For example in the EJB world if a Stateless Session Bean makes a persistence context actively associated with the active transaction and then call out to a Stateful Session Bean, the Stateful Session Bean will try and make it's persistence context the active persistence context. Now because there already is persistence context, a clash occurs and hence some problems. My question is if persistence contextx are propagated in Seam between Seam managed EntityManagers can similar problems manifest?
