Jeremy,
Thanks a lot. This was the problem. But then I have a question about
design I made:
I am using wizard a lot and I found that having a "bean" that collects al
the entitties through the steps makes my code cleaner. For instance, I can
hide some model manipulation into it. But I rose this situation, where I had
to implement IDetachable in my bean.
What do you think about?
