Is the code you used in a DTML Method or a DTML Document?

Is it in a DTML Method being called from a DTML Document?

If the answer to either of these is 'yes' then it's doing as you ask!

The thing that gets most new zope users is that a DTML Document is itself a
container.  This means that anytime you use code similar to yours or when
using a <dtml-tree ...> it will probably return a blank, as the DTML
Dopcument has no children(?!?).


1.    Try moving the code into a DTML Method.
2.    Use a dtml-with around it.

The second one works most places but if in the root then it's slightly more
difficult as the top object is hard to reference (please someone tell me I'm
wrong here).

You could try something like:

<dtml-with expr="resolve_url(BASE0+'/')">
<dtml-in expr="objectValues('Folder')">
 <li><a href="&dtml-absolute_url;"><dtml-var title_or_id></a><br></li>

The resolve_url(BASE0+'/') should give you a reference to the top Zope
object (root).

Subject: [Zope] DTML Method not working
