[Zope-dev] Broken instances when upgrading from 2.1.6 to 2.2

[Peter Arvidsson]

Hi

I had the same problem... I dont know what the problem was but I deleted the
imported product (ZClass) and created a new exactly equal product from scratch
(of course I saved all the code I had and used copy and paste :). This worked
for me.

Any1 know why that problem show up in 2.2 ?
