[Hibernate-JIRA] Commented: (HHH-1413) Multiple Bag fetches
by Sergey Koshcheyev (JIRA)
[ http://opensource.atlassian.com/projects/hibernate/browse/HHH-1413?page=c... ]
Sergey Koshcheyev commented on HHH-1413:
----------------------------------------
It seems that not only multiple bag fetches should be disallowed, but any multiple collection fetches which include a bag (with possibly some exceptions). For example, this currently fails for me on H3.2 from SVN (put this into ASTParserLoadingTest.java):
public void testBagSetFetchFails() {
Session s = openSession();
s.beginTransaction();
Human human = new Human();
human.setFriends(new ArrayList());
Human friend1 = new Human();
Human friend2 = new Human();
human.getFriends().add(friend1);
human.getFriends().add(friend2);
friend1.setNickNames(new TreeSet());
friend1.getNickNames().add("nick1");
friend1.getNickNames().add("nick2");
friend2.setNickNames(new TreeSet());
friend1.getNickNames().add("nick21");
friend1.getNickNames().add("nick22");
s.save(human);
s.save(friend1);
s.save(friend2);
s.getTransaction().commit();
s.close();
s = openSession();
human = (Human) s
.createQuery( "from Human h join fetch h.friends f join fetch f.nickNames nof" )
.uniqueResult();
assertTrue(Hibernate.isInitialized(human.getFriends()));
assertEquals(2, human.getFriends().size());
s.getTransaction().commit();
s.close();
}

> two options here:
> 1) disallow
> 2) fall back to subselect fetching (or another more appropriate fetching strategy) for all but one of the bags.

[Hibernate-JIRA] Created: (HHH-2458) Order, Example ... overriding equals method
by Joris Wijlens (JIRA)
Order, Example ... overriding equals method
-------------------------------------------
Key: HHH-2458
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2458
Project: Hibernate3
Type: New Feature
Components: query-criteria
Versions: 3.1.3
Reporter: Joris Wijlens
Priority: Minor
It would be nice if the criterion classes like Order and Example would override the equals methods. This is easier when testing dao with mock objects that use an equals matcher like easy mock does
