I had the same problem, ordered FlexBuilder 3 Professional upgrade  
this morning, in the email confirmation entitled Your Serial Numbers  
it said Contact Customer Service under Adobe Flex Builder 3  
Professional (Mac/Win,English), and on my downloads page in my Adobe  
account it also said Contact Customer Service in place of a serial  
number.

So I contacted our local (UK) customer service, spoke to a nice lady  
who checked out my order and said she'd get back in contact when she  
got the serial number.

Although she was supposed to send it by email, she called and said  
that I should now have an email with the serial number. I didn't have  
it, but she said I should be able to see it in the downloads in my  
online account. I went online (keeping her on the phone until I could  
verify), and sure enough my serial number was there.

I have my serial number, after a little wait, hopefully the bug in  
serial number delivery has been fixed by now.

No question about it; having a degree will make you more hireable.

RE: [flexcoders] Re: AIR and LCDS, Channel.Connect.Failed error

2008-02-14 Thread Battershall, Jeff

Eduard,

I wouldn't depend on the compiler to determine your endpoints in an AIR
application. I'm doubting that approach will work. 

When I init my app, I create channelSets and add channels to them, and
each remote object's channelSet property are bound to one of these
channelSets. 

Bottom line is I'm defining my channels/channelsets programmatically and
setting the endpoints during this process.  It works just fine.

Jeff, thanks for your reply. 

Unfortunately setting the endpoint on the RemoteObject does not make 
any difference and generates the same error with the same faulty URL.

Seems like it is ignored completely. I tested by setting the wrong 
endpoint in my working Flex 3 application in order to check if the 
endpoint is indeed processed when a -service directive is given to 
the compiler. The answer is yes it does overrule the -service 
directive. So setting the endpoint does work in Flex 3 but not in 
AIR.

 Subject: [flexcoders] AIR and LCDS, Channel.Connect.Failed error
 
 
 The project I'm working on is using Flex 3 (latest beta) and LCDS
 2.5.1 running under Tomcat 6.x. The service consists of a Java 
class 
 and is correctly defined in the remoting-config.xml
 
 All things work as they should.
 
 Now I want to move the project to a AIR application. I know how to
 setup an AIR application and moving from a working Flex 3 
application 
 to an AIR application is no big deal.
 
 The project compiles without problems and the -services directive
 points to the services-config.xml, the same one from the working 
Flex 
 3 application. So one expect things to be alright but then things
 fall apart. As soon as the AIR application is launched and tries to 
 connect to the destination, the following error occurs.
 
 [FaultEvent fault=[RPC Fault faultString=Send failed
 faultCode=Client.Error.MessageSend 
 faultDetail=Channel.Connect.Failed error 
NetConnection.Call.Failed: 
 HTTP: Failed: url: 'http://oolWall_AIR.swf/coolwall/messagebroker/
 amf'] messageId=8E8E8B57-66F0-D797-2B5E-137734E88D9C
type=fault 
 bubbles=false cancelable=true eventPhase=2]
 
 It is immediately obvious that the url is not correct. The host
name 
 and port is missing and even the first letter C is missing from
  .swf
 file name. It should have read http://localhost:8080/coolwall/ 
 messagebroker/amf but apparently the AIR application is using the
  .swf
 file name minus the starting Capital character as the host name
 and port number. 
 
 I use a program called ServiceCapture to capture the network
chatter 
 and it confirmed me that the host name and port number is indeed
 wrong. I mean it could also be a faulty debug trace statement but 
 this proofs that the generated URL when using AIR and LCDS is 
wrong. 
 
 In the Adobe Flex Builder Jira bug tracking system there is an
issues 
 which has been closed a couple of month ago and dismisses it as an
 error of either LCDS or AIR. The workaround is handcoding the exact 
 URL in the remoting-config.xml file which is ofcourse not very 
 sensible. I cannot judge which product is the one to blame as I 
lack 
 the knowledge to do so.
 
 So does anyone (Adobe?) know which product (FB, AIR, LCDS?) is
faulty 
 and when it will be fixed. Thank you very much.

RE: [flexcoders] BlazeDS - Unknown destination error

2008-02-14 Thread Jeff Vroom

Make sure that either you are pointing your compiler at the
services-config.xml which defines those destinations or you need to
define a channel set on the client and set the channelSet property on
your service.  

 

You can see what destinations are getting compiled into your app via the
static variable:  flex.messaging.config.ServerConfig.xml.   That should
be a subset of the info from services-config.xml if you are compiling
stuff in.

Subject: [flexcoders] BlazeDS - Unknown destination error

 

I'm trying to get BlazeDS working with our existing Flex application.
When the application starts and tried to subscribe to a publisher, I
get the following error:

[MessagingError message='Unknown destination 'userTopic'.']
at mx.messaging.config::ServerConfig$/getChannelSet()
[C:\dev\enterprise_bali\frameworks\mx\messaging\config\ServerConfig.as:2
24]
...

I have the topic defined in my messaging-config.xml file like this:
destination id=userTopic/destination

Not really sure what the deal is. I've converted our app to use the
Flex 3 plugin for Eclipse, and that seems OK (not sure if I really
needed to do this). The only thing I see is that the properties of
the main flex project say Project is being compiled with Flex 3.0,
but server has Flex 2.0.1 in the Flex Compiler section. Ummm, say what?

Any help would be appreciated.

RE: [flexcoders] Re: BlazeDS - Unknown destination error

2008-02-14 Thread Jeff Vroom

Sorry for the terse description - it's been a little busy here!

 

For Point 1, the stuff you have there looks like the server itself is
starting up fine.   The issue is that when you compile your SWF, the
tool you use to compile your SWF also should refer to the
services-config.xml file.  If you are using flex builder, there is a
setting for that in your project properties.   If you are requesting the
MXML file directly from the browser (where the server compiles the mxml
file to produce the SWF), this is in your flex-config.xml file.  If you
are compiling using ant or the command line compiler there is a
-services option to the compiler.   

 

For Point 2, since you do not set the channelSet property on your
Consumer component, you need to follow the step in point 1.  There is
another option where the client downloads the configuration for your
destination from the server when it connects.  But for that to work, you
need to specify the URL to the server so it can connect in the first
place.  You do that with the channelSet property.  

 

For Point 3, you can see this by adding the MXML tag:

 

 mx:TraceTarget/

 

If you are using the debug player, you'll see some diagnostics in the
flashlog.txt file.  That gets buried in the user's home directory on
windows under application data/macromedia/flash player/logs.  Make sure
you have the debug player though since the release player doesn't output
trace information.  You can also get to this property directly in
actionscript with:

 

   import flex.messaging.config.ServerConfig;

 

 

   

 

   trace(ServerConfig.xml);

I hate to say it, but I don't know how to do any of that.

-- Point 1 --
[point] your compiler at the services-config.xml which defines those
destinations
Here are a couple lines of debug output from the console. I think I'm
pointing to the correct config files.
[Flex] [Configuration] BlazeDS - Community Edition: 3.0.0.353
[Flex] [Configuration] Endpoint my-streaming-amf created with
security: None
[Flex] [Startup.Destination] Destination with id 'userTopic' is

[Flex] [Startup.Service] Service with id 'message-service' is ready
(startup time: '0' ms)
[Flex] [Startup.MessageBroker] MessageBroker with id '__default__'
is ready (startup time: '407' ms)
So to me, that part of the configuration is correct.

-- Point 2 --
define a channel set on the client and set the channelSet property on
your service

This is my code in main.mxml to define my consumer:
mx:Consumer id=userConsumer destination=userTopic
message=onUsersFeed(event)/

And the corresponding code in AS to subscribe to the destination.
public function onCreationComplete():void
{ 
// Subscribe to destination
userConsumer.subscribe();
}

Am I doing something wrong here? I basically took this from one of
the BlazeDS samples.

-- Point 3 --
You can see what destinations are getting compiled into your app via

I don't know how to access this variable. Is this a Java variable?

RE: [flexcoders] Re: Flex Data Management and container's UserTransaction

2008-02-14 Thread Jeff Vroom

Answers inline:

Thanks Jeff. 
1. This is all happening in remote Service (I dont have access to
assembler's transaction there). Hence I am creating new
DataServiceTransaction. Does refresh and update happen on a different
thread? For assemblers, I use Hibernate Interceptor which works great.

When you call dst.commit() the entire refresh of the fills happens
inside of that call.   All pushed messages are also put into the client
queues synchronously as part of that call.   


2. singleSession = true binds a session to a threadLocal, so the same
session should be available to all as long as its happening on the
same thread



Interesting... so it seems like the problems you were seeing are still
not explained?


3. If we have one-many relation(parent child) in assembler, which
points to the same assembler. If a child changes outside of the scope
of the assembler, do we need to send refresh on the child only or
parent only or the recursively from top most parent to bottom most
child.



If the property values of the child items change, you only need to call
updateItem on the child destination.  If a child item is added or
removed from an association that happens on the parent destination.
When you use auto-sync, we keep track of the reference graph and so can
route the changes to the appropriate clients just knowing the leaf
change.  We walk back up the reference graph to find all clients that
are looking at that item.

 Hi Shailesh,
 
 
 
 I'm not sure what the problems are... It sounds like you are using the
 DataServiceTransaction.begin() and commit() methods yourself (the
other
 way this can be used is if you call the
 DataServiceTransaction.getCurrentDataServiceTransaction() call from
 inside of an assembler method such as createItem). When you call
 begin, if you specify useJTA=false I think that when you call
commit()
 on the data service transaction that those calls should go out no
matter
 what. By the time this calls is made though, we will assume that the
 changes you are telling us about have been applied to the data base
and
 either have already been committed. It could be that you are calling
 commit() just before the transaction has been committed? The part
 that could go wrong there is the refresh fill process. If you call
 createItem() and then commit(), the commit will go through each
 managed fill and potentially re-execute those queries to pick up the
 newly added item. If this fill call re-queries the database so it does
 not see the change applied, it would not refresh it properly.
 
 
 
 It might be that in one mode you are using the HibernateAssembler
picks
 up the same session and so sees those changes and in the other mode is
 picks up a different session? I'm not sure... if you still have
 questions and can generate a server debug log for the problematic case
 I'm happy to take a look.

 Turned out that Its not the transaction, its OpenSessionInViewFilter's

 So, in a nut shell, If you have,
 1. singleSession = true, DataServiceTransaction wouldnt send out the

RE: [flexcoders] AIR and LCDS, Channel.Connect.Failed error

2008-02-13 Thread Battershall, Jeff

AFAIK, an AIR application doesn't have a domain context the way a Flex
app would. 

You need to specify the endpoint for your channels in an AIR
application.

Subject: [flexcoders] AIR and LCDS, Channel.Connect.Failed error


The project I'm working on is using Flex 3 (latest beta) and LCDS 
2.5.1 running under Tomcat 6.x. The service consists of a Java class 
and is correctly defined in the remoting-config.xml

All things work as they should. 

Now I want to move the project to a AIR application. I know how to 
setup an AIR application and moving from a working Flex 3 application 
to an AIR application is no big deal. 

The project compiles without problems and the -services directive 
points to the services-config.xml, the same one from the working Flex 
3 application. So one expect things to be alright but then things 
fall apart. As soon as the AIR application is launched and tries to 
connect to the destination, the following error occurs.

[FaultEvent fault=[RPC Fault faultString=Send failed 
faultCode=Client.Error.MessageSend 
faultDetail=Channel.Connect.Failed error NetConnection.Call.Failed: 
HTTP: Failed: url: 'http://oolWall_AIR.swf/coolwall/messagebroker/
amf'] messageId=8E8E8B57-66F0-D797-2B5E-137734E88D9C type=fault 
bubbles=false cancelable=true eventPhase=2]

It is immediately obvious that the url is not correct. The host name 
and port is missing and even the first letter C is missing from  .swf
file name. It should have read http://localhost:8080/coolwall/
messagebroker/amf but apparently the AIR application is using the  .swf
file name minus the starting Capital character as the host name 
and port number. 

I use a program called ServiceCapture to capture the network chatter 
and it confirmed me that the host name and port number is indeed 
wrong. I mean it could also be a faulty debug trace statement but 
this proofs that the generated URL when using AIR and LCDS is wrong. 

In the Adobe Flex Builder Jira bug tracking system there is an issues 
which has been closed a couple of month ago and dismisses it as an 
error of either LCDS or AIR. The workaround is handcoding the exact 
URL in the remoting-config.xml file which is ofcourse not very 
sensible. I cannot judge which product is the one to blame as I lack 
the knowledge to do so. 

So does anyone (Adobe?) know which product (FB, AIR, LCDS?) is faulty 
and when it will be fixed. Thank you very much.

RE: [flexcoders] Re: LCDS - Express, how to change database connection

2008-02-13 Thread Jeff Vroom

Yeah, the approach used by the samples is designed so they are easier to
run on any app server.  Sounds like you know the right practice, but for
others who might be reading this for production use, I recommend using a
data source using a connection pool which requires app server specific
configuration.  That also keeps the connection info out of your code.

RE: [flexcoders] Re: Flex Data Management and container's UserTransaction

2008-02-13 Thread Jeff Vroom

Hi Shailesh,

 

I'm not sure what the problems are...  It sounds like you are using the
DataServiceTransaction.begin() and commit() methods yourself (the other
way this can be used is if you call the
DataServiceTransaction.getCurrentDataServiceTransaction() call from
inside of an assembler method such as createItem).  When you call
begin, if you specify useJTA=false I think that when you call commit()
on the data service transaction that those calls should go out no matter
what.   By the time this calls is made though, we will assume that the
changes you are telling us about have been applied to the data base and
either have already been committed.  It could be that you are calling
commit() just before the transaction has been committed?The part
that could go wrong there is the refresh fill process.  If you call
createItem() and then commit(), the commit will go through each
managed fill and potentially re-execute those queries to pick up the
newly added item.  If this fill call re-queries the database so it does
not see the change applied, it would not refresh it properly.

 

It might be that in one mode you are using the HibernateAssembler picks
up the same session and so sees those changes and in the other mode is
picks up a different session?  I'm not sure... if you still have
questions and can generate a server debug log for the problematic case
I'm happy to take a look.

 

Jeff

those
  changes and cancel those changes.
  
  
  
  For 1), when you are also using Hibernate, the hibernate assembler
will
  register a hibernate current session context class. The goal of this
  class is to ensure that we create one hibernate session for each JTA
  transaction we create for DMS and commit/roll them back in sync. 
Going

RE: [flexcoders] Does the LCDS HIbernate Assembler override fetch joins in HQL queries?

2008-02-11 Thread Jeff Vroom

I don't think LC DS is doing anything funky to override how hibernate
does the query.  We just are accessing the cat.kittens property to
pull out the identities of the kittens even with lazy=true.  I don't
know enough about hibernate to know how to get it to query kittens and
cats in the same select statement.

 

Of course in 2.6 (now in beta) we have the load-on-demand and page-size
properties you can set on the association tag so we avoid fetching
cat.kittens altogether until it is accessed on the client.

I am working with a bunch of named hql queries in Hibernate and it
seems to me that no matter how I write the query the properties are
still lazy loaded via my associations in the destinations files.

For example if I create a query,

select cat from Cat cat left join fetch cat.kittens 

kittens will still be lazy loaded if I have my association between cat
 kittens as lazy. The explicit fetch in the query is ignored.

I would be interested to know if anyone else has come across this
limitation?

RE: [flexcoders] LCDS and triggers, auto inserts or updates of timestamp columns

2008-02-11 Thread Jeff Vroom

One approach which works well for this type of thing is where you query
the values after you've done the update or insert and just populate the
changed properties in your instance.  LC DS lets the assembler modify
properties which are not defined on the client.  The most common example
is that you often set identity properties in your createItem method
after they are assigned in the database.  You also can do this for
version properties which get updated on each change though and certainly
a last modified timestamp would work this way.  In your createItem
method you do not need to do anything other than updating the property
in the instance passed in as it picks up any changed properties.  In the
updateItem method, you do need to ensure the changed property is in the
changes list passed to your assembler (or just add it if it is not).  

 

Since you are using the hibernate assembler, you'd probably need to
sub-class the hibernate assembler and put this logic into the subclass
after performing the create/update using the super class.  

 

The other way people use triggers is to modify rows or columns that
store data for unrelated objects... for that you'd have to use the
DataServiceTransaction api in Java to mirror what is being done in the
database if you want clients to track those changes.  Unfortunately that
means that you have to mirror the trigger logic in Java.   There's no
easy way that I know of to have the trigger notify the Java code so this
can be done automatically.

Should I expect to run into a bunch of DataService conflicts with
this or are they safe to use. I am not thinking about anything too
crazy, even just basic timestamp updating would be nice to implement

RE: [flexcoders] Re: Remote Object Security

As an additional level of security, you can set up your
services-config.xml to create a destination that REQUIRES SSL
(my-secure-amf or whatever) - this goes to an entirely different
servlet-mapping than normal remoting requests that will fail requests
not using SSL.  Combined with your SSL cert, that's some pretty good

RE: [flexcoders] Re: PopUpButton issue

Scott,
 
Gotcha. Don't know how it could be considered to be closed when the only
thing we've got is a hack to work around it.  But be that as it may, I
would think/hope that this is getting the attention it deserves..

I was able to make it happen by have a PopUpButton

This defintely must be resolved before Flex 3 is
released.  Can't have something as generic as a PopUpButton failing and
requiring a workaround.  Yes it is true that there were other issues
with the PopUpButotn component, however right now this component is
effectively broken and I would hope it doesn't assume the category of a

RE: [flexcoders] Re: Setting combobox selectedindex

You have to override the set dataProvider function and others - have you
actually looked at Ben's code? When the dataProvider is updated, the
'set value' does not. A comparison between the dataProvider value can be
done and set selectedIndex accordingly. Believe me, it works - I'm using
it in production apps now.

I have to say, it would be nice to have this feature part of the core
Flex ComboBox implmentation, so that selectedItem can be set as well as
gotten. The problem is, of course, that you don't know what sort of data
type is in the data provider and so comparison is more difficult.  I
dealt with that by requiring my data types in the dataProvider conform
with a custom interface, and thereby make comparison easy.  I suppose
might be other ways to accomplish the same thing.

RE: [flexcoders] Re: PopUpButton issue

Joann,
 
I understand the constraints of time, release dates and such.  It is a
real pain, though, that a component that is pretty darn useful needs a
hack-y workaround just to continue to use it - and that means code
refactoring in a number of places, because I've gone to it alot. :(

The original bug is Deferred and Closed. This doesn't mean it
won't be fixed, however. It is deferred for this release of Flex 3
(which is coming to an end), but, it can be reopened for our next
release. So, you didn't need to file a new bug. However, you should vote
on the original one that is deferred. Since this bug is a regression
from  from Flex 2.0.1, we will probably fix this in the future. We just
didn't get the time during this release :(

I'm still trying to identify the exact steps to re-create but suffice to

component refuses to work.  I'm doing things declaritively, with MXML
like this:

mx:PopUpButton x=500 y=10 label=Add Company width=220

This is pretty vanilla code - of the type I have not seen issues with

works fine in a test AIR app not using modules. Any input appreciated.

Try indexToItemRenderer().  Keep in mind that if you are

[flexcoders] TabNaviigator tabBar index doesn't update on selectedIndex change

2008-02-01 Thread Battershall, Jeff

I'm using Flex 3 Beta 3.  I have a TabNavigator component where the
children are created dynamically from a Repeater.  When the dataProvider
of the repeater changes, the tab labels update accordingly, EXCEPT the
tabBar index of the component doesn't visually update.  I would just set
myTabNav.tabBar.selectedIndex = whatever, except that the tabBar is a
protected member.

I can work around this by extending the component (I think) but I
shouldn't have to do this - perhaps I'm missing something on how to best
approach it.

The best method I've found is to just remove all native

showChrome= false to your WindowedApplication ).  From there, it's
pretty trivial to mimic native functions.  Here's the ones used for beta
3 (they changed it, so googling around gets confusing): 


this.nativeWindow. minimize( ); // minimizes the window

this.nativeWindow. close(); // closes the window

this.nativeWindow. startResize( ); // call this within a

All assuming this is the current window.

These are Java options you set on the Java command line - not specific
or related to LC DS.  Usually in your server's startup.bat or something
it lets you add additional Java args so that's where these would go.

RE: [flexcoders] DataServices (Service.Data.General) error...should I be concerned?

2008-01-28 Thread Jeff Vroom

Yeah, it looks like this error occurs when you have an association tag
for a property (in this case a one-to-many or many-to-many) and there is
no corresponding property on the Java class which is getting serialized
back from the client.   Unfortunately the diagnostics for that error
don't tell you the destination or the property (which I just fixed in
the code) but if you turn the debug log on, you'll see what items are
being modified in the batch and can probably figure it out from that.

It doesn't seem to be crashing things, but i figure it can't be good. 
My only thought is that this could be caused by some transient
properties that are in some classes, but are referenced in my

destinations, but perhaps we have caused problems with this.

I would be interested in how I could dig deeper into what is causing

RE: [flexcoders] Destination not found error with liveCycle DS and Flex

2008-01-26 Thread Jeff Vroom

There are two ways to fix this:

 

1)   change your compile options to include the -services
WEB-INF/flex/services-config.xml so that the destination configuration
and channel configuration is compiled into the SWF.  This allows you to
use the symbolic destination id in your client without specifying a URL
to connect to the server.  This is a flex builder configuration option
or set on the command line if you use that.  It is set in
flex-config.xml if you use request the mxml from the browser. 

 

2)   Define a ChannelSet on the client in MXML or ActionScript and
set the channelSet property of your service to this channelSet.  This
allows the service to contact the server to pull down the destination
information at connect time.

Oh, and in regard to AMF polling and your connected state, this channel
issues poll requests over HTTP on an interval. If your server is
unreachable, the next poll request that is sent will fail, triggering
the channel to move to a disconnected state.

If you enable client logging (mx:TraceTarget and a debug player) you
should be able to see log entries for the channel issuing poll requests
and when one of these fails, an entry stating that the channel has
stopped polling.

However, using RTMP it works fine.

Also, is there a way to distinguish a disconnect from when the server

wondering if the temporary storage of this information is encrypted in any way. 
 We are looking at creating an AIR application that will take credit cards.  
You can imagine the regulations around that.  So I was wondering if there is 
any documentation as to the details of how the disconnected sessions are 
implemented in AIR.  So far I have not been able to find anything.  Any help on 
this would be greatly appreciated.

How about encrypting them in the application?
 
If the application is disconnected, you won't be able to verify the cards. Most 
websites don't keep credit card details (unless the user specifically allows 
it) so credit cards and a disconnected application sound like a challenge. I 
can't remember the last time I gave credit card info that wasn't verified on

From what I have figured out… Flex stores to a local db file that is 
accessible to any other flex app that is running on the local machine.  Not 
secure.  The only way you are going to get it to be secure (from my 
understanding) is to encrypt it yourself and develop a security routine 
yourself.  Syncing with the server is either handled on your own, or if you 
use liveCycle or some other DTO with logic that does this automatically.  
There are some good tutorials on doing this with Java and LiveCycles, but I 
don’t have much access to my server and don’t know how to tell if I have 
LiveCycles installed (or knowledge of Java) so I have been writing a custom 
sync routine that happens whenever a record is saved that sends all unsynced 
records (“UPDATED”, “DELETED”, “NEW”) to the FDS gateway into a ColdFusion 
Service.  I am also going to use GUIDs to insure that the info is unique.  
You’ll want to clear the CCs out of your local SQLite db
 manually if you intend to store it the way I’m doing it.
 
If I’m wrong someone correct me.

RE: [flexcoders] Re: Flex + Spring + Hibernate - Lazy=true

2008-01-11 Thread Jeff Vroom

We haven't released the source for blazeds yet but it is coming.  It
does not contain any AS source generation but I think that is easy to
layer on and there are a bunch of decent implementations out there.
There is better support for customizing the serialization process in
blazeds (improved over 2.5.1).  The beta for blazeds has some of this
but we are adding even more between beta and the release.  

 

Implementing lazy loading is a bit of a pain with hibernate if you have
to do it using remote object.  There are two major issues:

 

1)   the class names of the generated wrapper classes used by
hibernate mess up the mapping of the class names used to find the right
AS class.  This one is easy to get around with this PropertyProxy
mechanism.   In fact, LC DS contains the source to a PropertyProxy
implementation (HibernatePropertyProxy.java) which you can use with
remote object to strip the generated class name off before
serialization.  This has the side effect of returning empty versions of
all non-loaded lazy properties which brings us to problem 2).  Note that
hibernate has different mechanisms for doing the lazy loading.. it can
do byte code modification but I haven't used that technique so I'm not
sure how it works here. 

2)   If you did not fetch a property with lazy=true in hibernate
before the session is closed, the attempt to access that property during
serialization fails with the session closed error.  To get around
this, you can make sure you access all properties you need before the
serialization.. this is the approach used by LC DS but because it has a
model of the association properties, you don't have to code it up
yourself.  It is done by the assembler so it is automatic.Another
hacky approach is to put a servlet filter in which opens up a hibernate
session before calling the MessageBrokerServlet, then close the session
once it returns.  That means you lose control over the hibernate
sessions in your application and you have a transaction which is open
for the entire duration of the request which is not very flexible.
There might also be performance problems if you have a
session/transaction open while you are doing I/O.  Not sure that will be
a problem but these are the reasons we went with the prefetch
mechanism in LC DS's hibernate assembler.

 

 In terms of the issues with hibernate in 2.5 and earlier versions, one
of the trickiest things is that you need to make your
data-management-config.xml match up with the hibernate config.  We're
hoping to get a chance into a future version which makes this not
necessary since the configs are pretty similar.  You also need to do the
AS code which matches the Java code yourself (or use a 3rd party code
gen tool).

instances if the same object, and the need to manually write 
actionscript counterparts of java objects. IFAIK, there no tool for 
automated generation AS3 classes out of java classes in BlazeDS. For 
big projects with permanent changes to the objects it is pain to 
manually maintain both AS3 and java obejcts sync.

it would be nice to implement all these features in open-sourced

You can use the method DataServiceTransaction.updateItem(..) to update
association properties as well.  You need to create an instance of the
parent object, fully populate the association property with the new
values, then specify the property name (or names) you changed in the
changes parameter.   You can supply null for the previous item of

RE: [flexcoders] Re: Manual refresh nested collection in LCDS managed object

2008-01-10 Thread Jeff Vroom

If you make a change to the collection property on the client side, we
queue an update message for the parent item of that collection.  This
update will send down the entire collection, then push it to other
clients even if you only added or removed one item from the collection.
If your collection property is lazy=true we only push around the ids
of the elements in the collection.


If you change a property of an item in a collection and that collection
is a managed association, we only send the update for the item in the
collection.  The parent item is not affected.  

 

This does make collection properties somewhat inefficient when dealing
with large collections.  We have an alternative way of doing updates to
collection properties coming out in the next release where we send
around incremental changes. 

 

The ArrayCollection.refresh method is (I think) just about updating the
client side sort and filters.  It won't go back to the server.  You'd
have to call getItem or fill again for the parent item to refresh the
child collection's membership.  To refresh individual items in the
collection you can call getItem on them.

I am curious to how this works internally. If I make a change to a
collection (or an item in the collection) on the actionscript side,
when that change is made on the server does the whole collection get
refreshed OR just the single object that I made the change to.

Also, I am assuming that when I call someArrayCollection.refresh() on
the client that this does NOT signal a refresh of data from the
server. I would have to do something more substantial to actually
signal a reload of the current data from the server (like change some
data)... correct?

I guess I am trying to figure out the expected behavior when trying to
managed objects/collections on the client with autosync vs. manual sync.

RE: [flexcoders] Lazy Loading on Tree Component with LCDS

2008-01-06 Thread Jeff Vroom

On second thought, this will be trickier than I thought.  One problem is
that you need to put a NotPendingCollection as a property in your
model so you get hierarchical collections which don't throw IPEs.  This
isn't too bad but you can't then use static data binding expressions to
forward events from one collection to the other so you need to write a
bit of code and probably need to make that property read-only or mark it
as [Transient] so it is not managed.   This approach also is going to
push the 2.x Tree implementation since it will have to respond to
collection change events to dynamically update the display.   If you can
use the Flex 3 approach Alex described, that would be much easier and
work better.

I have an approach that might help with the 2.x Tree.  It is a subclass
of ArrayCollection you can use to suppress ItemPendingErrors which you
can get here:

 

   http://www.jvroom.com/NotPendingCollection.as

 

You provide it a source collection and this collection will either be
empty or fully populated... it won't throw ItemPendingErrors.   You can
use it with lazy loaded associations or paged collections but if you use
it with paging, the first time someone access an item, it will page in
the entire collection (unless you set startIndex/maxIndex as described
later).   It is still a bit experimental but let me know if you have
problems with it as the code is not too complicated.   

 

To use it you'd put this between your tree and your filled/associated
collection:

 

!-- the data as it comes from the server... in this case I pass
this to fill --

mx:ArrayCollection id=streamData/

!-- a view of the data that does not throw IPEs
(NotPendingCollection does not do sorting) --

NotPendingCollection id=notPendingStreamData
sourceCollection={streamData}/

 

 ...

 

  mx:LineChart dataProvider={notPendingStreamData}

 



It also has a startIndex and maxIndex parameters so your collection can
expose a sub-region of the paged collection.  This allows you to use
this more efficiently if the underlying collection is paged.   I've done
some testing on this using a chart (which also does not handle item
pending errors) but haven't tested it with tree.  In my sample, I hooked
up the start and max index to the visible regions of a data grid and
then have the chart display the visible data as you scroll in the grid.

RE: [flexcoders] Configuring message channels - RTMP

2007-12-18 Thread Jeff Vroom

The ChannelSet should send a disconnected event when the client detects
from the server that it has been disconnected.  You should get immediate
notification for RTMP channels since we deliver this even when the
server closes the client's connection.  

 

I don't see how a firewall would affect this unless the RTMP connection
itself failed to be made through the firewall.   You might be falling
back to RTMPT which is a polling implementation using the same port but
I think that RTMPT though would also deliver the disconnected event in
the same way as RTMP.  

 

If you have an AMF/HTTP channel defined as a fallback, it might be that
you are using that channel now instead.   For those channels, we rely on
the app server's session to track the connected state of the user.   The
session will typically not timeout though on a polling channel because
the poll requests keep it alive.   Instead, you have to set a
subscription-timeout on the destinations you are subscribing to.  Once
your subscriptions timeout, your consumer's subscribed property will
get set to false and polling will stop so your session can eventually
timeout.  You can watch that subscribed property to detect that case.

2007-12-18 Thread Jeff Vroom

When you are returning a property of an object which is declared as an
association in your data-management-config.xml with lazy=true, you can
just create an instance of the referenced object and only populate its
identity properties.   Since the referenced object also has a
destination defined, in that destination you specify the identity
property names used for objects of that type.  These are the only
properties DMS will look at on the referenced object.  

 

We do ship the source to the HibernateAssembler though it is a bit more
complex given that hibernate has lazy fetching property of its own.

RE: [flexcoders] LCDS, FDMS, Custom serialization of lazy references

2007-12-18 Thread Jeff Vroom

You do not need to use the Externalizable interface to do lazy
associations with DMS.   You just need to follow the normal rules for
mapping Java to AS classes (public read-write properties must match,
RemoteClass(alias=...) needs to be set, zero arg constructor).  

 

We exclude the lazy=true properties from serialization... neither the
get nor the set method will be called on those instances during
serialization itself.Instead, in the message sent across the wire a
separate header is used to store the referencedIds for each
lazy=true property.  These headers are then used to repopulate those
properties on the client.

RE: [flexcoders] Flex Data Management and container's UserTransaction

2007-12-13 Thread Jeff Vroom

There are two use cases where we DMS will use the UserTransaction.   

 

1)   When your assembler has use-transactions=true, and you commit
a change or batch of changes, the DMS code will start a transaction
before calling your createItem, updateItem, and deleteItem methods.  If
any of those get an error, the transaction is rolled back and all of the
changes are put back into the uncommitted list on the client.   If they
all succeed the transaction is committed and the changes pushed to other
interested clients.

 

2)   If you use the DataServiceTransaction api to push changes from
the server, when you call begin you can pass in a value of true which
causes the DMS stuff to start a JTA transaction in that call.   When you
call commit, the JTA transaction is committed if the setRollbackOnly
call was not made.   This is just a convenience if you happen to have
some JDBC code which is updating the database.  You want to both commit
those changes and push the changes to other clients or rollback those
changes and cancel those changes.

 

For 1), when you are also using Hibernate, the hibernate assembler will
register a hibernate current session context class.   The goal of this
class is to ensure that we create one hibernate session for each JTA
transaction we create for DMS and commit/roll them back in sync.  Going
forward I'd like to offer another way to do this so that we can more
flexibly integrate with other ways of using hibernate sessions.

[flexcoders] ProgressEvent.bytesTotal not populated?

2007-12-11 Thread Battershall, Jeff

I've built at AIR app that supports application update, but I'd like to
show the user the progress of the updater download. For some reason, the
ProgressEvent.bytesTotal just isn't coming over the wire. bytesLoaded
sure is, just not bytesTotal.  It isn't as though this is some tiny
file, either - we're talking about 4MB, so the player *should* have time
to get this info.

RE: [flexcoders] Re: DataServiceTransaction auto-refresh issue

Each Java class needs to be serialized from ActionScript.  Right now,
this means exposing all properties using public get/set methods or with
a public field.  Without a setter, it is hard to know exactly what field
to set when we deserialize a class.

Long story short, the id property of my server-side object was NOT
writable. This is intended as it ties to the DB identity and is either
set during construction or via hibernate during insert/retrieval to/from
the DB. 
I changed the setId() method to public, and everything works fine -
updates are pushed to the client and my DataGrid updates accordingly. 

Though I question why this has to be writable? I want it to be read-only
to prevent tampering. Why must it be writable??? 

According to the Live Cycle docs: 
A Data Management Service destination contains one or more identity
elements that you can use to designate data properties to be used to
guarantee unique identity among items in a collection of data. 
So as long as I set the identity, shouldn't LCDS need only the ability
to read it for comparison purposes??? I know it is getting set properly
as I can debug and see it prior to serialization. 
Thoughts???

RE: [flexcoders] Re: RemoteObject silently throwing #1009 null object error

Oh, so these errors occur before the server even gets the request?   In
that case, it could be the get methods of the parameters to your
remote object that are causing this error during the serialization
process.  You won't be able to step into this code since it gets called
from native player code when the player tries to write the data into the
socket.  You should still be able to set breakpoints in your own code
though.

2) If my error is happening as the message gets created is that not
AMF serialization rather than de-serialization? Do I have that the
wrong way up?

I don't see why a set method would be called when serializing, but I
can understand if it were deserializing. Either way this is an

RE: [flexcoders] Re: DataServiceTransaction auto-refresh issue

Oh interesting I haven't run into this case before, but I think we do
still need the ability to set the property on the AS side at least.
When you create an item on the client, it might have a null or empty id.
When you commit that change, the server typically assigns an id.   The
client gets returned a new instance of the same item with the populated
id which then need to copy over into the original instance.

RE: [flexcoders] DS - Data synchronization between 2 destinations?

2007-12-07 Thread Jeff Vroom

We are working on improving the ability to do these types of
master/detail relationships in future LC DS versions with a single
destination.   Using one destination is obviously how you'd like to do
it but you do run into some performance problems for large collections
and object graphs with how it is implemented today.   In the future
we'll have additional metadata to specify on association properties (at
least) which let you specify one or more properties are unfetched until
the client tries to access them.  

 

I take it you are turning off auto-sync so you can use the paged fill
stuff -i.e. the fill methods which return a page at a time?   (We hope
to also remove that limitation in the next release as well).

 

The simple answer for keeping data between two destinations in sync is
that in your assembler's updateItem method for one destination you use
the DataServiceTransaction.updateItem method for the other destination
(or similarly for createItem and deleteItem)

 

But when auto-sync is turned off, clients using that destination won't
receive those pushed changes.   You can however use manual
synchronization.   Clients can subscribe to one or more subtopics or use
a selector expression which specifies which messages they want to
receive.  Clients or server code which publishes changes can specify
which subtopics those messages go to.  

 

Here's a snippet which shows you subscribe manually for a destination:

 

personService.manualSync.producerDefaultHeaders =
{a:4}; // used for selector expressions

 
personService.manualSync.producerSubtopics.addItem(grouptopic);

 
personService.manualSync.consumerAddSubscription(grouptopic, a IN
('3', '4', '5'));   // subscribes both to a subtopic with a selector
expression

personService.manualSync.consumerSubscribe();

 

The DataServiceTransaction class also has the ability to set headers and
subtopics which its changes are published to.

Subject: [flexcoders] DS - Data synchronization between 2 destinations?

 

Hello,

I run into a problem. I'm using LC Data Services with two destinations:
Customers and Customer. First one is used to fill datagrid with
basic customer information like name, city, the second one to
get/update/create specific customer. I decided to split this into two
destinations because there are 30,000 or more customers so destination
Customers uses custom paging (with startIndex, number of rows) and
there are many more properties of each customer than name, city.

So, when user double clicks in the data grid form displays and
destination Customer getItem is called to fetch full information
about this specific customer.

So far so good. It works flawlessly. BUT! because i'm using paging to
fill datagrid i disabled caching and autoSync:
cache-itemsfalse/cache-items
auto-sync-enabledfalse/auto-sync-enabled
in Customers destination configuration.

How can i make destination that fill datagrid aware of changes made
through other one? I thought about using subtopics, but as far as I
know theses are destination specific so no joy.

Maybe I should do all of this using only one destination? but what
about getItem in assembler? I cannot use it once to get full customer
data and the other time to upadte specific row in datagrid (getItem
would be used to refresh particular row in case of update, wouldn't it?)

Im using plain java for assemblers, services (no hibernate, etc.). 

I'm looking forward for any suggestions, it is quite possible I'm
making a big conceptional mistake because i just started using DS (and
i find it amazing).

If you are using clustering but don't have sticky-session load balancing

mx:TraceTarget includeTime=true/ works well.  For the server, I like
turning on Message.* and Service.Data.* patterns.  I can help you

point in the logs where a specific change is not pushed.  

 

I'll also email you offlist a test jsp file which dumps out the server's

the server has and which clients are subscribed to which.

UNLESS we set up destinations for each of our collections and then set
up associations for these collections.  We are using annotations with
Hibernate, but I seems to remember that we still need to do this step

RE: [flexcoders] Need Help with DataServices pushing data to nested collections

2007-11-20 Thread Jeff Vroom

It sounds like you do not have association tags in
data-management-config.xml for each of these relationships and so are
using the hierarchical values approach for managing the hierarchical
data.   This approach can save hierarchical stuff to hibernate fine if
your hibernate associations have the save-update flag - since
hibernate cascades the save operation down the object graph.. it will
save the employee even when the change is made to the company.  This
approach also can push these changes to other clients but only when you
modify them via the parent - i.e. in this case, you'd have to modify
company.departments[i].employees and only another client that had
retrieved the same company would see the new employee get pushed to it.


 

If you are doing a query to get the employees directly, data management
won't know it is the same employee and so those clients would not get
that pushed change.

 

For this more granular approach, you need to define the associations in
your data-management-config.xml to match the associations in your
hibernate configuration.   That way DMS knows the ids of each entity,
the data types and stuff like that and can keep everyone in sync.

collections. Here is an example:

Company contains a collection of Departments - added Departments get 
pushed properly to the clients as expected.

Department contains a collection of Employees - added Employees 
get recorded in the database BUT DONT get pushed to clients

Employee contains a collection of Schedules- added 
Schedules get recorded in the database BUT DONT get pushed to the 
clients.

Currently there is only one destination for Companies which then (as 
I understand it) should manage it's child collections. As you can 
see the management seems to be working OK, but not the data pushing 
once we get more than one level deep in the collections.

Is there something that we may be missing here in our setup or 
assumptions? Any ideas would help as we are on a tight schedule to 
finish this part of the app before the Thanksgiving break 
(tomorrow!!) If you need to see our code let me know and I will paste 
some. Of course, I am assuming that there must be a way to get data 
pushing to work with deeply nested collections.

RE: [flexcoders] LiveCycle with multiple data services failing...

2007-11-20 Thread Jeff Vroom

I am not sure why this is failing, but you might check to see what
configuration if any is getting compiled into your SWF.  Check the
static variable: mx.messaging.config.ServerConfig.xml.  If you trace
that out, it should contain a subset of the configuration found on your
server.   It gets it through the compiler's -services
services-config.xml option.  It sounds like maybe you are compiling
against a different version of the config that only has that one
destination?

 

The other approach DS has for getting the server's configuration is by
loading it from the server at connect time.   It will do this if you a)
do not compile in the configuration and b) define your channel set on
the client so that the client knows which server to talk to.  In this
case, the ServerConfig.xml variable gets populated only after you
connect.  Again, it would be interesting to see what is in there as that
might help you track down how you are getting incomplete configuration.

 

I'd also recommend turning on the mx:TraceTarget/ option as that logs
some good debug info the flashlog.txt (including the config that is
being used).

Subject: [flexcoders] LiveCycle with multiple data services failing...

 

Hi,

I have a strange problem - hopefully someone might be able to figure
out what's wrong...

First, I'm using Flex 3 beta (Eclipse 3.2+WTP1.5), LiveCycle 2.5,
JBoss 4.02.

So here's what I do...

I use the Flex 3 'create application from database' (if you've not
used it yourself, don't give up on me - the problem is almost
certainly unrelated to this step!) to create a flex 3 livecycle app
from the wizard. This runs fine!

I then run it again, against a different table. Again, the second app
is fine.

But when I try to combine the two applications (obviously renaming
variables on both sides to avoid a clash), one of the dataservices
runs absolutely fine but when I try to use the other, I get:

'Destination 'SIM_USER_REPORT_PAGESJava' either does not exist or the
destination has no channels defined (and the application does not
define any default channels.)'

But this destination is defined in the same data-management-config.xml
as the one that is working - and they're both using the same channel -
so I know that channel both exists and works!

Any ideas why the second service won't work when combined with the
first? I've listed the data-management-config.xml below in case it
helps...

Thanks,

Jamie.

RE: [flexcoders] Need Help with DataServices pushing data to nested collections

2007-11-20 Thread Jeff Vroom

First off, did you know about
resources/config/data-management-config.xml?   It is sort of like our
asdoc for configuration. 

 

The below scenario should work without associations in
data-mangement-config if the data structure forms a tree but won't
work if it is a more general graph.  If you use hierarchical values, we
basically just send around complete serialized versions of the top level
object (e.g. the company) for any change to any sub-object so it can get
expensive for deep or large graphs.  With the managed associations
approach we will send over updates for individual items in the graph.
With lazy=false, the server to client stuff will be the same but with
lazy=true we send over just a slice of the graph at a time and fetch
referenced items individually so it is more flexible too.

Subject: Re: [flexcoders] Need Help with DataServices pushing data to

Thank you.  I think I understand, but just in case here is a scenario of
what we are doing.

 

We get our list of companies from a fill operation so now we have a data
managed collection companies.

 

var departments : ArrayCollection = companies.departments;

//to add an items

departments.addItem(deptartment);  //this works fine and pushes fine

 

var employees : ArrayCollection = department.getItemAt(0).employees;
//we usually get to this using a selectedItem from a DataGrid

employees.addItem(employee); // this add to db but doesn't push

 

var schedules : ArrayCollection = employees.getItemAt(0).schedules; //we
usually get to this using a selectedItem from a DataGrid

schedules.addItem(schedule); // this add to db but doesn't push

 

I am guess that what you are saying is the above example will not push
UNLESS we set up destinations for each of our collections and then set
up associations for these collections.  We are using annotations with
Hibernate, but I seems to remember that we still need to do this step
when using annotations. Would you say that in general if you would like
to take full advantage of data pushing it is a better idea to use a
manage association approach rather than the default hierarchical
approach?

 

Is there an API for the data-management-config file?  I know we have had
questions about what tags go where and the dev guide didn't seem to
specify everything.

 

Thanks for your help.  We LOVE data services... when understand it and
get it working!!!

hibernate cascades the save operation down the object graph.. it will
save the employee even when the change is made to the company.  This
approach also can push these changes to other clients but only when you
modify them via the parent - i.e. in this case, you'd have to modify
company.departments[i].employees and only another client that had
retrieved the same company would see the new employee get pushed to it.


 

If you are doing a query to get the employees directly, data management
won't know it is the same employee and so those clients would not get
that pushed change.

 

For this more granular approach, you need to define the associations in
your data-management-config.xml to match the associations in your
hibernate configuration.   That way DMS knows the ids of each entity,
the data types and stuff like that and can keep everyone in sync.

That is very strange.  Can you reproduce that with the server debug
logging enabled on the server for the Message.* and Endpoint.*
patterns enabled (in WEB-INF/flex/services-config.xml, set level=Debug
and make sure those patterns are in the tags below).  

 

Unfortunately the error does not include the message which is causing
the error.  It should be either a batched or transacted type of
message.  The body of those types of messages is supposed to be an
array of DataMessages but somehow we are getting an untyped ASObject
in there.

RE: [flexcoders] RemoteObject call does not get through if called by a Module

When I have seen this before, the problem is because the LC DS swcs
(rpc.swc and fds.swc) are being linked into a module and not the main
swf.  It may be that if you put the RemoteObject references into the
main swf, that by itself is enough to make those classes get linked in
there and so that is why it works.  If you put some references to those
classes in the main swf, it may also just then work in the module as
well?

  But the assembler doesn't know what fills are active, either.
  Or am I missing something? The assembler can keep track of a

  notification when the fill is no longer being used (e.g., when
  the client goes away)?
 
 Yes, this is the case.  The auto sync mechanism is what keeps track 
 of which fills clients are looking at specifically.  You would have 
 to duplicate this logic and it is not trivial.  To solve this 
 generally is a bit tricky - you need to watch when fills are made, 
 associate them with a session and remove that when the session 
 expires.

It's a little worse than that, because you could have multiple
sessions using the same fill, right? So you would need to keep
track of which sessions reference a fill and only remove the fill
when the last session had closed.

I imagine that clustering only adds another set of problems on
top of this too. Is there an example of using manual sync in
a clustered environment somewhere?

  In my application, the fills have a sort value, meaning
  that the new item could be in different positions in
  different fills anyway, so what I think the client should
  do is to just start the fill over again when an item is
  created. How would the assembler notify the client that
  it should do that? (That is, how do I get something
  similar to a refreshFill method returning EXECUTE_FILL
  in the auto-sync case?)
 
 Again, we just don't have a great way to refresh an entire
 sequence when auto sync is false.  It sounds like you really
 need the auto-sync=true with the paged fill support. 

Desperately :-) What I'm thinking of doing is have the new item
added at position 0, and have the client check, when an item is
inserted at position 0, if the item is less than or equal to
(according to the sort being used) the item in position 1. If
it's not, the client would just call the fill again to get the
new item in its proper position. Does that make sense?

RE: [flexcoders] conflicts resolution for flex data service and hibernate

Do you maybe have cascade=save-update set on the survey.questions
association?   Removing that might help.   This survey.questions also
would typically have inverse=true where question has a survey
association that points back to survey.   

 

It seems like for some reason hibernate is trying to persist the
survey.questions property when it changes.  It should rather ignore
changes made to that property (which it will do if inverse=true is
set).  Things behave better with a 1-many association when you use a
bi-directional association where the many side has inverse=true.

I have two classes, Survey and Question. Both of them have version 
attribute. Class Survey reference a collection of Question.

When I add new Question object into the collection reference in Survey, 
then I commit. e.g. 

surveyServiceervice.fill(surveys, survey.all, []);
var survey:Survey = surveys.getItemAt(0);
var question:Question = new Question();
survey.questions.addItem(question);
surveyService.commit([survey], true);

in my database, I see the new question object persisted, with foreign 
key pointing to the survey. I also see the question has a version 
number of 1. 

Here is my headache: all the other question objects in the 
survey.questions have their version number increase by 1. But they are 
not reflected in the client (browser) side. This makes all my client 
side data obsolete.

I wonder whether this is the supposed behavior of hibernateflex? if 
not, what configuration attributes I need to take care of?

Thanks a lot!

RE: [flexcoders] Re: RemoteObject call does not get through if called by a Module

This does seem strange.  There are a few tricks you can use to get more
details.  On the server, the debug logging configuration is set via the
WEB-INF/flex/services-config.xml file (set level=Debug and the
pattern tags below control which patterns are logged).  The
Endpoint.* pattern will show the details of the serialization process
including the alias sent over from the player.  

 

The other thing that would be interesting is on the client side to check
the aliases registered for these Message classes.  If the server
responds with an instance of a class like
mx.messaging.messages.AcknowledgeMessage and there is no alias for that
class in the SWF, it will come back as an Object and you get those
type casting errors.  There is the describeType call in the player
apis which lists the info for a given class and the
mx.utils.ObjectUtil.getClassInfo method uses that to return this info in
a form that is easier to use from ActionScript.

 

When we build the swcs such as rpc.swc and fds.swc which include message
classes, we use a trick so that any swf that links against that swc
should include versions of the message classes.  Their aliases should
also get registered at that time. 

 

I believe that aliases are visible across the player instance and not
isolated for a module so it might be possible for a module to get loaded
that registers an alias for a class loaded via another domain.  That is
one reason it is important to ensure only the main swf links in the
Message classes.  The other swfs should treat those swcs as external
libraries.
