Sounds a bit similar to Apache Isis' support for domain events (albeit at a higher level of abstraction).
we've found that feature very useful, so I would imagine there would be benefits from implementing this lower more general support in Wicket. You could also perhaps submit events for the validation (allowing subscribers to veto changes).
