Load as2 clip to as3 clip and check in the as2 clip it has been loaded

Hi guys,

Could somebody help me out with loading an as2 clip into an as3 container?

Basically there is no problem with the loading itself but in the as2 clip I need to check whether this clip is loaded (the behavior differs when it is a standalone clip). However I cannot find a way to do it. I tried adding some condition to the as2 clip, something like if(this == _root) (but this is true always, even when it is loaded to as3 container) or trace(this._parent) (traces undefined always, even when it is loaded).
Does somebody have some idea how to check from the loaded as2 clip that it has been loaded into an as3 clip?

Thanks a lot!
