ITEM_EDIT_END is dispatched from DataGrid
<mx:DataGrid id="dg" itemEditEnd="itemEditEndHandler(event)" />
private function itemEditEndHandler(event):void
{
if (!dataIsValid(dg.itemEditorInstance.text))
event.preventDefault();
}

going away. What most folks do is check validation on ITEM_EDIT_END
and prevent the change to the dataprovider by calling
preventDefault(). You can also catch ITEM_EDIT_BEGINNING and return
the editor to the bad cell if the user is tabbing or clicking another
cell, but if the user clicks outside you can't really restore focus to
the cell.

the grid without warning. It's only when I click on the grid to edit
it a second time, that the red halo with the 'invalid input' flag
appears. Help appreciated.
