Hi folks,
I've been battling this problem for a while now and I'm at my wits' end.
I'm trying to implement a plugin system for our application, and having a devil
of a time getting SWF file which was dynamically loaded itself, load additional
SWF files.
It goes something like this:
1. Main Application Shell loads...
2. ---------+ Application loads...
3. -----------------+Plugin(s)
We have no problem getting app #1 to load app #2
However, try as I might, I cannot get app #2 to load and instantiate #3
I've tried various permutations using the ModuleManager, but this is the
closest I get. When the onLoadComplete method get invoked, I can see that the
SWF loaded, however the factory always returns NULL.
What is interesting is that when I extract this out in its own application, it
works fine. This issue is triggered by the fact that I'm loading Plugin from a
SWF that was loaded dynamically itself.
I believe this is due to the ApplicationDomain, but I cannot make heads or
tails of it. I tried specifying currentDomain, new
ApplicationDomain(Application.currentDomain) and new ApplicationDomain()
without success.
Also, it is important to note that I cannot make reference a hard reference to
the Foo class in either applications since by their nature, we will not know
ahead of time what they will contain.
Googlin' around, this seems to be a fairly known problem, but I have not found
a (clear) solution yet.
Any idea/help ? Thanks a bunch !

assetModule = ModuleManager.getModule("Foo.swf");
assetModule.addEventListener(ModuleEvent.READY, onLoadComplete );
assetModule.addEventListener(ModuleEvent.ERROR, onLoadError);
assetModule.load();
.
.
.
private function onLoadComplete( event:Event ):void
{
trace("module loaded");
_pluginInstance = assetModule.factory.create() as Plugin;
if( _pluginInstance )
_pluginInstance.startup();
else
Alert.show("unable to instantiate module");
}
private function onLoadError( event:Event ):void
{
Alert.show("error");
}
My Plugin looks like this:
package
{
import mx.collections.ArrayCollection;
import mx.modules.ModuleBase;
public class Plugin extends ModuleBase
public function startup():void
{
}
.
.
.
}
and
package
{
import Plugin;
import mx.collections.ArrayCollection;
import mx.controls.Alert;
import mx.modules.ModuleBase;
public class Foo extends Plugin
{
public function Foo()
{
trace("foo constructor invoked");
}
override public function startup():void
{
trace("foo started");
}
.
.
.
}
