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(?!?).
Solutions:
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+'/')">
ul>
dtml-in expr="objectValues('Folder')">
li>a href="dtml-absolute_url;">dtml-var title_or_id>/a>br>/li>
/dtml-in>
/ul>
/dtml-with>
The resolve_url(BASE0+'/') should give you a reference to the top Zope
object (root).

Re: [Zope] DTML Method not working
Is the code you used in a DTML Method or a DTML Document?
I had it in a DTML Method. It was in the standard public interface index_html
that is a DTML method.
Is it in a DTML Method being called from a DTML Document?
No, the standard_html_header calls the method. Actually, I just copied the
code/instructions from the Zope Book (http://www.zope.org/Members/michel/ZB/).
Incidentally, once I put your dtml-with ... modification, it worked just fine.
Thanks!
This however, begs (a newbie's) question as to how to get a listing of the
current folder's contents. I.e., using a DTML Method (such as the stadard
index_html), what changes to the code that you provided would look up the
current container's (folder) objects? Wouldn't you use something like PARENT,
i.e., the parent object of the DTML method that is used to render the web page?
Or would you simply modify the I'm going to suggest to the author of the
upcoming Zope book to add a little of your explanation here, as it would be very
instructive.
You helped. Thanks very much.

You could try something like:
dtml-with expr="resolve_url(BASE0+'/')"
ul
dtml-in expr="objectValues('Folder')"
lia href="dtml-absolute_url;"dtml-var title_or_id/abr/li
/dtml-in
/ul
/dtml-with
The resolve_url(BASE0+'/') should give you a reference to the top Zope
object (root).

Subject: [Zope] DTML Method not working
I took some code that was in the (work-in-progress) O'Riley book on
Zope. In that example, then had a DTML Method used for identifying
folders and hyperlinking to them. The code is as follows:
ul
dtml-in expr="objectValues('Folder')"
lia href="dtml-absolute_url;"dtml-var title_or_id/abr/li
/dtml-in
/ul
The problem is, it doesn't work. I know the method is being invoked
because there is some other text that is indeed being inserted.
Moreover, there are sub-folders in the folder that calls the method.
Does anyone know what the problem is? Is it a permission issue. The
standard_html_header and _footer, show up just fine, along with logos
and such. The only part that isn't showing up is the stuff that was
supposed to be generated by the dtml-in block.
Any hints?
Thanks in advance.

Re: [Zope] DTML Method not working (Please disregard, I figured it out)
Is the code you used in a DTML Method or a DTML Document? I figured out (later) that it was indeed the DTML Method/Document issue on the latter part of my question. Please disregard my last mesage.
