[jboss-user] [JBoss Seam] - isNull not working for one-to-one relation

When I try to create a criteria like the following: | Criteria c = ((SessionImpl) entityManager.getDelegate()) | .createCriteria(Person.class); | | pCriteria.add(Restrictions.isNull("location")); | where location is the attribute of an one-to-one relation, i don't get any hit in the resultlist, even there are records in the database matching this criteria.
