Handling exceptions

[Federico Fanton-4]

Hi everyone!
I was wondering if there's a "best practice" for handling exceptions in a Wicket application.. I'm implementing an IDataProvider for a DataView, and I see that this interface doesn't throw any exception, so I'd guess that if something happens inside - say - iterator() that throws an exception, it should be wrapped inside a RuntimeWicketException... Am I right?
I tried the wiki, Google and "Pro Wicket" but couldn't find an answer.. ^^;;
Many thanks in advance

For maximum flexibility, provide a custom request cycle and override
onRuntimeException. Wicket 1.3 only though. For Wicket 1.2 you either
have to do with setting an error page that is useful for you, or
provide a custom request processor implementation (which is quite an
ugly thing to do in 1.2, but possible).
