I'm not sure I understand that :) Could you please clarify? Do you mean hibernate fetched collection to Provider bean and did not refresh when User form saved (== links changed)? If yes, why usernames were refreshed - these referenced from collection and refreshed properly.

I agree that probaly I'm wrong when blame Seam but there are a lot of annotations and I assumed that some combination (or simply missed) annotations lead to this side effect.

At the moment I "brute-forced" it :) - set event listener to post-ins/upd/del event, register provider form method as event observer and check for collections inconsistencies

  |   if (r instanceof User) {
  |             User u = (User)r;
  |             if (getProvider().getUsers().contains(u) != u.getProviders().contains(getProvider())) {
  |                 entityManager.refresh(getProvider());
  |             }
  |         }
  | 
It works but I'm sure there is better solution (at least not so "in-place").
