[Zope] DTML to ZPT Question

[Michael Murphy]

For what it is worth, I was able to devise a work-around that may better
illustrate the problem.  I renamed the "index_html" Page Template to
"index_html2", and created the following DTML Method of "index_html":

<dtml-in expr="objectValues()"></dtml-in>
<dtml-return index_html2>

Further, the original "index_html" Page Template won't fail if I remove
'Page Template' from the set of requested objectValues.  i.e.
tal:repeat="objs python:here.objectValues(['Folder','DTML Method'])"
