[Zope] Arrggh, more namespace confusion ...

[Sam Gendler]

How about 
<dtml-in "objectValues(['Folder'])">
  <dtml-if "id=='folder1' or id=='folder2'">
    <dtml-var title_or_id>
  </dtml-if>
</dtml-in>


objectValues returns a list of objects of the specified type.  I believe
there is an objectIds() function that just returns id's, if that is
really all you are interested in.  If you want a listing of all folders,
you can get rid of the <dtml-if> statement.  If you want all objects,
you can just pass no parameters to the objectValues function.  

This is untested code.  I have no idea if logical or works in a dtml-if
statement (I don't know why it wouldn't).  See the ZQR for more details
on objectValues (http://www.zope.org/Members/ZQR if memory serves
correctly).
