You only create a clone of the object, which has no context any more. Put it into a container so it gets the context for ``getParents``.

Besides this, I use the following code to clone an object:


        unsecure_source = zope.security.proxy.getObject(source_obj)
        copier = zope.copypastemove.interfaces.IObjectCopier(unsecure_source)
        new_name = copier.copyTo(new_parent)

Where ``new_parent`` is a zope.container. Removing the security proxy might not be necessary.
