Hi, I'm hoping to get some feedback to a question I've had about whether making ZClasses Catalog Aware is a good idea or not. Below is a my question I asked and a few ideas from a response I received, can anyone validate/invalidate any of these statements? kh Question: ------------------ Is it good practice to simply make ZClasses Catalog Aware by default, or is this something that should only be done when necessary? Response ---------------- - Object cutting and pasting does not work properly for CatalogAware ZClasses. Is this a problem for you? Note you can still copy, paste and then delete the original object. - CatalogAware ZClasses look slightly more "fragile". I've seen posting about (fairly elusive) errors in Catalogs with such ZClasses. Note I never experienced them firsthand. - You could first create a base ZClass, then subclass it when creating your actual ZClasses. This base ZClass could include common stuff such as CatalogAwareness. Then if you change your mind you just need to modify the base ZClass. There is a way to change the base classes for a ZClass, though it's a hack.
