is it possible to do a bi-directional drag and drop. For example, dragging and dropping from left to right will remove the selected item from the database and other way will add items to the database. This is the puzzling thing, it seems as if the bean receiving the action has to implement DragListener or DropListener and overload the processDrop or processDrag. This seems to present a problem in the bi-directional case as you are locked in to one processDrag and one processDrop. Does anyone have any ideas on performing bi-directional drag drop with richfaces?
Did you tried to make something before post? for example placing both drag and drop support to both zones with specifying proper actions? Are in this case any problems appears?
