Seam-gen fails with this DB model

[phantasmo]

I have a model like this: a User can have other Users as friends. A friendship has a Data_since attribute in addition to foreign keys, like this:

Users      
id*, name  

Friendships
id1*,id2*, since

After seam-gen is used to reverse engineer this data structure, "seam explode" fails saying something like: "usersHome is already defined in test.action.FriendshipsHome".

When I change the DB structure, so that Friendships has only one foreign key referencing User's ID, it works fine.

Is there anything I can do about this?

Thanks.

Is there more than one FK defined on Friendships table referencing the same table (Users)?

If yes, why?

I would imagine that Friendships.id1 is the PK and Friendships.id2 is the FK to Users.id, correct?
