[Zope3-Users] Problem with SetIndex (from zc.catalog)

[Thierry FLORAC]

Hi,

I'm actually using a SetIndex (as defined in "zc.catalog.catalogindex"
package).
Indexing my documents works perfectly but I still have a little
problem : when trying to get to the "Advanced" page of my catalog, a
TraversalError exception is raised :

"documentCount" seems to be defined into the "SetIndex" class, so I
don't understand this error...

Thanks for any explanation,

  Thierry
