[Zope] Two tree tags in a DTML Method/Document?

[Tony McDonald]

Am I doing something wrong, or can I only have one tree tag in a DTML 
method/Document?
(excuse the gormless example, it was the quickest one I could find...)

<!--#tree id=alpha1 branches_expr="objectValues('Folder')"-->
   <A HREF="<!--#var tree-item-url-->">       
     <!--#var title_or_id-->
   </A>
<!--#/tree-->

<hr>
<!--#tree id=alpha2 branches_expr="objectValues('Folder')"-->
   Tree#2:<A HREF="<!--#var tree-item-url-->">       
     <!--#var title_or_id-->
   </A>
<!--#/tree-->
