Subject: [Zope] IndexError


I am having IndexError in some of my folders when i tried to view the 
content of Zcatalog created in these folders, but to my surprise this is not 
happening in other folders with similar Zcatalog. I am also not experiencing 
the same problem with objects of the old Zcatalog that I have catalog before 
this error. In an attempt to correct this error, i had duplicated the old 
Zcatalog and renamed it. But once i catalog the objects and try to view it, 
it will show the IndexError again.

Traceback (innermost last):
  a.. Module ZPublisher.Publish, line 119, in publish
  b.. Module ZPublisher.mapply, line 88, in mapply
  c.. Module ZPublisher.Publish, line 42, in call_object

IndexError: 1

This error occurs when the ZCatalog is trying to build a result set during a 
catalog search and an item in the catalog index cannot be added to the 
result set.  You may have a 'broken' object which was included in the 
catalog/index when you built (reindexed) the catalog (which may explain why 
your working/renamed catalog also failed).

Try looking at the objects you are adding to the catalog and see if any of 
them are invalid.  If you have a lot of items in the catalog you may have to 
write a python script to add the objects to the catalog, one-at-a-time, and 
test after the catalog after each object has been added in order to 
determine which object is causing the problem.
