--------------------------------------
I'm having the exact same problem using Hibernate 3.2.5.ga and MySQL 5.1. I have
disabled the query cache.
The workaround introduced by Richard Ogin does not work for me. I can confirm that
invoking createCriteria() or createAlias() on any existing Criteria object makes
Hibernate ignore everything that has been set through setFetchMode().
The following Criteria succeeds:
Criteria a = getSession().createCriteria(AlbumHierarchyNode.class);
a.setFetchMode("albums", FetchMode.JOIN).setFetchMode("albums.album",
FetchMode.JOIN).setFetchMode("albums.album.library", FetchMode.JOIN);
a.add(Restrictions.isNotNull("parent"));
a.setResultTransformer(Criteria.DISTINCT_ROOT_ENTITY);
a.list();
The following Criteria fails:
Criteria a = getSession().createCriteria(AlbumHierarchyNode.class);
a.setFetchMode("albums", FetchMode.JOIN).setFetchMode("albums.album",
FetchMode.JOIN).setFetchMode("albums.album.library", FetchMode.JOIN);
a.createCriteria("albums").createCriteria("album").add(Restrictions.in("status",
filter.getStatuses()));
a.add(Restrictions.isNotNull("parent"));
a.setResultTransformer(Criteria.DISTINCT_ROOT_ENTITY);
a.list();
setFetchMode ignored if using createCriteria

Project: Hibernate Core
Issue Type: Bug
Components: query-criteria
Affects Versions: 3.2.5
Environment: Hibernate 3.2.5, Oracle 8
Reporter: Peter Weemeeuw

Hi,
It seems that criteria.setFetchMode gets ignored if you combine it with createCriteria to
add a restriction.
This works as expected:
DetachedCriteria c = DetachedCriteria.forClass(MenuItem.class);
c.setFetchMode("menuItemSubscriptions", FetchMode.JOIN);
But in this case the join doesn't happen (and I get a LazyInstantiationException
further on).
DetachedCriteria c = DetachedCriteria.forClass(MenuItem.class);
c.setFetchMode("menuItemSubscriptions", FetchMode.JOIN);
c.createCriteria("menuItemSubscriptions").add(
Restrictions.eq("location", "B")
);
This does not happen if I set lazy="false" in the mappings
file.
Regards,
Peter
