Hi all, I posted this 24 hours ago on the main zope list, but didn't receive a response, so I'm reposting here. I've got an ObjectManager and Folder derived ZClass that contains instances of a second rather simple ZClass. It works fine, the Manager role can access the management interface of the container, add edit and delete instances of the contained ZClass, and Anonymous can view index_html. Now, I am trying to add a permission to the container ZClass that will let a user with a specialized role that has the permission view the management interface (the 'Contents' tab) of the container and add, edit, or delete the simple ZClass instances in the container. The container doesn't have any property sheets, but the simple ZClass does. Does anyone have a simple walkthrough of what I need to do? The Zope Book only discusses adding a permission to control access to a Property Sheet. Thanks in advance, Michael Bernstein.
