New subject: [Zope] zope product, object manager problem

14 Jun 2004

      I have a zope interface Person with a PersonImplementation that
inherits from OFS.ObjectManager.  When I try to add some product (eg a
Folder) instance to an instance of a Person, everything appears to
work, but nothing shows up in the listing of the person.

Eg if I go to

  http://my.server:8080/sandbox/jdh/manage_main

where jdh is a Person instance, I see 

  There are currently no items in jdh

I am posting my code below in hopes someone can point out my mistake.
I am trying to follow the code example from the ZDG.

Thanks,
John Hunter
