              Looks like an application bug.

              Another exception on Component Showcase. This only happened once or twice. Not sure if it can be reproduced or not. Seems like a null check would suffice. Is it possible or common for the oldPageingValue to be null?

              public void dataModelChangeListener(ValueChangeEvent event){
              String oldPagingValue = (String)event.getOldValue();

              if (oldPagingValue.equals(PAGINATOR_SCROLLING) &&
              dataPaginatorBinding != null)

              { dataPaginatorBinding.gotoFirstPage(); }

              }
