        // load the owner entity

        Session session = this.sessionFactory.getCurrentSession();
        Object owner = session.get(ownerMetadata.getEntityName(), id);

        // owner does not exist anymore so no point in loading the collection

            return null;
        }/*ww w.j  a v a2  s  .c  om*/

        // get the collection by it's property name
        Object col = ownerMetadata.getPropertyValue(owner, persister.getNodeName());

        // if it is a PersistentCollection make sure it is initialized
        if (col instanceof PersistentCollection) {
