Thanks a lot for your time, Chuck! I hope others will join our conversation...

Just temporary while you debug the problem. I got the source, did mvn install, it generated the jar file which I then copied over to my project. If I can do it anyone can. The problem isn't in wicket but in your domain object(s). I'm out of ideas. Maybe someone from the wicket team has a good suggestion.
