Hi Francois, Okay, I see what you're saying now. Yes, that makes sense - I can just hardcode those values and not bother overriding other methods. It loses the flexibility on setting the max value in the constructor, but I don't actually need that in my situation and I agree that it is a good compromise! And eventually, the resource replacement feature after upgrading to wicket 6 will be the ideal solution. Thanks for your patience and the help!
