[Zope-dev] creating a ZClass that won't show up in normal folder add list.

I'm trying to create a couple of objects - one's a container, the other an object that only makes sense inside one of the containers. How can I get it so that the sub-object isn't listed in the normal management interface 'add' list? I've tried: - not putting an entry in the 'add list entry' field of the factory -> end up with a blank entry in the menu - not what's intended. - not making a factory object -> can't create the subobjects, get an AttributeError for _setObject. anyone? On a related note, should I be able to make a single product, with multiple ZClasses and ZFactories inside it? Anything that will break? Anthony
