 Status: Pending => Resolved

I fixed the problem with calling refreshCatalog() from a ZEO client script caused by the unavailability of self.REQUEST. But I did not accept your patch which did not solve the problem in a sane way.

>From a ZEO Client it crashes becouse the sentence "obj = self.resolve_url(p, self.REQUEST)" produces an AttributeError (REQUEST is not an attribute of self without Zope).   

What I don't know is why, in some cases, after the sentence "obj = self.resolve_path(url)" the instruction "if not obj" differs from "if obj is None".  Perhaps some behaviour of Booleans, I don't know.

In ZCatalog/ZCatalog.py there are some sentences "if not obj" that are not working fine.  I've found some cases where this sentence is true when "obj" is not None.  I think this will not affect people reindexing from ZMI, becouse of the following "obj = self.resolve_url(p, self.REQUEST)" sentence,  but it crash when trying to refreshCatalog from a simple python ZEO client.   Replacing all "if not obj" for "if obj is None" solve all the problems.   I attach a patch to do it.
