Revision 77

have a look at the "valueIsAdjusting" parameter when updating the preview. Without this change, when the selection is inverted, there have been too many preview updates.

  featuresTable.getSelectionModel().addListSelectionListener( new ListSelectionListener() {
      public void valueChanged(ListSelectionEvent e) {
    	  if (!e.getValueIsAdjusting()) 
    		  performListSelection();
      }
    } );
