Perhaps you can take a look at my implementation of the DiscussionFolder:

<dtml-tree branches_expr="objectValues(['Discussion'])">
                  <dtml-if tree-item-expanded>
                  <b>
                  </dtml-if>
                  <a href="<dtml-var "absolute_url()">">
                  <dtml-var Get_ZClass_Image> </a>
                  <dtml-var name>
                  <dtml-if tree-item-expanded>
                  </b>
                  </dtml-if>
                  </dtml-tree>

There is no expand/collapse involved here, but the nodes are 
displayed alright at:

BTW: Any comments on the Threaded Discussion task ?
