Maybe you should post some code then, because I think the error is coming from

 Probably whoever designed the date class wanted to represent a date

I finally decided to use two date properties on my value objects: One
date property holds the date as Unix timestamp, the other one holds
the date as a Flex Date() object. When the date is retrieved from
MySQL it is retrieved as a Unix timestamp (UNIX_TIMESTAMP()). 

For example, in Flex/Cairngorm my UserVO has these date properties:

public class UserVO implements ValueObject 
{
   public var activeStartDate : Date;
   public var activeStartDateUnix : Number;
   public var activeEndDate : Date;
   public var activeEndDateUnix : Number;
}

Whenever I need a date property as Flex Date() object, I do
conversions like these:

model.selectedUser.activeStartDate = new
Date(model.selectedUser.activeStartDateUnix*1000);

model.selectedUser.activeEndDate = new 
Date(model.selectedUser.activeEndDateUnix*1000);

I'd be happy if anyone could come up with a better solution.

[flexcoders] Re: Help with adding datagrid to non-visible Sprite

2006-08-23 Thread wayneposner

i've tried setting the height/width on the datagrid, the sprite the 
datagrid is being added to and the class level sprite, but nothing 
seems to work.  When I check the properties in the debugger the 
values for height/width are 0 regardless of what I tried to set them 
to.


var pdg:PrintDataGrid=new PrintDataGrid();
var s:Sprite=new Sprite();
pdg.explicitHeight=600;
pdg.explicitWidth=600;
pdg.setActualSize(600,600);
pdg.width=600;
pdg.height=600;
s.addChild(pdg);
s.height=600;
s.width=600;

My class executing this code extends Sprite so I've simply added 
this.width=600;
this.height=600;

to the constructor of my class.  Still no luck.  What am I doing 
wrong???

Thanks!

 There is an issue with printing non-visible content - one work

 add your datagrid and set it's data, then use callLater to fire

[flexcoders] validating editable columns in the datagrid

2006-08-23 Thread bharg.flex

Hi,
I have a datagrid, which has some 2 columns editable.
In order to validate those two columns, I am using the cellrenderer 
property of the grid. The validators are working fine, but my problem 
is,if I enter a wrong data in the editable field, I get the red 
boundary of the validator giving appropriate message, but still I can 
save that data to the database.
Generally we use IsStructureValid to do the checking before saving, 
but in this case, how do I achieve the same?

Thanks in advance :-)

Re: Choice of backend systems - which provides


I simply have to disagree here. We can demonstrate several inproduction 
applications which we have developed using SOAP XMLWebServices and they 
perform like a champ. One of them was the runnerup for last years MAX award. 
The majority of the applications wedevelop use this architecture and to date 
not a single time has aclient nor a user complained about the performance of 
runtime dataservices based on SOAP.There are a few false rumors that 
continue to creep up in the Flexcommunity about the performance issues 
around SOAP.There are benchmarks which show that AMF can be drastically 
fasterthan a SOAP call for the same data. Sometimes even 100% faster. 
Yupthat's true there are. But you have to peel away the layers of 
theonion to see the reality. Statistics can be misleading. Forinstance, 
if AMF is 300 milliseconds and SOAP is 600 milliseconds the100% difference 
isnt even relative. How many people do you know whocan even see 1/3 of a 
seconds difference? In the end raw marshallingisnt the issue, it is the user 
and their experience. Flex2 madeDRASTIC improvements it the performance of 
XML parsing and in our ownbenchmarks the delta between the two services 
choices is often as lowas 10%.Of a much greater impact that the 
marshalling time is the UI"shredding" and binding of the data. Most badly 
performing RIA'ssuffer from data being returned from the back-end in a 
format thatholds no fidelity with the RIA. This requires the RIA to tear 
apartthe returned structural data and place it into its own structures 
andobjects and bind those to UI controls. Developing your userexperience 
in a front-to-back approach which assures great fidelitybetween the data 
formats of the tiers can account for an order ofmagnitude performance 
increase. That is the kind of performanceincrease users will actually 
experience. There are many other very smart things you can do like 
extendingexisting controls to do streaming rendering of data to provide 
theperception of speed, server side paging, caching, etc. In the end 
perception is reality. All that matters from the UIperspective is the 
experience that the user has. Worring about 300milliseconds is like trying 
to debate the number of angels that coulddance on the end of a pin. If the 
user can't see them, it doesn'tmatter how many there are.The running 
rumor that you simply cannot develop first class RIAs inFlex using a SOAP

 Hi guys,
 
 I just wanted to let you know we released WebORB for Ruby on Rails
 today. The product is free and open-source (GPL license) and makes is
 super simple to integrate Flex and/or Flash Remoting applications with
 Rails. We implemented both AMF0 and AMF3 protocols as well as added
 support for service deployment via standard Flex configuration file
 (remoting-config.xml).
 
 From a Flex developer's perspective, WebORB for Rails looks like an
 FDS server - you create a Flex project, point it to an installation of
 WebORB and all registered Ruby destinations can be invoked from Flex.
 Flash Remoting apps will see WebORB for Rails as remoting gateway.
 
 Ruby developers will enjoy the same ease-of-use and convenience they
 are already accustomed to with Rails. You do not need to do anything
 special with your classes to expose them to Flex and Flash - WebORB
 automatically locates classes and adapts client side types to their
 Ruby counterparts.

RE: [flexcoders] Re: FDS Data Management quesion

2006-08-23 Thread Jeff Vroom













Yes, using a separate destination and DataService
instance for each object would give you individual control over objects managed
by those destinations. Because of how we implemented the client
side library, if you create more than one DataService for the same destination
in the same client they actually all end up mapping to the same collection of
objects.



There is one additional caveat which is
that the commit queue and merge queue are really
managed by a lower level object called the DataStore which is accessed via a
property in the DataService. By default each DataService has its own
DataStore so you should be fine but if you use managed associations (i.e. your
destination has a one-to-one, one-to-many, etc. tag defining a relationship
between two objects), they will share the same DataStore by default. This
is so that we can keep changes in order when there are dependencies between the
changes. For example if you create a new item, then change a property of
another item to refer to that newly created item, the server side really wants
to process that create first before it processes the update to refer to the
created item so we need one queue which stores both changes when you have
relationships. 



Yes, you can revert the changes for items
independently. Just call dataService.revertChanges(item).
We find all messages that affect that item and undo those changes and then
remove those messages from the queue.

Thanks for the explanation, I think I have a better

So, I think what I got from that is that if I want to have control
over each object that I commit, I have to use a separate DataService
for each one?

Thanks for logging the enhancement request, as selecting which managed
object to commit would be the ideal way to handle this. 

You mentioned that I cannot release a single item from a managed
collection, but is it possible to revert a single item in a managed
collection?

 First off, a bit about how FDMS works behind the scenes. As you change
 a property of an object, a PropertyChangedEvent is fired which tells
 FDMS of the change. A message is logged for the item indicating that
 the property is changed. If you change a second property on the object,
 we merge that property change event into to the first message. If
 autoCommit is false, when you call commit, all pending changes
are
 sent. So if you are not changing an item, nothing is sent but if you
 have changed items A and B and the changes were logged for these items,
 there is no way to just commit the changes for item B. You can
 individually revert changes made to items however but that will roll the
 state of the item back to its state before the change. 
 
 
 
 Now it is possible to release an item so that FDMS is no longer managing
 its state. At this point, FDMS will not be tracking changes to that
 item so you could call getItem on A and getItem on B, then releaseItem
 on A. Now only changes to B will be tracked. If you call fill and get
 a collection of objects, there is no way to release just a single item
 in the collection however.
 
 
 
 Your use case is an interesting one and it would not be hard for us to
 add a method which just commits the changes to a specify item so I'll
 add an enhancement for that.
 
 
 
 As for your final question, merge is used when you have set
 autoMerge=false and it will merge changes received by the server into
 the current managed set of items. As changes are received by a client
 for some set of managed items, by default they are automatically
 merged into the current versions of the items, but when you
turn
 autoMerge=false, they are queued up instead (the mergeRequired property
 is set in this case). At that point, you call merge to apply
those
 changes.

I think one thing not given enough consideration in this discussion is 
cost.  We've been developing an enterprise-type application in Flex 2 
and initially chose to use AMF Remoting.  At the time, the licensing 
costs were not available.  However, now that we know it will cost us 
$20K per CPU for unlimited connections we're reconsidering.  
Webservices provide a nice alternative, but the marshalling/compression 
done by the AMF engine between AS and Java is very powerful.  We've yet 
to start evaluating the third party products, so I can't speak to them 
yet.

[flexcoders] Collection View changes order on update

2006-08-23 Thread ssundke

Hi, 
I have bound a Collectionlist of a datagrid which renders the item 
as a checkbox. Im using the default bindling of the datagrid (for 
select and update) to update the selected value back to the 
Collection. This all works fine, and the checked value is reflected 
back into the collection and the source behind the collection. But I 
notice that when the value is set the collection randomly changes 
order hence from the UI the display checkbox keep moving up and down 
(though the selecton value is still correct on each item). Is there 
any reason why this is happening and anyway to prevent it? I just 
want my collection to retain the ordering of the source hence I also 
have not defined any ordering/sorting on my view.

Please suggest a solution.
My only datagrid column looks something like

mx:DataGridColumn dataField=totalOn editorDataField=selected 
rendererIsEditor=true headerText=At the change in column(s):
mx:itemRenderer
  mx:Component
mx:CheckBox label={data.displayName}

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

2006-08-23 Thread Tom Lee

In my world, 300 milliseconds does matter.  10 sequential calls and you have
3 seconds of latency, which is definitely in the realm of something the end
user would notice.

Sometimes the end user is a key decision maker comparing two apps
side-by-side and making a judgment call as to which one will be further
developed.  Sometimes the one that feels snappier wins.

Do I think I should have to be making 10 sequential web service calls? No.
But then again, I don't develop web services.

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

I simply have to disagree here.  We can demonstrate several in
production applications which we have developed using SOAP XML
WebServices and they perform like a champ.  One of them was the runner
up for last years MAX award.  The majority of the applications we
develop use this architecture and to date not a single time has a
client nor a user complained about the performance of runtime data
services based on SOAP.

There are a few false rumors that continue to creep up in the Flex
community about the performance issues around SOAP.

There are benchmarks which show that AMF can be drastically faster
than a SOAP call for the same data.  Sometimes even 100% faster.  Yup
that's true there are.  But you have to peel away the layers of the
onion to see the reality.  Statistics can be misleading.  For
instance, if AMF is 300 milliseconds and SOAP is 600 milliseconds the
100% difference isnt even relative.  How many people do you know who
can even see 1/3 of a seconds difference?  In the end raw marshalling
isnt the issue, it is the user and their experience.  Flex2 made
DRASTIC improvements it the performance of XML parsing and in our own
benchmarks the delta between the two services choices is often as low
as 10%.

Of a much greater impact that the marshalling time is the UI
shredding and binding of the data.  Most badly performing RIA's
suffer from data being returned from the back-end in a format that
holds no fidelity with the RIA.  This requires the RIA to tear apart
the returned structural data and place it into its own structures and
objects and bind those to UI controls.  Developing your user
experience in a front-to-back approach which assures great fidelity
between the data formats of the tiers can account for an order of
magnitude performance increase.  That is the kind of performance
increase users will actually experience.  

There are many other very smart things you can do like extending
existing controls to do streaming rendering of data to provide the
perception of speed, server side paging, caching, etc.  

In the end perception is reality.  All that matters from the UI
perspective is the experience that the user has.  Worring about 300
milliseconds is like trying to debate the number of angels that could
dance on the end of a pin.  If the user can't see them, it doesn't
matter how many there are.

The running rumor that you simply cannot develop first class RIAs in
Flex using a SOAP web services back-end is simply not accurate, and we
have the apps in production with our clients to prove it.

[flexcoders] Adobe, Help 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??

[flexcoders] Re: Cairngorm eLearning Course and Quiz - who's in?

2006-08-23 Thread quinnwong74

Hi guys,

I'm on the Breeze Training team and I'm currently learning Flex2 and
Cairngorm to potentially use in a future version of Breeze.  I would
love to help out with this effort.  

I'm not sure if people are familiar with Breeze Presenter or
Captivate, but we could potentially use this as a solution for
generating the quizzes.  Breeze Presenter is great for quickly putting
together training material.  All you need is PowerPoint and the Breeze
plugin.  There is a Quizzing wizard which allows you to easily create
true/false, multiple-choice and multiple answer questions.  We could
then host the content on the Breeze service and people could view the
courses there.  Breeze also has tracking features so we could report
on how learners answered different questions and so forth.  

I can help set up the account for free of charge, which is an added
plus :)  

Here's a link to Breeze Training if you guys are interested:

http://www.adobe.com/products/breeze/productinfo/features/training/ 

Please let me know if you're interested in this as a potential
solution.  I would definitely be happy to help out with this effort.

Thanks,

Quinn

[flexcoders] Bug in Using the XMLListCollection class Example and the Fix

2006-08-23 Thread Arul






Any one tried this example?

Flex 2 Developer's 
Guide  Building User Interfaces forFlex Applications  Using Data 
Providers and Collections  Using hierarchical data providers  Using an 
XML data provider 

http://livedocs.macromedia.com/flex/2/docs/wwhelp/wwhimpl/common/html/wwhelp.htm?context=LiveDocs_Partsfile=0513.html


"Using the XMLListCollection class" example has a 
serious problem, when you delete an item in the List, if it is a leaf node in 
the Tree it gets deleted too

This is happening because of cross references 
that exist (we are directly adding the node toListwhich still 
has references to myData, the tree dataProvider)

Solution to this problem is simple, we need to 
make a copy to add to the list, then everything will be all right

we just need to change the doTreeSelect function 
as follows

  // Add the item selected in 
the Tree to the List XMLList data provider. private function 
doTreeSelect():void 
{ if 
(prodTree.selectedItem) 
listDP.addItem(prodTree.selectedItem.copy()); 
} 
I've attached thebug fixedMXML as 
well

[flexcoders] Extending the List Component: Sticky Selection

2006-08-23 Thread lostinrecursion

Ok,

I have a client of mine who is stuck (no pun intended) on the idea of
having a List component to which he does not have to hold CTRL down to
do multiple selections.

Essentially, he wants to be able to click on items and have them be
selected and if they have already been selected, then deselect them.

As if he was holding the CTRL key down the entire time.

Could anyone help me with at least a starting point? I am totally
freaked out about this for some reason. LOL

[flexcoders] Re: Resizable, Collapsible, Draggable Panel??

2006-08-23 Thread Megan

Thank you for your help, I'm making progress!! I got
SizeableTitleWindow to work! Yay! It starts off really tiny, is there
a way to make the initial size a bit bigger? I'll look through the
code and see if I can tell what I need to change.

Also, is there some way I could get the two graphics you refer to
(upArrow.gif and downArrow.gif)?

I'm still getting errors on MaxRestorePanel once I fixed those things
I mentioned earlier.

The code below has the error 1059: Property is read-only.

public function MaxRestorePanel(){
  this.className = MaxRestorePanel; 
}

The code below has this error on both lines - 1067: Implicit coercion
of a value of type flash.display:DisplayObject to an unrelated type
mx.core:IFlexDisplayObject

var upAsset:IFlexDisplayObject = btStateUp.getChildByName(upIcon);
var downAsset:IFlexDisplayObject =  btStateDown.getChildByName(upIcon);

And these lines have 1120 - Access of undefined property allChildrenList

allChildrenList.addChild(btStateUp);
allChildrenList.addChild(btStateDown);


Thanks so much. :)

[flexcoders] Re: Extending the List Component: Sticky Selection

2006-08-23 Thread jgraham_us

Sound to me like you will need to handle the mouse click events on 
the List and manage the selection yourself.  Not positive though 
there might be an easier way to get around this, I haven't actually 
looked at the List source to tell.

It doesn't make any difference as the timings are on the client side, not the

There will be some difference in time required to handle requests on the server

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

2006-08-23 Thread Peter Watson













Darren,





If your XML nodes have attributes (ie.
node label=foo/node)  you can use the
labelField attribute to control the labels.



 mx:Tree
id=myTree labelField=@label/





If they dont (ie.
foobar/foo)  or if you want to do any sort of custom
label logic, you need to use the labelFunction attribute to set
the values appropriately.



mx:Tree
id=myTree2 labelFunction=myLabelFunc/



 public
function myLabelFunc (item:XML):String{

 

 //if
node has children

 if(item.children().toString()
!= ''){

 return
item.name();

 }

 //no
children, its a leaf so get the value

 else{

 return
item.toXMLString();

 }

 }

peter

Subject: [flexcoders] How to cast a WebService lastResult when CFC 
returnType=xml
Date: Fri, 18 Aug 2006 23:08:44 -0400

I have a ColdFusion Component (web service) that looks like...

cffunction name=getEmployees access=remote
output=false
returntype=xml
 cfxml variable=myxml
 people
 person
 firstnameJohn/firstname
 lastnameSmith/lastname
 job
 titleDoctor/title
 descriptionblah blah blah/description
 /job
 /person
 person
 firstnameJane/firstname
 lastnameDoe/lastname
 job
 titleLawyer/title
 descriptionblah blah blah/description
 /job
 /person
 /people
 /cfxml
 cfreturn myxml
/cffunction

and some Flex code that looks like...

?xml version=1.0 encoding=utf-8?
mx:Application
 xmlns:mx=http://www.adobe.com/2006/mxml
 creationComplete=TestService.getEmployees.send();
 mx:WebService id=TestService wsdl=http://localhost/hr.cfc?wsdl
 mx:operation name=getEmployees /
 /mx:WebService
 mx:Tree
 id=myTree
 width=50%
 height=50%
 showRoot=false
 dataProvider={TestService.getEmployees.lastResult}/
/mx:Application

But what I get is a Tree that looks like:

Flex doesn't seem to be able to extract the XML from the SOAP message, 
which
is just SOAP XML wrapping my XML data.

Changing the Operation's resultFormat from e4x to
xml to object
changes the amount of junk in the Tree, but doesn't fix the problem. As a
matter of fact, it works best when I leave off this attribute and let the
Operation decide what resultFormat to use.

Casting lastResult as XML or XMLList doesn't seem to help either, and
neither does
ArrayUtil.toArray(TestService.getEmployee.lastResult)

Is there something I need to do to the lastResult to get it to work in
Trees, DataGrids, etc? Like cast it as some other data type? Why doesn't
e4x parse the SOAP message properly and extract my XML?

Just about every example I can find out there shows people using 
HTTPService
to pull back just the XML data without the SOAP webservice stuff, or else
shows how to create XML inside the mxml code itself using mx:XML
but I 
can
find nothing that shows how to return XML from a CFC web service and
use/parse it in Flex properly (as easy as, say, a CFC that returns a Query
object.)

[flexcoders] CairngormEvent Antipattern

2006-08-23 Thread e_baggg

Hello group-
  I hadn't seen a previous post regarding this explicity so I wrote a
small blog about it. It helps reduce the #of classes that get created
when using Cairngorm (a big issue with me since the client is VERY
picky with their swf file sizes). This blog shows the code for usuing
a reusable CairngormEvent versus creating separate classes for each
dispatchable event.

http://ebaggg.blogspot.com/2006/08/cairngormevent-anti-pattern-we-all.html

Thoughts?

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

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.

[flexcoders] Re: Webservice Destination with Basic Authentication

2006-08-23 Thread someguy7_7

I cannot see the authorization header anywhere in the http dump. Here
is some more information on how I am testing. I deployed the fds
samples.war and placed my test mxml in the samples application. I
added the following definition to samples/WEB-INF/flex/proxy-config.xml.
destination id=mytest
adapter ref=soap-proxy /
properties
wsdlhttp://machine/app/webservice/wsdl/wsdl
soaphttp://machine/app/services/myService/soap
/properties
/destination

Do I need to add some security constraints to the destination definition?

See the issue you have isnt with the choice of marshalling prototcol.
 The issue is with an API that holds no fidelity with the user

multiple sequential calls.  In other cases it can be much worse where

 Subject: [Junk E-Mail - LOW] [flexcoders] Re: Choice of backend

 I simply have to disagree here.  We can demonstrate several in
 production applications which we have developed using SOAP XML
 WebServices and they perform like a champ.  One of them was the runner
 up for last years MAX award.  The majority of the applications we
 develop use this architecture and to date not a single time has a
 client nor a user complained about the performance of runtime data
 services based on SOAP.
 
 There are a few false rumors that continue to creep up in the Flex
 community about the performance issues around SOAP.
 
 There are benchmarks which show that AMF can be drastically faster
 than a SOAP call for the same data.  Sometimes even 100% faster.  Yup
 that's true there are.  But you have to peel away the layers of the
 onion to see the reality.  Statistics can be misleading.  For
 instance, if AMF is 300 milliseconds and SOAP is 600 milliseconds the
 100% difference isnt even relative.  How many people do you know who
 can even see 1/3 of a seconds difference?  In the end raw marshalling
 isnt the issue, it is the user and their experience.  Flex2 made
 DRASTIC improvements it the performance of XML parsing and in our own
 benchmarks the delta between the two services choices is often as low
 as 10%.
 
 Of a much greater impact that the marshalling time is the UI
 shredding and binding of the data.  Most badly performing RIA's
 suffer from data being returned from the back-end in a format that
 holds no fidelity with the RIA.  This requires the RIA to tear apart
 the returned structural data and place it into its own structures and
 objects and bind those to UI controls.  Developing your user
 experience in a front-to-back approach which assures great fidelity
 between the data formats of the tiers can account for an order of
 magnitude performance increase.  That is the kind of performance
 increase users will actually experience.  
 
 There are many other very smart things you can do like extending
 existing controls to do streaming rendering of data to provide the
 perception of speed, server side paging, caching, etc.  
 
 In the end perception is reality.  All that matters from the UI
 perspective is the experience that the user has.  Worring about 300
 milliseconds is like trying to debate the number of angels that could
 dance on the end of a pin.  If the user can't see them, it doesn't
 matter how many there are.
 
 The running rumor that you simply cannot develop first class RIAs in
 Flex using a SOAP web services back-end is simply not accurate, and we
 have the apps in production with our clients to prove it.

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

2006-08-23 Thread Andrew Trice













OK, so Ive watching this thread
going back and forth over and over Now its time for my two cents.
It looks like this thread began by someone saying that you cannot use web
services in a real world flex application. Ive got to agree with
Dave on this. You definitely can, and we have done it numerous times here
at Cynergy. 



Are there tradeoffs? Yes. As
others have said already in the post: The decision on what mechanism to
use should be dealt with on a case by case basis. Lets
consider a few things:




 Do
 the web services already exist and can they handle the current load? If
 they do, use them. Why reinvent the wheel? 
 Yes,
 there is a performance advantage to using AMF, but most users will not
 notice the difference in transport speed it is fractions of a
 second. If your application is properly architected and your backend
 is optimized, the end user will never know the difference.






I personally like using remote objects,
but not every solution allows for this. In the cases where you cannot use
remote objects, web services still work great. SOAP is a very verbose
protocol, but by no means is it unusable. If that were the case, why
would web services be so prevalent? Why would there be all the buzz about
service oriented architectures? 



If you feel that a web service is too
verbose or too slow, and you cant use remote objects, then use a
HTTPService to return XML. There are many solutions. It really all
boils down to how you use and retrieve your data and depends on your requirements
and application architecture. If the processing time on the server
is too much for your application to handle, then chances are there is a problem
with your applications back end, not the webservice/serialization layer.




To generalize and say that you should
never use a web service is a very big mistake.

 Martin:
  
 OK . . . . so the lag time is when the data gets back to the end-user?

exactly, its the time it takes for the flash player or actionscript code to 
convert the incoming data into a format usable by the application.

Before in the flash world that was a big deal as XML processing was expensive 
and often tedious to code whilst remoting was natively implemented and provided 
you with typed business objects as a result of the call.

With Flex 2 the differences are not so important as the features like data 
binding and e4x pretty much level the playing field for the data formats.


 Bottom line . . . . with all things being equal . . . .

 If the answer is . . . . it depends on the data being requested and/or the
 data format then that seems to suggest that everyone must run tests to 
 compare results and then test again based on scaling up.

I suppose one of the main factors would be the server code that handles the 
incoming request and then transforms the business data into the required format 
to send back to the client.

That could be anything from some hand written php code to a commercial remoting 
gateway.

Its so context dependent that its impossible to make a general statement of the
type 'Remoting performs better than Web Services'

It would be interesting to see a comparison of the throughput you could expect 
when comparing different solutions on the same server hardware, e.g. PHP 
Nu-Soap against AMFPHP.. Jrun's remoting vs. OpenAMF vs JAX-WS etc..

and where they each perform the same business operation and return the same 
data..

but then there are other concerns such as memory usage and what else the server 
is used for and how it performs for those use cases.

thats what i mean by you have to take it on a case by case basis.

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

2006-08-23 Thread Tom Lee

I'm sure someone already pointed this out, but network latency is also a
factor.  AMF is a compressed format, so it can load faster and in that sense
make your app more responsive.  With XML web services, the tags themselves
add a degree of overhead.  There are schemes for compressing web services
which can help.

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

2006-08-23 Thread Mark Piller

 In the cases where you cannot use remote objects, web services still
work great

Andrew, do you have any examples when one would not be able to use
remote objects? I am interested to know if you have any technical
reasons, rather than just economical.

Cheers,
Mark

 OK, so I've watching this thread going back and forth over and over...
 Now it's time for my two cents.  It looks like this thread began by
 someone saying that you cannot use web services in a real world flex
 application.  I've got to agree with Dave on this.  You definitely can,
 and we have done it numerous times here at Cynergy.  
 
  
 
 Are there tradeoffs?  Yes.  As others have said already in the post:
 The decision on what mechanism to use should be dealt with on a case by
 case basis.  Let's consider a few things:
 
  
 
 1.Do the web services already exist and can they handle the
 current load?  If they do, use them.  Why reinvent the wheel?  
 2.Yes, there is a performance advantage to using AMF, but most
 users will not notice the difference in transport speed... it is
 fractions of a second.  If your application is properly architected and
 your backend is optimized, the end user will never know the difference.
 
  
 
 I personally like using remote objects, but not every solution allows
 for this.  In the cases where you cannot use remote objects, web
 services still work great.  SOAP is a very verbose protocol, but by no
 means is it unusable.  If that were the case, why would web services be
 so prevalent?  Why would there be all the buzz about service oriented
 architectures?  
 
  
 
 If you feel that a web service is too verbose or too slow, and you can't
 use remote objects, then use a HTTPService to return XML.  There are
 many solutions.  It really all boils down to how you use and retrieve
 your data and depends on your requirements and application architecture.
 If the processing time on the server is too much for your application to
 handle, then chances are there is a problem with your application's back
 end, not the webservice/serialization layer.  
 
  
 
 To generalize and say that you should never use a web service is a very
 big mistake.

2006-08-23 Thread Tom Lee

Exactly so.  My experience has been that some folks expect the Flash
platform to be a means of improving the user experience for legacy systems.
The data services themselves can't change: they're in use already by
partners, or by other front ends.  So, you end up going through a lot of
client-side gyrations to give the illusion of better performance.  Using AMF
to squeeze every last bit of performance out of the data transfer can be an
option, because you can implement as middleware.

It looks like the original message was dealing with starting from scratch
though... So I won't hijack the thread any further. ;)

See the issue you have isnt with the choice of marshalling prototcol.
 The issue is with an API that holds no fidelity with the user
experience you are trying to present.  In your case having to make
multiple sequential calls.  In other cases it can be much worse where
the RIA has to shread and re-combine data feeds to match the experience.  

This is exactly what I pointed out as being one of the largest
contributors to a poorly peforming RIA.  It is the elephant in the room.

 Subject: [Junk E-Mail - LOW] [flexcoders] Re: Choice of backend

 I simply have to disagree here.  We can demonstrate several in
 production applications which we have developed using SOAP XML
 WebServices and they perform like a champ.  One of them was the runner
 up for last years MAX award.  The majority of the applications we
 develop use this architecture and to date not a single time has a
 client nor a user complained about the performance of runtime data
 services based on SOAP.
 
 There are a few false rumors that continue to creep up in the Flex
 community about the performance issues around SOAP.
 
 There are benchmarks which show that AMF can be drastically faster
 than a SOAP call for the same data.  Sometimes even 100% faster.  Yup
 that's true there are.  But you have to peel away the layers of the
 onion to see the reality.  Statistics can be misleading.  For
 instance, if AMF is 300 milliseconds and SOAP is 600 milliseconds the
 100% difference isnt even relative.  How many people do you know who
 can even see 1/3 of a seconds difference?  In the end raw marshalling
 isnt the issue, it is the user and their experience.  Flex2 made
 DRASTIC improvements it the performance of XML parsing and in our own
 benchmarks the delta between the two services choices is often as low
 as 10%.
 
 Of a much greater impact that the marshalling time is the UI
 shredding and binding of the data.  Most badly performing RIA's
 suffer from data being returned from the back-end in a format that
 holds no fidelity with the RIA.  This requires the RIA to tear apart
 the returned structural data and place it into its own structures and
 objects and bind those to UI controls.  Developing your user
 experience in a front-to-back approach which assures great fidelity
 between the data formats of the tiers can account for an order of
 magnitude performance increase.  That is the kind of performance
 increase users will actually experience.  
 
 There are many other very smart things you can do like extending
 existing controls to do streaming rendering of data to provide the
 perception of speed, server side paging, caching, etc.  
 
 In the end perception is reality.  All that matters from the UI
 perspective is the experience that the user has.  Worring about 300
 milliseconds is like trying to debate the number of angels that could
 dance on the end of a pin.  If the user can't see them, it doesn't
 matter how many there are.
 
 The running rumor that you simply cannot develop first class RIAs in
 Flex using a SOAP web services back-end is simply not accurate, and we
 have the apps in production with our clients to prove it.

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

2006-08-23 Thread Ted Patrick













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 its 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 road and have learning all the tricks to making this stack work
very well for their clients. Looking back and knowing what I know now about Flex
Data Services much of this hard work could have been dramatically simplified
and automated (but then again Flex 2/FDS hadnt shipped yet). FDS makes
all this hard work evaporate and makes easy for anyone to exchange data like an
industry leading professional.



The really funny part is that we are only talking about
the RPC portions of Flex Data Services. Messaging and Data Management are
really valuable features to understand and explore. These two features are 70%
of the FDS product. We(Adobe) need to do a better job of making this value crystal
clear. 



Flex Data Services is the most productive and high
performance way to exchange data with the Flash Player. Period, Hands Down,
Next!



My 2 cents,

[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,

[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.

 Nu-Soap against AMFPHP.. Jrun's remoting vs. OpenAMF vs JAX-WS etc..
 
 and where they each perform the same business operation and return
the same
 data..
 
 but then there are other concerns such as memory usage and what else the
 server 
 is used for and how it performs for those use cases.
 
 thats what i mean by you have to take it on a case by case basis.

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

2006-08-23 Thread Ted Patrick













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

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











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.

I have buttons which up the amount of repeater items and then lower

[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:

mx:DataGrid id=memberGrid width=480 height=140 editable=true
mx:columns
mx:DataGridColumn textAlign=left dataField=fullName 
headerText=Name/
mx:DataGridColumn labelFunction=formatDate headerText=Start Date 
itemRenderer=mx.controls.DateField editorDataField=selectedDate/
/mx:columns
/mx:DataGrid

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!

  develop use this architecture and to date not a single time has a

  There are a few false rumors that continue to creep up in the Flex
  community about the performance issues around SOAP.
 
  There are benchmarks which show that AMF can be drastically faster
  than a SOAP call for the same data.  Sometimes even 100% faster.  Yup
  that's true there are.  But you have to peel away the layers of the
  onion to see the reality.  Statistics can be misleading.  For
  instance, if AMF is 300 milliseconds and SOAP is 600 milliseconds the
  100% difference isnt even relative.  How many people do you know who
  can even see 1/3 of a seconds difference?  In the end raw marshalling
  isnt the issue, it is the user and their experience.  Flex2 made
  DRASTIC improvements it the performance of XML parsing and in our own
  benchmarks the delta between the two services choices is often as low
  as 10%.
 
  Of a much greater impact that the marshalling time is the UI
  shredding and binding of the data.  Most badly performing RIA's
  suffer from data being returned from the back-end in a format that
  holds no fidelity with the RIA.  This requires the RIA to tear apart
  the returned structural data and place it into its own structures and
  objects and bind those to UI controls.  Developing your user
  experience in a front-to-back approach which assures great fidelity
  between the data formats of the tiers can account for an order of
  magnitude performance increase.  That is the kind of performance
  increase users will actually experience.
 
  There are many other very smart things you can do like extending
  existing controls to do streaming rendering of data to provide the
  perception of speed, server side paging, caching, etc.
 
  In the end perception is reality.  All that matters from the UI
  perspective is the experience that the user has.  Worring about 300
  milliseconds is like trying to debate the number of angels that could
  dance on the end of a pin.  If the user can't see them, it doesn't
  matter how many there are.
 
  The running rumor that you simply cannot develop first class RIAs in
  Flex using a SOAP web services back-end is simply not accurate, and we
  have the apps in production with our clients to prove it.

[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!

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

2006-08-23 Thread Darren Houle

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...

mx:TextArea 
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.

Darren,

If your XML nodes have attributes (ie. node label=foo/node) - you
can use the 'labelField' attribute to control the labels.

 mx:Tree id=myTree labelField=@label/

If they don't (ie. foobar/foo) - or if you want to do any sort of
custom label logic, you need to use the 'labelFunction' attribute to set
the values appropriately.

mx:Tree id=myTree2 labelFunction=myLabelFunc/

 public function myLabelFunc (item:XML):String{

 //if node has children

 if(item.children().toString() !=
''){

 return item.name();

 }

 //no children, it's a leaf so get
the value

 else{

 return
item.toXMLString();

 }

 }

 But what I get is a Tree that looks like:
 
 Flex doesn't seem to be able to extract the XML from the SOAP message,
 which
 is just SOAP XML wrapping my XML data.
 
 Changing the Operation's resultFormat from e4x to xml to object
 changes the amount of junk in the Tree, but doesn't fix the problem. As
a
 matter of fact, it works best when I leave off this attribute and let
the
 Operation decide what resultFormat to use.
 
 Casting lastResult as XML or XMLList doesn't seem to help either, and
 neither does
 ArrayUtil.toArray(TestService.getEmployee.lastResult)
 
 Is there something I need to do to the lastResult to get it to work in
 Trees, DataGrids, etc? Like cast it as some other data type? Why
doesn't
 e4x parse the SOAP message properly and extract my XML?
 
 Just about every example I can find out there shows people using
 HTTPService
 to pull back just the XML data without the SOAP webservice stuff, or
else
 shows how to create XML inside the mxml code itself using mx:XML but
I
 can
 find nothing that shows how to return XML from a CFC web service and
 use/parse it in Flex properly (as easy as, say, a CFC that returns a
Query
 object.)

[flexcoders] Similar Node Access Question

2006-08-23 Thread Darren Houle

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...

?xml version=1.0 encoding=utf-8?
mx:Application
xmlns:mx=http://www.adobe.com/2006/mxml;
creationComplete=IACleanService.authenticateUser.send()

mx:WebService id=IACleanService 
wsdl=http://localhost/ia_cleanup.cfc?wsdl;
mx:operation name=authenticateUser
mx:request xmlns=
usernamejsmith/username
passwordasdf1234/password
/mx:request
/mx:operation
/mx:WebService

mx:DataGrid height=400 width=400
dataProvider={IACleanService.authenticateUser.lastResult} /

mx:TextArea width=400 height=400
text={IACleanService.authenticateUser.lastResult.fullname} /

/mx:Application

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

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] 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?

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

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.

If you do [Bindable(event=unmanaged)]
it is your responsibility to dispatch the unmanaged event. If you just do

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] Functionality Between Components and the Main Application

2006-08-23 Thread Megan

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!

Your custom component should dispatch its events. The parent application
which should be listening for them. 

Something like this might work:

.MuteButton {
upSkin: Embed(source=/skin_assets/AudioOn.png);
downSkin: Embed(source=/skin_assets/AudioOff.png);
selectedUpSkin: Embed(source=/skin_assets/AudioOff.png);
selectedDownSkin: Embed(source=/skin_assets/AudioOn.png);

[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!

[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

[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;mx:HBox id=panelParent mouseOver=overMouse(event) mouseOut=outMouse(event) width=100% height=100%
 //This container will cause the parent to dispatch the mouseOut event because of the backgroundImage // remove the backgroundImage and it doesn't happen  mx:HBox id=flag_start_box height=100% width=50% backgroundImage={flag_start} / 
/mx:HBoxThanks in advance,Brendan

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

2006-08-23 Thread Darren Houle

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?

Hi Barry,



Im not sure if I can be of much help here. Im not into PHP, Im not into
FDS and remoting and the AMF protocol that is related to it. For me, but
that is totally a personal opinion, the only acceptable solution for
communication with a back-end is webservices, and nothing else. Briefly 
here
are my reasons:

*  The coolest thing about Flex is not the graphics ... but that you
can make your server stateless, meaning that you obtain 100% fail-over
characteristics including linear scalability. With FDS (or any other 
related
solution) you highly likely lose this feature and my guess is that
scalability will be tougher to achieve; for sure it is harder to guarantee
... with a stateless server solution you can. And we always want to grow
with our applications, dont we???
*  I like to keep my Flex layer totally independent of my back-end
layer. My back-end layer should not be aware by any means of the client
technology. With webservices you realize this. With FDS (or any other
related solution) you get a vendor lock-in, which I consider undesirable.
*  The trend in my business is that more and more you get projects only
for a front-end or back-end solution. In the past it occurred more that you
had to build them together, but that is changing. Its very acceptable to
request a back-end to expose its operations through webservices. Its not
very accetable to request them to expose it via FDS or something like that.



To be fair, there are some disadvantages using web services as well; among
others:

*  No automatic conversion of the web service results into your custom
action script classes. You have to make converters yourself to accomplish
this. With FDS/AMF I understand you can have this conversion automatically
done for you.
*  Performance. People tend to say that webservices are slow. Its true
that the serialization/deserialization of the XML (both on client and
server) side takes computing time. My experiences so far are that this 
extra
computing time is not causing any serious damage in the user experience.
*  Flex has some trouble communicating with DOC/Literal encoded
webservices. Especially in the .Net corner this is causing problems. But
that should be temporarily ... The adobe guys are working on it and
hopefully in a next release these issues will be fixed.



For me the advantages of webservices by far outweigh the disadvantages. So
if you ask me: use webservices! You keep your freedom ...



Cheers,

Franck

Franck and Doug: may I be so bold as to include here some information
I sent to our programming team for them to have some context?

I offer it here as a talking point only - and would invite any
comments or corrections to help me gain a better understanding myself
... this has just been gathered by my own ad-hoc investigations. the
context of the email was a report that Adobe were seriously targeting
PHP developers for Flex.


regarding Flash remoting: some background to put it into context:

there are three basic ways of getting communication happening between
a SWF (now-a-days built with Flex) and server-side code:

webservices
XML HTTP requests
Flash Remoting (using the Async Message Format - AMF)

PHPAMF (Flash remoting with PHP) is not a Macromedia/Adobe product. It
was reverse engineered by the PHP community to use Flash remoting.
It's been around for a few years (that I know of) and may be even more
popular than CF-AMF (don't know for sure)

here's the important bit:

PHPAMF, OpenAMF, the Adobe .NET/ Java remoting add-in and ColdFusion
6.1 remoting all use the AMF0 protocol. ColdFusion 7.02 and
FlexDataServices (Java) all use AMF3

What's the diff? 2 things:
Apart from some removal of dumb stuff-ups and a reduction of data
packet size (thanx to new encoding), AMF3 is very strongly typed which
allows a seamless (and easy) mapping/conversion between server side
objects (eg: Java value objects and ColdFusion's CFC's). This is why
FlexBuilder can have a simple wizard to take your CFC and create
Actionscript classes from it (and/or visa-versa). Before it was all
manual with a tonne of testing

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

2006-08-23 Thread Seth Hodgson

Hi Jim,

Try tagging the properties that you don't want managed in your [Managed] AS

logged/committed.

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.

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 if I'm doing

why won't the treeCalendar.selectedNode property accept this value?

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?

Ok got some information for you:



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

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

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.

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 cant 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 MenuBars
dataDescriptor to walk the MenuBars 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
MenuBars 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 MenuBars
dataDescriptor and find the node you want to disable and use
IMenuDataDescriptor.setEnabled() to disable that node.

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?

   Hi Jeff,
   
   You can handle this with binding. Something like this:
   
   menuItem label=File enabled={model.FileMenuEnabledFlags
(0)}
   menuItem label=New enabled={model.FileMenuEnabledFlags
  (1)}/
   menuItem label=Open 
enabled={model.FileMenuEnabledFlags
  (2)}/
   menuItem label=Save 
enabled={model.FileMenuEnabledFlags
  (3)}/
   /menuItem
   
   model.FileMenuEnabledFlags is an array of Boolean values.

Anyone have a clue how to disable a menu bar item, when it

Given a structure like this:
menuItem label=File
menuItem label=New /

menuItem label=Save /
/menuItem
   
I can easily get a handle on the root node
(File), by 
 accessing
myMenu.menuItems[0], however, i'm banging my head
against 
the 
  wall
trying to get a handle on Save as a MenuBarItem, as the
File 
 item
doesnt seem to have child items representing the others.
   
Can someone point me in the right direction here?
   
Thanks

[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!

Alert.show(cvcompanyValue.selectedItem.data);selectedItem 'holds' the complete object in the dataprovider that is selected. This is a really neat uber kewl treat, eh?Ironically a coworker asked me the same question minutes ago.
