I am using JBoss 4.2.3 and Hibernate 3.2.6.
I have a method that retrieves Entities using a NamedQuery. I update a value of each entity and then run another named query (in the same method and Transaction) filtering by the old value and it returns the same Entities as if I had not changed them.
I understand that the EntityManager needs to be flushed and also that it should happen automatically but that doesn't make any difference.
I enabled hibernate SQL logging and can see that the Entities are not updated when I call flush but only when the container transaction commits.
Code:
EntityManager entityManager = getPrimaryEntityManager();
MyEntity myEntity = entityManager.find(MyEntityImpl.class, entityId);
myEntity.setStateId(State.ACTIVE);
// Flush the entity manager to pick up any changes to entity states before we run this query.
entityManager.flush();
Query countQuery = entityManager.createNamedQuery("MyEntity.getCountByState");
// we're telling the persistence provider that we want the query to do automatic flushing before this
// particular query is executed.
countQuery.setParameter("stateId", State.CHECKING);
Long count = (Long) countQuery.getSingleResult();
// Count should be zero but isn't. It doesn't see my change above
