[flexcomponents] Advanced DataGrid Issue Help???

[vin.flex]

Hi,

      I have noticed a issue. In an advanced datagrid if you open a 
row which is the last row visible then the children are not visible.
we need to scroll down to see them. is there any work around so that 
if we click to open a node, it is moves to the top so that their 
children are visible.

thanks
