[flexcoders] How to play an animation when removing a child on a state change

[boy_trike]

I change my state to "X" and have a removeChild statement to remove a datagrid 
(since 
something else will take its place).  My question is how can I have an effect 
play instead of 
just having it disappear.   It seems like my RemoveChild statement is played 
before any 
transition is played.

Thanks
