                        super.mouseUpHandler(event);
                                lastItemDown = null;
                        }
                }

=====> lastItemDown variable was private inside 
AdvancedDataGridBaseEx.as. There is no way I could override 
mouseUpHandler function to remove the code sectio that dispatches 
AdvancedDataGridEvent.ITEM_EDIT_BEGINNING event.
