[flexcoders] Re: ADG/DataGrid prevent render even from firing immediately on propertyChange
You might try enableAutoUpdate and disableAutoUpdate on ICollectionView, not sure if that has the desired affect or not. You could also put custom events in your model objects and manually dispatch collection events or call explicitly tell the grid when to update. --- In flexcoders@yahoogroups.com, tntomek tnto...@... wrote: Hi, Is there any way to tell the ADG to not re-render itself immediately after a propertyChanged even has been fired in the dataProvider? I have quite a wide row (lots of cells) and lots of custom logic that updates these dependent properties on each row. i.e. calculated columns. I am doing the calculations at dataProvider level vs labelFunctions. On each set function of one of my cells in the row I raise a propertyChanged event if the value was changed. Tracing through what the ADG is doing I'm finding that its re-rendering each time I raise this event even if its in the same row. Is there any way to tell the ADG to wait a few milliseconds in case another propertyChanged event comes in so as to render once instead of 10 times? If there is no ADG option what is the best pattern for this assuming I want to do this in my underlying dataprovider objects. Should I raise custom events and fake a itemUpdated once I know there are no more changes? I don't see a clean way to do this however since I never really know when I'm done, and using a timer or something of this nature seems like a major hack. -Tom

By looking at the logs I can see that the server side method (invoked via RemoteObject on the client side) never executes in more than two threads at the same time. What I mean is that if I fire 5 simultaneous requests to the method using RemoteObject from the flex side, and log when the method is executed and when it returns, I get something like this: 12:00:00 Method Executed 12:00:00 Method Executed 12:00:01 Method Exiting 12:00:01 Method Executed 12:00:04 Method Exiting 12:00:04 Method Executed 12:00:10 Method Exiting 12:00:10 Method Executed 12:00:11 Method Exiting 12:00:13 Method Exiting While on the client side I see that all the 5 invocations were fired at 12:00:00. As you can see, the method tend to take a while to run. But the big problem is that the log suggest that some queuing is happening on the server side, allowing only a maximum of two threads to run in parallel at any given time. I thought it could be a problem with the thread pool of the servlet container, but my Tomcat has the following configuration: Executor name=tomcatThreadPool namePrefix=catalina-exec- maxThreads=150 minSpareThreads=4/ So I guessed that the limit could be imposed by BlazeDS itself. But haven't found anything on the documentation. Of course, I could be wrong and the problem may be something else. Any ideas?

[flexcoders] LCDS Push API Problem
I have a custom assembler, that uses the interface approach, which returns an object with a XML property. When I open two clients and edit one through LCDS the other updates as expected. I then have server code which updates the same XML property and calls the newer DataServiceTransaction refreshFill(..., null, propertySpecifier) and again both clients update to the new XML property value. However, if I restart both clients and first update via the push API the clients DO NOT receive the changed XML property value. If I next update from a client, both change and from here on out they will respond to the server property change pushes. It appears to me that something is being registered when an object is updated via the assembler that allows it to respond to future server API property pushes. I need the push API to work even when no client updates occur. I should note that when using the push API I am only calling refreshFill with a propertySpecifier and am never calling updateItem. I'm doing this because the XML value is actually a compound property and changes depending on a given fill parameter (it happens to be a date window which I cannot predict from the other server code where the push occurs). Anyone have any thoughts?

[flexcoders] Does ASDoc process metadata tags?
I have classes that are marked with [Managed] and [Bindable] tags. Even though these objects do not extend eventDispatcher I can call dispatchedEvent, addEventListener, and removeEventListener on them. I assume this is because the compiler is wrapping the dispatch code around the object when it sees the metadata tag. This works fine in Flex Builder but when running ASDoc it serves up these calls as errors. Is there a flag I need to set for ASDoc to process the tags when compiling the objects?
[flexcoders] Data Binding to Paged Data (w/ LCDS 2.5.1)
Does anyone have any experience applying watch bindings to items that are paged and throw IPEs? I have a managed object that has relationships to other managed objects. I want to perform operations on the related items when they are pulled client side (from DGs or other view controls) and any time they change (from this client or another); so in the constructor I have: ChangeWatcher.watch(this, [auxUserData, techMinInc], onTechMinIncChange); Where *this is a managed object and techMinInc is a property on the related auxUserData managed object. This throws an IPE from ConcreteDataService and it's not catchable here. Must I first finger auxUserData, catch and handle the IPE before applying the watch? Or does anyone have a best practice approach to this type of problem.

[flexcoders] lcds / fds release collection problem
I have a flex 2 application where you can open tabs (of canvases) that display and edit managed data using lcds 2.5.1. The retrieved data is somewhat encapsulated to the UI tab so when the tab is closed I want to release the data to minimize the client memory footprint and data management overhead. The data is retrieved using fill() so to release I use (my DataService).releaseCollection(serviceArray). This synchronous call blocks for a long time and greatly increases the memory footprint. As an example a service array with a length of 127 objects took 48 seconds and actually increased 202,094 bytes just to release. The objects in the service array have several lazy associations; some of which have been accessed; some of which have not (based on paging from my DataGrid). Could there be a circular referencing problem? I am probably doing something obviously wrong but I can't figure it out and would appreciate any advice.
[flexcoders] Re: lcds / fds release collection problem
Unfortunately I already tried releaseCollection(.., true); and the results were the same. In my test scenarios there are no other references to the data outside the collection passed to releaseCollection. Beyond my test scenarios it would be possible to have multiple references in which case I would want the copies to be made and data maintained. Is it possible that my object's lazy relationships are causing excessive graph traversal during the release? If this is the case I'm wondering if I can test that by changing that relationship information in the data management configuration file even though the relationships still exist in my DB without causing any other unintended consequences. --- In flexcoders@yahoogroups.com, Jeff Vroom [EMAIL PROTECTED] wrote: Try calling releaseCollection(.., true); If you are releasing a collection which has an object which is still referenced on that client, DMS makes a copy of the instance.

It then appears that these are not cleaned up or released when the application B session is invalidated (must have something to do with application A still being open). Then when application B is restarted it tries to used the previously cached proxy but that session (and indeed the whole client who first requested it) has ended. All of my relationships or lazily loaded. The object that the initial fill returns does not cause this problem. It is generated when accessing relationships off that graph object (but not in the midst of a getItem call). I have tried many code changes to work around this but none have worked (including using a unique ID in the fill parameters). The fact that the apps work fine on their own tell me that I am using (at least partially) the technology correctly. Does anyone have any insight into what might be going on?

Both methods, routeMessageToService and routeMessageToClient, are

Often times after a handful of these come out I get the following error: 20:53:43,877 ERROR [LazyInitializationException] could not initialize proxy - the owning Session was closed org.hibernate.LazyInitializationException: could not initialize proxy - the owning Session was closed at org.hibernate.proxy.AbstractLazyInitializer.initialize(AbstractLazyIniti\ alizer.java:60) at org.hibernate.proxy.AbstractLazyInitializer.getImplementation(AbstractLa\ zyInitializer.java:111) at flex.data.assemblers.HibernatePropertyProxy.getHibernateProxyValue(Hiber\ natePropertyProxy.java:60) at flex.data.assemblers.HibernatePropertyProxy.getAlias(HibernatePropertyPr\ oxy.java:67) at flex.messaging.io.amf.Amf3Output.writePropertyProxy(Amf3Output.java:533) at flex.messaging.io.amf.Amf3Output.writeCustomObject(Amf3Output.java:518) at flex.messaging.io.amf.Amf3Output.writeObject(Amf3Output.java:193) at flex.messaging.io.amf.Amf3Output.writeObjectProperty(Amf3Output.java:243\ ) at flex.messaging.io.amf.Amf3Output.writePropertyProxy(Amf3Output.java:549) at flex.messaging.io.amf.Amf3Output.writeCustomObject(Amf3Output.java:518) at flex.messaging.io.amf.Amf3Output.writeObject(Amf3Output.java:193) at flex.messaging.io.amf.Amf3Output.writeObjectArray(Amf3Output.java:800) at flex.messaging.io.amf.Amf3Output.writeAMFArray(Amf3Output.java:431) at flex.messaging.io.amf.Amf3Output.writeObject(Amf3Output.java:179) at flex.messaging.io.amf.Amf3Output.writeObjectProperty(Amf3Output.java:243\ ) at flex.messaging.io.amf.Amf3Output.writePropertyProxy(Amf3Output.java:549) at flex.messaging.io.amf.Amf3Output.writeCustomObject(Amf3Output.java:518) at flex.messaging.io.amf.Amf3Output.writeObject(Amf3Output.java:193) at flex.messaging.io.amf.Amf0Output.writeObject(Amf0Output.java:181) at flex.messaging.io.tcchunk.TCCommand.getCommandResponse(TCCommand.java:42\ 0) at flex.messaging.endpoints.rtmp.AbstractRTMPServer.dispatchMessage(Abstrac\ tRTMPServer.java:1013) at flex.messaging.endpoints.rtmp.NIORTMPConnection$RTMPReader.run(NIORTMPCo\ nnection.java:435) at edu.emory.mathcs.backport.java.util.concurrent.ThreadPoolExecutor$Worker\ .runTask(ThreadPoolExecutor.java:665) at edu.emory.mathcs.backport.java.util.concurrent.ThreadPoolExecutor$Worker\ .run(ThreadPoolExecutor.java:690) at java.lang.Thread.run(Thread.java:619) I understand Hibernate lazy initialization problems but I'm not explicitly accessing a relationship that isn't loaded. Could these two errors be related with some kind of cleanup/termination situation? Any thoughts? Thanks.
