple as copying the classes from one
directory to another.

[Junk E-Mail - LOW] [flexcoders] Re: Choice of backend systems - which provides

Basically every webcontainer these days supports GZIP compression.  We
use Tomcat in many circumstances which is hyper configurable.  We can
actually tell it to only compress the SOAP traffic and to do so when
it exceeds N bytes etc.  So in effect we turn SOAP into a compressed
binary format. That makes that differential much less relevant.

[flexcoders] Benoit Hediard: iTunes MP3 in flash player issue

2006-08-23 Thread Amir

Hi 

This email is for Benoit Hediard: 

You submitted an issue saying that an MP3 that has ID encoded with 
iTunes doesn't play in flash player. 


I tried reproducing with itunes 6.0.5.20 , but it played just fine.
 

We also knew about an iTunes bug where the ID3 is encoded 
incorrectly, however my understanding was that the bug was fixed, 
which is the reason I couldn't repro with 6.0.5.20. So I closed out 
the issue when you first submitted it in the beta phase. 


Recently, you submitted this issue again, saying that you repro'ed 
with 6.0.5.20. I have not been able to repro. 


Can you please provide me the .mp3 file that you can't run in flash 
player 9? 


You ddin't leave your e-mail address, so this is why I'm sending out 
a blanket one to flexcoders yahoo group. 


Thanks,

I'm sure someone already pointed this out, but network latency is also 
afactor. AMF is a compressed format, so it can load faster and in that
