void onSelectionUpdated(SelectionUpdatedEvent event)
This event is fired once after selection/deselection has completed. The result is one event per mouse-down event. For a drag selection there will be two events fired: one when the first record is selected and one when the range is completed.
This event is also fired when selection is updated by a direct call to one of the
select/deselect methods. Calls on the Selection object do not trigger this event.
