hey there. A small problem here.

i write:

**object.id = 1;**  
\*\*  
trace(object.id);\*\* //everything works fine  
but  
**trace(getChildAt(1).id);** //error (btw the object is for sure in position 1)  
if i try  
**trace(DisplayObjectContainer(getChildAt(1)).id);** //still error “Access of possibly undefined property through a reference with static type flash.display:DisplayObjectContainer”

Any ideas? thanks in advance
