Hi
I'm a newbie to wicket and i'm using RadioGroup in my application. But
sometimes it gives the following runtime exception
ERROR (RequestCycle.java:1043) - submitted http post value [radio0] for
RadioGroup component [27:paperForm:panel:radioGroup] is illegal because it
does not contain relative path to a Radio componnet. Due to this the
RadioGroup component cannot resolve the selected Radio component pointed to
by the illegal value. A possible reason is that componment hierarchy changed
between rendering and form submission.
