What does your mapping file look like, and what problem do you see? From the bug report, it sounds like you can do it, but the big portion of the work is on the object side, rather than in the db, mapping file, or in castor. We had to do something like that in our project. We used castor to load and store the objects, but we did the relationship management on the object side. When we did it right, castor would handle the loading and the storing very well.

This means you can't have a menu that contains other menus without using an association class.
