I am getting to the conclusion that the following is not supported at all.
(Using flex 3.2 SDK):
Loading one SWF into another one using 2 different loaderContext. I tried using
the Loader and the SWFLoader (and to some extend the ModuleLoader)
1- Build a simple Flex App with a combo box or Alert Message (on click of a
button for instance). (=="TestCombo.swf")
2. Load that SWF (from Step 1) using the Loader in a new application Domain (as
such:
var request:URLRequest = new URLRequest("TestCombo.swf");
_loader = new Loader();
_loader.contentLoaderInfo.addEventListener(Event.COMPLETE,handleModuleLoaded);
_loader.contentLoaderInfo.addEventListener(IOErrorEvent.IO_ERROR,handleError);
_loader.contentLoaderInfo.addEventListener(SecurityErrorEvent.SECURITY_ERROR,handleError);
_loader.contentLoaderInfo.addEventListener(Event.UNLOAD, unloadHandler1);
var context:LoaderContext = new LoaderContext();
context.applicationDomain = new ApplicationDomain(); // that's KEY!
_loader.load(request,context);
In the handleModuleLoaded function, I am simply adding the content of the
comboSWF into a vbox
vbx.rawChildren.addChild(_loader.content);
3. Attempt to see the content of the combo or click on the button to see the
Alert from the loaded SWF, and you get an exception. (see below)
TypeError: Error #1009: Cannot access a property or method of a null
object reference.

The same code works perfectly fine if you attempt to load the SWF into the same
applicationDomain, but that's totally not acceptable for us here.
Using the SWFLoader as opposed to the Loader does not even get you this far.
The TestCombo.swf is not even loaded. I get the following exception when trying
to load the module: (basically complaining about the system Manager being null)
TypeError: Error #1009: Cannot access a property or method of a null
object reference.

Anything would help. I just need to know whether that's possible or not using
flex sdk 3.2.
Cheers.
