[Zope-dev] NASTY error. Why?

[Chris Withers]

Hi,

I'm trying to do a tree walk and copy with:

<dtml-in objectValues>
 <dtml-call "REQUEST['where'][-1].manage_addFolder(id)">
 Created <dtml-var id> in <dtml-var "REQUEST['where'][-1].id"><BR>
 <dtml-if "meta_type=='Folder'">
   <dtml-call "REQUEST['where'].append(this())">
   <dtml-var iterate>
   <dtml-call "REQUEST['where'].pop()">

...etc...

but I get the following truly horrible error from the manage_addFolder

any ideas?

Chris
