Hi Maarten

This nagged me, so I delved into it a bit more. It did not work as a result
of mixing DTML Methods with proper objects. The id of the DTML Method is not
a string (apparently), but of other objects it is. Or something like that (I
don't really understand this)
The resulting code is a bit more complicated than I'd have hoped for (well,
it's not _that_ bad), but it works. If someone knows something cleaner -
please tell us


  <ul>
   <dtml-if expr="_.len(PARENTS[0].objectItems())==0">
     Nothing in folder.
   <dtml-else>
    <dtml-with "PARENTS[0]">
     <dtml-in objectValues sort=id>
       <dtml-if "meta_type=='DTML Method'">
        <dtml-if expr="id() <> 'index_html'">
          <li><a href="<dtml-var absolute_url>"><dtml-var id></a></li>
        </dtml-if>
       <dtml-else>
        <dtml-if expr="id<>'index_html'">
          <li><a href="<dtml-var absolute_url>"><dtml-var id></a></li>
        </dtml-if>
      </dtml-if>
     </dtml-in>
    </dtml-with>
   </dtml-if>
  </ul>
