[Zope] Passing 'document_title' to 'standard_html_header' from a method?

Hi all, I can't seem to get the 'document_title' from a method into a standard header (when using '<dtml-var document_title>' in the header file the generated page uses the title of the header file itself. Using 'title_or_id' in the header file for a method uses the title or id from the folder it is in, not the title from the method itself. Any ideas? I didn't really find a solution in the archives; it does work with DTML Documents, but not with DTML Methods? Thnx, Jonathan
