Property level Long problem

[Janos Haber]

Hi!

I have a little Entity.

@Entity
@Table(name = "users")
public class User {

    @Id
    @GeneratedValue
    private Long id;

    private String name;
    private String password;
....
Setters and getters
....

If I use long primitive type, it's work, because if I use Long object
I get EntityException (I use merge NOT persist).

<openjpa-1.0.1-r420667:592145 nonfatal store error>
org.apache.openjpa.persistence.EntityExistsException: Attempt to
persist detached object .....
 ....
 hu.javaportal.web.data.dao.UserDAO.merge(UserDAO.java:22)
...

UserDAO line 22: return em.merge(obj);

Any idea?
