I still think I'd override the parameters getter in Application.
Class MyApp extends Application
{
Override public function get paramters():Object
{
Return systemManager.parent.loaderInfo.parameters.
}
}

Subject: [flexcoders] Re: Two questions: Nested applications styles
colllisions, flashvars injection
The _firstTime var declaration was dropped out of the code.
it's:
private static var _firstTime:Boolean = true;
Actually, the reason I used the first time is quite weird, if I set
the dispatchEventHook to null after getting the first preinitialize
event, it keeps calling it...
However, if I set it to ther fucntion it will call the other function.
Thanks,
