Can you be more specific? What kind of unexpected runtime exceptions are you talking about? I don't think I understood you correctly.
Any runtime exception thrown by the wicket is caused by a programming error... there is no sense to catch it without fixing the problem in your code. Catching runtime exception could make sense if the runtime exception is thrown by some business logic you are invoking inside wicket components.... but this kind of issue is your responsibility..
