[Zope] Can't get dtml-in to work!

[Sven Fischer]

---
this must be a very dumb question, but I can't find the mistake. Anyone
seeing why
the the following DTML does not work? It does not print anything besides
'Hello',
though I created several folders in the one where the document below
resides.
Choosing different meta types doesn't help either...
---

<dtml-in expr="objectValues(['Folder'])">
   Out there !
   <dtml-var sequence-length>
   <dtml-var getId>
</dtml-in>

should be more like

<dtml-in expr="objectValues(['Folder'])">

notice the extra "[]" around it

and you don't have to play with parent afaik (cf laurie) to get it to work.
