Hi i just made a form component updating behavior that works on those component (at least i think so didn't test them all)
So you just can do: RadioChoic rc = new RadioChoice(); rc.add(new XxxFormcomponentUpdatingBehavior()) I could add this behavior to the core (right besides FormComponentUpdatingBehavior) or i could integrate it into form component updating behavior (so that it knows it has to generate a little bit different code when binded to radio/check group components) or i could ofcourse do nothing.. johan
