[Zope] all DTML Methods of current folder and subfolder

[Wolfgang Klinger]

Hi!

I have a dtml method in a folder which should
display all "document_title"s of all 
"DTML Method"s in the current folder and
all sub folders!

(should work as navigation frame)

How can I do that?

I tried 
<dtml-in "Info.objectValues(['DTML Method'])">
where "Info" is the current folder where the
method itself is stored
but that didn't work ... :-(

any suggestions?

tia
