Um, why go there?  I mean, I don't know what is bothering Zope, but there are
easier ways to get what you want::

  <!-- skip the derer altogether, use properties directly -->
  <dtml-in "objectValues()">
   <a href="&dtml-absolute_url;"> <dtml-var id> </a>
  </dtml-in>

or, if you really just want the ids::

  <dtml-in "objectIds()">
   <dtml-var sequence-item>
  </dtml-var>
