Hello: I'm trying to create classes in classes as per the Zope Developers Guide- page 11 "Classes inside Classes." - I've created a product, and create a Zclass in it (subclass of Object Manager) - then in the method of that ZClass, I create some more Zclassses - In those ZClasses I set up some Properties and Views - There is a "Contents" View in my parent ZClass, with a manage_main in it. - I add views to the First Zclass of the child classes --- Then I go and create a new folder at the top level. In that folder I create an instance of my Zclass In that instance, when I attempt to add on of the subclasses, I get a Zope error: Zope Error Zope has encountered an error while publishing this resource. Resource not found Sorry, the requested Zope resource does not exist. Check the URL and try again.
