I wanted to add some error processing to some of the parameters I receive and the processing is 'generic' for any integer types.
The easiest way to do this would be in a derivative of the PageParameters class. Given that wicket has lots of plug ins facilities and customizing options I was wondering if it's possible to specify a PageParameters factory to provide objects that wicket should use when processing a request.
