[flexcoders] Getting an error when using a tree as a component

[timgerr]

Hello all, 
I was wondering if this error makes sense?  I have this tree that I made into a 
component.  When I run the script, I see the tree but when I try and click on 
one of the folders I get this error "The supplied DisplayObject must be a child 
of the caller."  Anyone know what this means????


Thanks,
