JPA / OpenJPA NULL on primary key.

Question

Problem with OpenJPA. It returns null values on primary key. I debug the open jpa code and i can't find the reason why it returns null on the primary key. I start debugging and the openjpa finds the entry with all data an a value at the primary key but at some point in the code it changes the object and the primary key is gone

This is my query

for (Object o : em.createQuery("select x from AnnouncementsEntry x")
                .getResultList()) {
            //alway returns null in every row
                long id = ((AnnouncementsEntry) o).getEntryId();

This is my definition

    @Id
    @GeneratedValue(strategy=GenerationType.AUTO)
    private Long entryId;

This is my percistence.xml
