I bet your using a DTML Document.  Try using a DTML Method.  The reason
why the tree tag renders nothing for the DTML Document is because DTML
Documents are not containers of other objects, they are objects to hold
DTML content.  DTML Methods are (and this is the suble thing) *methods*
of the Folder object that contains them.  They are not 'objects' in the
same sense of the term used for DTML Documents (I can hear Jim saying
now "*everything's* an object").  Because Folder objects *are*
containers, the #tree tag used in a Folder's DTML Method will render the
contents of that Folder.  Hadar's example is a little outdated, it is
based on 1.9, in which DTML Documents didn't exist, and all Documents
were DTML methods.
