[flexcoders] Re: ModuleManger - READY event does not always fire
Thanks Alex. I think what I was doing wrong was that my "Modules only" Flex project had the "Framework linkage" set to RSL. This seemed to cause some of the Modules to unload (according to the debug trace output) when several Modules were loaded simultaneously. My Modules are loaded by a Flex app that loads the framework via RSLs, so the Modules are guaranteed to have all the framework classes available. The Modules don't need to load any RSLs themselves. On my Modules project, I changed the Framework linkage back to "Merged into code", however I manually modified the Link Type of the framework.swc to be "External". If I use charting, I would have to make the same change to the datavisualization.swc. This is confusing because the Framework linkage says "Merged" even though this is not true. It seems that a 3rd option should be added to Framework linkage called "External". I probably create a lot more Module projects than full-blown Application projects. On a Modules project, if I could set the Framework linkage to "External" and have it change all the Link Types like it does for RSLs, that would be a nice convenience and eliminate confusion.
[flexcoders] Re: Module unloads but FlexModuleFactory instance does not unload
After researching Application Domains, I understand now that this is not a bug. The following post by Roger Gonzalez really helped to explain what I was doing wrong: http://blogs.adobe.com/rgonzalez/2006/06/applicationdomain.html Using the following code is NOT recommended: Info.load( ApplicationDomain.currentDomain ); This places the Module's "factory" class definition in the SAME app domain as Flex. You cannot remove it once its loaded unless you shut down your main Flex application. The reason I was confused is because I misunderstood the difference between the above code and this code: Info.load( new ApplicationDomain( ApplicationDomain.currentDomain ) ); which is eqivalent to (see mx.modules.ModuleManager line 459): Info.load(); By creating a "new" app domain, the "factory" class definition is now separated from the main Flex app domain. This new domain is a "child" underneath the Flex app domain. When the Module (TestModule) is unloaded, I believe it causes the "child" app domain to go out of scope allowing it to also be GC'd. Gaurav: Thanks for testing this and helping me. I really appreciate it.
[flexcoders] Re: Module unloads but FlexModuleFactory instance does not unload
Listed below is a simple Module loading example that demonstrates the problem (source code at bottom). Create a new Flex project and set FlexApp.mxml as the "Main application file" and add TestModule.mxml as a Module. To verify that the _TestModule_mx_core_FlexModuleFactory "factory" instance is NOT getting unloaded, perform these steps: 1) Launch profiler and wait for FlexApp to load 2) Before clicking "Load Module", take a Memory Snapshot. 3) Click "Load Module" and wait for TestModule to load (its a green square). 4) Click "Unload Module" and TestModule unloads. 5) Take a 2nd Memory Snapshot. 6) Select both Memory Snapshots and click "Find Loitering Objects". You should see _TestModule_mx_core_FlexModuleFactory in the Loitering Objects list. You can double-click _TestModule_mx_core_FlexModuleFactory to obtain further details. I want to confirm that someone else can reproduce this issue before I submit a bug to Adobe. I also want to confirm that this behavior is not by design. Does anyone have any suggestions as to why this happens and possible work arounds? Note: I am using Flex Builder 3.0 (release). Thanks!

[flexcoders] Module unloads but FlexModuleFactory instance does not unload
I have a simple Module (TestModule) that I can load and unload using ModuleManager in a Flex Application (FlexApp). Profiler shows the following two new Live Objects when TestModule loads: TestModule _TestModule_mx_core_FlexModuleFactory Each object has a total of 1 instance. When I unload TestModule and force a GC, the TestModule instance and memory drop to 0 which is good. However, _TestModule_mx_core_FlexModuleFactory continues to have 1 instance and is using memory. When I grab "before and after" Memory Snapshots in Profiler, the Factory instance appears in the Loitering Objects list. The Object References for the Factory show 2 instances: -- Instance Property -- _TestModule_mx_core_FlexModuleFactory (2) Function (2)[savedThis] _TestModule_mx_core_FlexMod... moduleCompleteHandler flash.display:LoaderInfo[listner0] Function (1)[savedThis] _TestModule_mx_core_FlexMod... docFrameHandler Instance #2 is coming from the Module loading process and appears to be unloading properly. Instance #1 appears to be coming from mx.core:FlexModuleFactory. However, this code is part of the "generated" ActionScript that I cannot debug. I tried loading TestModule into the "current" App Domain and I also tried loading it into a separate "child" App Domain, however the results were the same. I'm using Flex Builder 3.0 (release). FlexApp is loading the framework.swc as an RSL. TestModule.mxml --- http://www.adobe.com/2006/mxml"; layout="absolute" width="200" height="100"> Questions: How do I unload this Factory instance? Why are there 2 instances under Loitering Objects when the Cumulative Instance count is only 1? Thanks for your help. I am really stuck on this.
[flexcoders] RSL with crossdomain.xml (Flex 2.0)
I wanted to know if it is possible to load a Flex application from one domain and have it load an RSL from a different domain assuming a properly configured crossdomain.xml file. I thought this was supported in Flex 1.5, however the Flex 2.0 docs say: "RSLs are not shared across domains. If a client runs an application in domain1 and uses an RSL, and then launches an application in domain2 that uses the same RSL, the client downloads the RSL twice." I wanted to ask before spending a lot of time trying to get this to work.

[flexcoders] Re: Loading classes
The Flex server is not compiling your Class file because FlexBuilder
is not copying it to the Flex server. Only "squares.mxml" is
getting compliled and since there is no "DrawIcons" Class present,
it "could not be loaded".
Add the following code to the top of your Script block
in "squares.mxml":
import DrawIcons.as;
This triggers FlexBuilder to copy your Class file to the Flex server
whenever it changes.
Once the Flex server has a copy of DrawIcons.as, it will compile it
and show you your errors. For example, Flex is "case-sensitive",
and your variable names are not, so Flex will complain about that.

[flexcoders] Re: Flex App with RSL fails in Standalone Flash Player
Matt: Thanks so much for the information. I was able to get the app to run in the standalone version using "File-Open" and referencing localhost. I couldn't get it to work using a crossdomain file. However, your post got me to think hard about what I was actually doing. Obviously there is a big difference between the "local file system" and "localhost". My example was trying to mix the two which is not a good idea even if it does work. (If I'm already running the main App from the local file system, then why hassle with loading an RSL from localhost?) The solution is to either run both from the local file system or run both from localhost. I had been struggling to understand the "url" attribute in the SWS definition which is why my app was a bit convoluted initially. My solution turned out to be the following simple change to myRSL.sws: Thanks again for your help. I can't tell you how many times I've searched FlexCoders and found answers to my problems from your posts and the posts of the other experts. --- In flexcoders@yahoogroups.com, "Matt Chotin" <[EMAIL PROTECTED]> wrote: > You might need a crossdomain.xml file available since the standalone is > not considered to be running from the same location as localhost in all > likelihood. > > > > What happens if you open up the standalone player, then use File - > Open > and hit http://localhost/pathtofile?

[flexcoders] Flex App with RSL fails in Standalone Flash Player
I cannot get a simple Flex application to run in the standalone Flash Player when an RSL is used. This App (with RSL) runs SUCCESSFULLY when I load it in a browser from my "localhost" web server. Its only FAILING in the SA Flash Player. If I compile the App without the RSL, it runs correctly in the SA Flash Player. I am compiling the App and RSL using the Flex command-line compilers. I am not using the runtime Flex server. Here's what happens when I run the App in the SA Flash Player: 1) The Library preloader displays "Library 1 of 1". 2) The Application preloader displays "Initializing". Progress bar goes to 100% but preloader does not disappear. 3) A very small black square with a green border appears in the upper left corner of the Flash Player. 4) If I click the small black square, the border color changes to pink. The cursor changes to a hand symbol. --- myApp.mxml --- http://www.macromedia.com/2003/mxml"; width="100%" height="100%" rsl="myRSL.sws"> --- myRSL.sws --- http://localhost/myApp/myRSL.swf";> http://www.macromedia.com/2003/mxml"; /> All the files are located in the same folder. Again: This App runs successfully in the browser! Any comments or advice will be most appreciated. Roger G.: PLEASE HELP! Thanks Yahoo!
