Hello,
i am using the Red hat development studio and i have a problem with the @stateless annotation.

I am following the example of the JBoss Seam tutorial (simple register application). Reading my database is no problem, so the connection is working, the only thing which is not working is my writing via entityManager.persist(object o).

As soon as I define my bean as @stateless and add the @PersistenceContext to my bean, i on the button click the following exception:
