Hi, I'm using Zope 2.2.2 and for some personal reasons I need to patch the publish function from Publish.py. I used the usual __init__.py straegy to patch ZPublisher : from MyModule import Mypublish import ZPublisher.Publish from ImageFile import ImageFile # Patch the original publish function ZPublisher.Publish.publish = Mypublish But the fact is, publish is called several times at several places in the source code, and especially from the publish_module function when an exception is raised... And, although my patch works most of the times, it doesn't work when an exception is raised. I may need to replace another 'publish' reference somewhere, but does anyone know WHERE exactly ??
