If it's trivial, I couldn't tell. What won't work is adding more than
one tree, which you do by iterating the objectValues. Perhaps you could
assign the objectValues parents to a list (in the same way you now try
to tree them) and take that as an input for your tree?
Like so (UNtested):

<dtml-call "REQUEST.set('plist', [])">
<dtml-in "objectValues()" size=10 skip_unauthorized reverse>
 <dtml-let a=sequence-item>
  <dtml-call "plist.append(a.PARENTS[1])">
 </dtml-let>
</dtml-in>
<dtml-tree plist>
  etc.




BTW, are you acquainted with Anthony Baxter's How-To: Some Neat Tricks
with dtml-tree. It might give you some ideas. URL:
