[jboss-user] [JBoss Seam] - Re: selectOneMenu - NPE

Ah. I posted my message before you posted the exception. Anyway: please make sue you are using the entityManager (and is named entityManager). This seems correct according to your posted XML. Your entity has to have a @Id. Make sure of that. NPE seems to be at EntityIdentifier key = new EntityIdentifier(entity, getEntityManager()); Eventually make a brackpoint here and see what is null.
