Ohhhh!! Sorry, yes, this is fixed in the 2.3 branch and will be out with the next release. There was a place where the __len__ of the catalog object could "go negative" that was fixed. See http://lists.zope.org/pipermail/zope-checkins/2001-March/005673.html. The __nonzero__ bit was throwing me off. ----- Original Message ----- From: "Aaron Payne" <aaron@aaronpayne.com> To: "Chris McDonough" <chrism@digicool.com>; <zope@zope.org> Sent: Thursday, March 29, 2001 1:48 PM Subject: Re: [Zope] ZCatalog search problem (was: no subject)

Can this be duplicated without ZPatterns? E.g., with the Catalog in its current state can you use its methods to reproduce the same error?
Hi Chris,
Yes. Here is what I did. In the ZCatalog 1. On the Find Objects page Find objects of type: Folder (any type of obj will work) 2. On the Catalog page Select object, hit Remove The problem occurs when you select more than half of the items for removal. This is strange. If I select 1 for removal 2 are removed. Select 3, 6 are removed, etc. The error returned is a little different.
Error Type: ValueError Error Value: __len__() should return >= 0

Hi all,
I am getting an error when I query a ZCatalog. I'm working using ZPatterns with Zope 2.3.1b3 (source release, python 1.5.2, linux2), Python Version 1.5.2, System Platform freebsd4.
