> Key: OPENJPA-1571
> URL: https://issues.apache.org/jira/browse/OPENJPA-1571
> Project: OpenJPA
> Issue Type: Bug
> Affects Versions: 2.0.0-beta2
> Reporter: Fay Wang
> Assignee: Fay Wang
> Fix For: 2.0.0
>
>
> Given an entity:
> @Entity
> public class EntityB {
> @Id
> private int id;
>
> @ElementCollection(fetch = FetchType.EAGER)
> @CollectionTable(name = "setIntegerTable", joinColumns = @JoinColumn(name
> = "parent_id"))
> @Column(name = "value")
> private Set<Integer> intVals;
> ...
> }
> The following test scenario
> EntityB b1 = em.find(EntityB.class, id);
> em.clear();
> b1.getIntVals().remove(new Integer(1));
> b1.getIntVals().add(new Integer(2));
>
> em.getTransaction().begin();
> EntityB b2 = em.merge(b1);
> em.getTransaction().commit();
> em.clear();
> EntityB b3 = em.find(EntityB.class, id);
> Set<Integer> intVals = b3.getIntVals();
> ==> this intVals still only contains Integer(1), not Integer(2).
