The Wicket community is (for now) oriented around IDetachable so it's easier going that way. And I don't think detaching is a bad way to work--I use it for everything. Unfortunately, there are situations it doesn't handle well with Hibernate. If you make changes to an entity that you can't commit until several (ajax or traditional) requests later, Hibernate wants them to be in the same Hibernate session. The workaround, of merging the object into a new hb session, is rickety. Yet no web framework wanted to do long sessions. So it was a stalemate until Hibernate people decided to just make their own web framework. But you don't have to bring in Seam to get conversational sessions in Wicket. You can implement them under RequestCycle, as I've already taken a stab at: http://databinder.net/wsvn/Databinder/databinder/trunk/databinder/src/main/java/net/databinder/conv/DataConversationRequestCycle.java?op=file I'm not even sure what Seam would have to add; since Hibernate naturally does conversational sessions, integrating them with a web framework like Wicket is just writing a little code specific to that framework's request cycle and page architecture. This will be labeled "experimental" in Databinder 1.1 probably, but it worked very smoothly in the example I cooked up some time ago and have let fall off the web (it will be back though; it's replacing the regular phone directory app). It's interesting stuff, anyway.
