@OneToOne with CascadeType.ALL not getting deleted?

Question

I want to delete any attached child objects when removing a parent from DB. But it does not work:

@Entity
public class ParentEntity {
    @Id
    private Long id;    

    //must remain unidirectional
    @OneToOne(cascade = CascadeType.ALL, orphanRemoval = true)
    private MyEntity my;

}

@Entity
public class MyEntity {
    private String text;
}

public interface ParentEntityRepository extends CrudRepository<ParentEntity, Long> {}

When I execute:

@Autowired
private ParentEntityRepository  dao;

@Transactional
public void removeId(long id) {
      dao.delete(id);
}

Result: MyEntity row still exists in DB! Why?

I'm using hibernate, that's why I tagged the question with `hibernate`. — membersound, Aug 19 '15 at 08:51
Have you tried to move the Relation to `MyEntity` and thus making ParentEntity the "owning side"? — flo, Aug 19 '15 at 09:28

You can try this

@OneToOne(cascade = CascadeType.DELETE_ORPHAN)
private MyEntity my;

If it doesn't works you can try this:

Hibernate deleting orphans when updating collection

If you look at my example that's 100% what I have and which does not work! – membersound Aug 19 '15 at 08:33
I'm not updating a collection, but a @OneToOne object reference. Please read the question first. – membersound Aug 19 '15 at 08:41
