I'm just now using my first spark datagrid after rolling my own solution in 
Flex 4.  I've got a column of the grid using a custom item renderer which 
displays the status of a particular data item - valid or invalid - by showing 
an appropriate icon.  Im doing this by manipulating the states of the custom 
renderer and this works fine BUT after the data is loaded and I mouse over the 
any of the grid's rows, my custom renderer loses it's state. Looks like any 
rollover on the grid causes the individual cells to re-draw themselves.  

I need to override this behavior.  I want my item renderer to maintain state 
until the underlying data changes. 

Any help/suggestions appreciated.
