There's something important I forgot to mention: You might think that a group gets newly created here: @In(create=true) @Out @Valid | private Group group;
But that's wrong, it already exists: org.hibernate.PersistentObjectException: DETACHED (!!!!!!!!!!!!!!) entity passed to persist: group is definitely a MANAGED object, that was read via em.find or em.createQuery()... and then got DETACHED during Seam bijection. The only entites that are able to be persisted are those of state NEW/TRANSIENT or REMOVED. That's why em.persist() didn't work. Then you tried em.merge(), which led to an update of an existing group instead of creating a new one. And the second thing: I didn't exactly understand what's behind your register bean (I'd be interested in the JSF file). Only then we can say if the bean should be stateless or stateful ;).
