I have the same symptoms, objects dont display in a folder subclass, but are there. Heres how I fixed it: Your base class must be the last in the class inheritance list. You must add all other base classes first. This will almost always be a problem because most base classes start with ZClass... and will be last alphabetically. (this will be much easier to fix if/when you can change, or at least reorder, the base classes of an object) eg: ZObject, ZObjectManager, CatalogAwareBase, MyBaseClass If you have a complicated object, I think you can export it in XML, reorder the base classes, & reimport. But adding/removing classes this way doesn't update the management interface tabs.
