I just tried this on my Zope and, unless I did something wrong, it did not
work. It failed with:

  Error Type: TypeError
  Error Value: hasattr, argument 2: expected string, int found

What has always worked for me is:

  <dtml-in "foldername.objectValues()">
    <dtml-var id>
  <dtml-else>
    Nothing in folder.
  </dtml-in>

If you want only the folders contained in foldername:

  <dtml-in "foldername.objectValues(['Folder'])">
  ...
  </dtml-in>

If you want folders and DTML Methods:

  <dtml-in "foldername.objectValues(['Folder', 'DTML Method'])">
  ...
  </dtml-in>

And so on.
