[flexcoders] Cannot select identical item in my tree component...

[whiskerstasters]

Hi everyone, I'm having an issue with my tree component.
I use an arrayCollection for my dataProvider. 
I have the same object in my arrayCollection nested at different levels.

I cannot select this object at different levels in my tree, it always select 
the topmost nested object.

Is there a way to work around this? I would like to be able to select an item 
even though the same item is found at different nested levels within the tree.

Thanks!
