[Zope] Refreshing products

[Thierry Florac]

  Hi,

I currently use Zope-2.5.1 and started to develop a new product.
This product have internal properties which are common strings or
integers, but also instances of internal classes which are stored in
lists and dictionnaries.

Everythink works fine, until I restart Zope or make a 'refresh' on my
product : then, these internal properties are lost !!

What should I do to be able to keep these properties ??

Thanks for any help,

  Thierry
