[Zope] Re: [Zope3-Users] Cannot view the instances after I refresh the product in ZMI

[Peter Bengtsson]

You're most likely getting that error because your product is 
subclassing another product that has been refreshed.
Suppose you do this in MyAProduct.py

from Products.AnotherProduct.Foo import SomeClass
class ThisProduct(SomeClass):
   bla bla bla


If you refresh AnotherProduct, the MyAProduct will break and you'll get 
the error you mentioned.
