Hi,
I'm re-implementing my nested ZClass product as a python product.
The ZClass product contains a class 'portal' which is the only one which should be add-able to any ordinary folder, and a cascade of further classes which can be added inside the portal.
In my classes I'm able to restrict the list of contained classes via _allowed_meta_types. But in an ordinary Folder, any object can be added.
Is it possible to prevent the further classes to show up in the normal list, so that only 'portal's can be added to a normal Folder object? Or is the only solution to throw an exception?
If you only use: from ZClasses import createZClassForBase createZClassForBase( base_class=YourProduct.HiddenBaseClass, pack=globals() , nice_name='YourHiddenBaseClass', meta_type='YourHiddenClass' ) you can derive from your class in ZClasses, but they dont show up in the add list.
