Flex Validator -- Show Red Error Border on DataGrid Cell

Question

I can successfully add a validator on an item in my datagrid, by passing in the particular element in the dataProvider to the validator, but I can't get the red border to show up around the cell if the validation fails.

I have stepped through the validator, and confirmed that it is passing back a failure, but I can't figure out why the red error border doesn't show up. I have a feeling its because I am passing the item in my dataProvider as the validator source, rather than the 'cell' item, but I can't find a way to access the cell.

Thanks.

If you use an AdvancedDataGrid, there is a styleFunction you can specify that might suit your needs. You can put logic in the function specified to change various attributes of the cell.
