Haven't run the code but my guess is that the idValue returns a null instead of "0". Take a look at AbstractSingleSelectChoice.convertChoiceIdToChoice(String) line 281. (Wicket 6.15.0) "if(renderer.getIdValue(choice, index).equals(id)" This would trigger a NPE if a null is returned, which would be the case with your "nullItem".
