First of all, thanks for your patience for reading this long post.......I posted it twice a while ago but had no replies so am trying again......

Our development site has approx the following structure:

index_html
- About
   |
   Guided Tour
   |
   Machine
- Jobs
- Beamlines
- Machine
   |
   Parameters
etc


Inside each folder is a contents_html document. The index_html is at
the root and displays this content under a generic banner with drop
down menus (Javascript) with links to the top level folders and their
subfolders.

Local navigation is generated via a treemenu which
generates absolute_urls.

However we get the following error when clicking a link in the treemenu, to http://mysite/About/GuidedTour

Error Type: KeyError
Error Value: Parameters

I presume that Zope moves up to the root to pick up the index_html then moves back down until it finds the first "Machine" folder, which is not the one we want then raises an error.

Does this mean that in Zope no two folders can have the same id? This would cause problems when our contributors edit their parts of our site. Is there a way around this other than naming the folders differently?  I remember seeing something about tpId somewhere....
