Looks like a copy and paste went awry. Line #350 in
this class is
$recs = &amp;$this-&gt;get\_children\($dt, $orderby\);
but should be
$recs = &amp;$this-&gt;get\_parents\($dt, $orderby\);
in the get_parents_values() method.
I'll fix as soon as I can get my CVS copy updated,
unless somebody does it first.
