Hi, I've noticed that spark datagrid doesn't support ITEM_EDIT_END only Session_save and session_cancel which is different from what mx:Datagrid behavior. With ITEM_EDIT_END (which should be "ITEM_EDIT_END"), we have the possibility to validate our data outside of our itemEditor and call preventDefault() to prevent the item editor to be destroyed which doesn't seem to be possible right now with the current implementation. My question is, should the spark datagrid support this case scenario? If so I'll create a ticket and create the patches necessary to fix it.
