Hibernate inserts duplicates into a @OneToMany collection

Question

I have a question concerning Hibernate 3.6.7 and JPA 2.0.

Consider following entities (some getters and setters are omitted for brevity):

@Entity
pub         


        

Answer 1

By using Java enterprise context in Wildfly (8.2.0-Final) (I think it's Hibernate version 4.3.7) the workaround for me was, to first persist the child an the add it to the lazy collection:

...
@TransactionAttribute(TransactionAttributeType.REQUIRES_NEW)
public void test(){
    Child child = new Child();
    child.setParent(parent);
    childFacade.create(child);

    parent.getChildren().add(cild);

    parentFacade.edit(parent);
}
