Hi again I have a brand new problem: I´ve created a new Zclass "NewsClass" that sublasses - ZObject - CatalogAwareBase (?) - ZFolder (?) - ZCatalogBase (?) - ZObjectManager where (?) means: I don´t know why I did this. Inside NewsClass I defined an other ZClass "SectionClass" which subclasses - ZObject - ZObjectManager - ZFolder (?) I will then define another class called "ArticleClass" that will probably have - ZObject - CatalogAwareBase 1) The problem is that when I´m on a NewsClass instance, I can´t get the select menu shows me the option "Add Sections". It does shows it if I move the factory to the same level of NewsClass but, of course, this makes "Sections" (almost) available from anywhere. 2) Having a newspaper as the obvious target, am I choosing the right base classes for it? Any ideas???
