[ZDP] BackTalk to Document The Zope Book (2.5 Edition)/Dynamic Content with DTML

A comment to the paragraph below was recently added via http://www.zope.org/Documentation/Books/ZopeBook/current/DTML.stx#3-154
Here's an example of how to iterate over the contents of a
folder. This DTML will loop over all the files in a folder and
display a link to each one. This example shows you how to
display all the "File" objects in a folder, so in order to run
this example you will need to upload some files into Zope as
explained in the previous chapter::
<li><a href="&dtml-absolute_url;"><dtml-var title_or_id></a></li>

this code doesn't work, i've uploaded some files to the folder, and copied and pasted this code to a DTML
document, but nothing come out!

Are you sure they were honest-to-god File objects and not DTML Methods or DTML Documents or something?

but it works after i've specified the folder name, the correct coding should be

I've got another finding, the post-out coding is working under DTML method, but if using DTML document, have
to do what i said, specified the folder name. :)

Please be aware that 'honest-to-god' File objects seem to be a bit of an elitist group... when trying to
iterate over folders containing pictures, I actually had to use <dtml-in expr="objectValues('Image')">.

Right. That's because File objects have a "meta_type" of File while Image objects have a meta_type of
"Image". Try objectValues(('File', 'Image')) to get both.

How about if you are trying to iterate over DTML documents - i.e.: produce a navigation list? I've tried both
<dtml-in expr="oral_microbiology.objectValues('Document')"> and
