I can’t seem to figure out why this is happening. I’m adding a bunch of movieclips to a container clip. I then add that to the scrollpane. When I run scrollpane.update() it gives me the error “The supplied index is out of bounds”. From the full error message it looks like it’s happening on the DisplayObjectContainer/getChildAt() which is run in the update() method. Any thoughts why this would be happening? I thought I had it going once but now it’s not again and I can’t figure out what I was doing differently.
