[Zope] python products and properties

[Oliver Bleutgen]

Hi, 


is there a way to handle properties
in python products in order to get
similar funtionality in as propertysheets in
python?

I'm developing a product right now and it may
be that I have to add some properties later
(while in production).
Right now I have to manually assign a newly added
property to already existing instances, because
adding the property in the _properties class
attribute breaks the properties management tab of
these instances.
Am I missing something? What do others do?



Oh yeah, and I even have a great proof that I tried
to find an answer in the archieves, check out
this nice page:

It totally sold me on python products, I really didn't
know that they are *that* potent.


cheers,
oliver
