[Zope-dev] Weird Re-Indexing Errors after move to Zope 2.3.1b1

[Chris Withers]

Hi, 

Since moving one of our servers from Zope 2.2.4 to 2.3.1b1, we've been
frequently getting this weird error when trying to do something that requires an
object to be re-indexed in the Catalog:

Error Type:  AttributeError
Error Value: 'tuple' object has no attribute 'append'

Traceback:
 Traceback (innermost last):

  File /usr/local/zope/cases/Products/aProduct/aProduct.py, line xxx, in

insertReverseIndexEntry
AttributeError: 'tuple' object has no attribute 'append'

Any ideas what's going on here or how to fix it?

cheers,

Chris
