Ahh… I’ve been trying at this for a while and nothing works… Okay… SO… I’m trying to make a preloader (the kind that brings in an external swf and add it as a child) for my Papervision app. But I just don’t know what I’m doing wrong. The output looks like thus:

DisplayObject3D: null  
DisplayObject3D: null  
TypeError: Error #1009: Cannot access a property or method of a null object reference.  
at PV3D$iinit()

(don’t worry about the DisplayObject3d: null, I put it in there to show that the swf is actually initializing, it’s just that at some point, it can’t go any further).

Could it be that it’s trying to access properties that are null? How do I fix that? There was another post, but it didn’t have much of a conclusion:
