I meant that I can setup custom ART impl in mine application (WebApplication#newART()). So there is no need of instanceof, just cast and call the new method. I'm sure that no one will actually do this, because it is part of the internals and its maintenance cost will be too high. > > Before we start painting the bike shed, it's unfortunate that we don't > have Java 8 to do this properly. Wicket 8? I guess you talk about SAMs ? I'm not sure that this will help because you receive a live instance of ART in onXYZ() and it is too late to extend it at that time. You can use Scala instead. An implicit conversion could help. > > Martijn -- Martin Grigorov jWeekend Training, Consulting, Development http://jWeekend.com
