[Zope-dev] Don't try to index URL (or any other REQUEST property)

[Jean Jordaan]

Hi all

Turns out that one major cause of my ZCatalog hassles was 
that I had an index called 'URL'. That is, my ZClass had 
a property called URL, and I was indexing on this. It makes
everything in the ZCatalog vanish. "No objects in Catalog".
Deleting this index makes everything re-appear again! :)

It seems that having indexes with names that appear in the 
REQUEST object is a definite no-no.

Regards,
Jean
