good. there are some internals that do not count on a runtime
exception being thrown because of user code...for example throwing it
out of something like validator will abort entire form processing, and
might leave that particular form component in an inconsistent state.
but throwing it out of onclick/onsubmit handlers shouldnt pose much
problem as most wicket processing has already happened.
