Hebert Coelho created OPENJPA-2333:
--------------------------------------

             Summary: Problem with duplicated results in criteria
                 Key: OPENJPA-2333
                 URL: https://issues.apache.org/jira/browse/OPENJPA-2333
             Project: OpenJPA
          Issue Type: Bug
    Affects Versions: 2.2.1
         Environment: linux or windows
jdk 6 or 7
OpenJPA 2.2
            Reporter: Hebert Coelho


I have described the problem in here: http://openjpa.208410.n2.nabble.com/Problem-with-JPA-Criteria-td7582759.html#a7582764

The code bellow brings duplicated results when it should only bring one result


        CriteriaBuilder criteriaBuilder = em.getCriteriaBuilder();

        CriteriaQuery<Person> criteriaQuery = criteriaBuilder.createQuery(Person.class);
        Root<Person> mainRoot = criteriaQuery.from(Person.class);
        criteriaQuery.select(mainRoot);
        mainRoot.join("dogs", JoinType.INNER);
        Predicate predicate = criteriaBuilder.and(criteriaBuilder.equal(mainRoot.get("dogs").get("name"),
"Fire"));
        criteriaQuery.where(predicate);

        TypedQuery<Person> criteriaGeneratedQuery = em.createQuery(criteriaQuery);
        System.err.println(criteriaGeneratedQuery.getResultList()); // brings two objects
instead one



In the tested database, there is only one dog named Fire.

If you need more information, just say it.
