What steps will reproduce the problem?

3. The array collection can even be empty

What is the expected output? What do you see instead?
Expected to see the new data in the component

What version of the product are you using? On what operating system?
version 2.5-flex3 on windows 7

Please provide any additional information below.
This is for the treeGrid component, seems that the index is not being reset or 
something along those lines, when a new arraycollection is assigned to the 
dataprovider.

I tried a work-around by making a deep copy of the original, which i could then 
use to "reset" the component each time i want to assign a dataprovider. I could 
not get ObjectUtil.copy to work with the component though.

Alternative would be to recreate the component each time.
