[Zope] Zope 2.8.0 monkey patch issue
Hi, I am trying to migrate from Zope 2.7.6 to 2.8.0 In some product I did, I need to monkey patch some OFS and CMF classes (I do this in product init). I get this error whenever I try to do someclass.__dict__[someclassattributename]=newvalue : TypeError: object does not support item assignment This was working fine in Zope 2.7.x Any idea what could have changed that would imply this ?
