Code shows this is commented out:

            foreach ($pks as $pk)
            {
                /* TODO: The $item variable does not seem to be used at all
                $query = clone($this->getStateQuery());
                $query->where('a.id = ' . (int) $pk);

                $this->db->setQuery($query);
                $item = $this->db->loadObject();
                */

                // Translate the state.
                $state = null;

                if ($item->parent_id != 1)
etc.

If I uncomment this I get another notice:
Undefined property: stdClass::$parent_id
