[Zope] Help with 'sequence-item'???

[mike.keller@systoc.com]

Hi,

I have searched the archives for references to this and read what I could find in two Zope 
books and the online zope book, but cannot figure out why this one does not work. If 
anyone could help point me in the right direction, I certainly would appreciate!!!! :->

Running Zope 2.43 locally on a Windows platform (W2K)
Installed the ExtFile product, can add files to folders and am using the following code to 
iterate over the contents:
<p>
<ul>
<br>
<dtml-in "objectValues('ExtFile')">
  <li>
  <dtml-var "(_['sequence-item'].icon_gif())"><br>
  <a href="&dtml-absolute_url;"><dtml-var title></a><br>
    
  <dtml-var descr>
  <br>
  </li>
</dtml-in>
</ul>
<br>
</p>
The line referencing the 'sequence-item' should be returning the icon that is associated 
with this document mime type. Instead, I get a single icon and no text or URL output when 
this is run on a folder with 2 documents in it. If I remove the 'sequence-item' line, output is 
as expected, a URL and the description of the documents. 

Again, any help with that line would be appreciated!!

Thanks,
Mike
