em.persist should work. But there are some mistakes in your architecture. If there is a underlying JSF page that uses the "group" component, you need to make the bean a Stateful Bean. Furthermore, the PersistenceContext needs to be EXTENDED. Otherwise the entity will get detached, and that's the reason why persisting failed.
