To be honest, I've always found that alot of hassle just to attach a movieclip.
I've never bought into the createClassObject/createObject-way used by the v2
component framework either.
If all you're after is the correct type when using attachMovie, do the
following.
private var customClip:CustomClip
private function onLoad() {
var mc:CustomClip = CustomClip(this.attachMovie("CustomClip", "customClip",
this.getNextHighestDepth()));
// calling non-existing method - throws error
mc.someMethod();
}
Doesn't get any easier than that if you ask me.
Of course, in AS3 attachMovie is gone and we can just use:
var mc:CustomClip = new CustomClip();
;-)

Muzak
