This is not a bug. You are working whith class variable which name is
contained in $grp_index and $name_index, which both are empty - this means
you are working with $pl-><NULL> variable. If you want to get to
$this->name_index, write $this->name_index, without extra dollar. Please
read http://www.zend.com/manual/ or http://www.php.net/manual/ for syntax
about calling class variables. Also, please close this bug since it is not
a bug (at least, not a bug in PHP).
