Hi, Over the years I have heard of similar ideas... and I also implemented some "factory thing" that was able to create some CRUD form out of some annotated Hibernate JPA/POJO for some private project: I remember it was Spring based too...
I think there was also some apache project exploring such ideas. Maybe other wicket developers can remember if this is correct?
