Hi!

I quite don't understand why I have to call em.refresh(entitybean) in every funtion of a stateful session bean that trys to modify bean values. Maybe someone can give me a pointer. This is my code (non-important columsn snipped)

Entity(access=AccessType.FIELD)
@Table(name="myentity")
public class MyEntity implements Serializable {

 @Id(generate = GeneratorType.AUTO)
 private Long id;

 @Column
 private Boolean seen;

 // getters and setters ommitted

 @Override
 public boolean equals(Object o) {
 if (o instanceof MyEntity) {
 MyEntity p = (MyEntity) o;
 if (p.getId().equals(this.getId()))
 return true;
 else
 return false;
 }
 return false;
 }

 @Override
 public int hashCode() {
 return this.id.hashCode();
 }

}

The stateful session bean is saving a local copy of the used MyEntity in its state:

@Stateful
@Remote
@SecurityDomain("other")
public class BusinessManagerBean implements BusinessManager, Serializable {

 @PersistenceContext(unitName="mypersistencecontext")
 EntityManager em;

 private MyEntity entity;

 // part of the remote interface
 public boolean createNew() {
 entity = new MyEntity();
 entity.setValue(true);
 em.persist(entity);

 // the following change will automatically propagated to the database
 entity.setValue(false);
 return true;
 }

 // public remote interface function
 public boolean doBusinessLogic() {
 // em.refresh(entity);
 // change not propagatec to database unless the above em.refresh() is commented out
 entity.setValue(true);
 return true;
 }
}

The entity is not detached from the database (e.g. em.remove(entity) works flawlessly). However, I have no idea why I have to em.refresh() it each time.

(I tried adding em.flush() at various places with no success).

The above is only a small testcase of mine that still shows this behaviour. In reality, the MyEntity has a HUGE datagraph within ManyToMany/OneToMany relationships, and calling em.refresh() each time takes a copule of seconds, so as you can image it's inacceptible for me to call em.refresh() in every singe business function.

Thanks for any pointers.
