    Session sess = openSession();
    Transaction tx = sess.beginTransaction();
    sess.persist(s);
    sess.flush();
    sess.clear();
    s = (Search) sess.createCriteria(Search.class).uniqueResult();
    assertFalse(Hibernate.isInitialized(s.getSearchResults()));
    Iterator iter = s.getSearchResults().iterator();
    assertEquals(iter.next(), "HiA");
    assertEquals(iter.next(), "hibernate.org");
    assertEquals(iter.next(), "jboss.com");
    assertFalse(iter.hasNext());
