I've been looking through Zope material (e.g. the Zope Bible) and most of it talks about building products from scratch. One thing I constantly find myself doing is say "What I really want is a new class of 'Folder' objects but that display, for example, some additional information when rendered". In other words, variations on the existing content types. It appears that I can use both ZClasses and Python products to do this. My problem is that I'm working with Plone/CMF content types and they seem pretty complicated to derive new content types from. If, for example, I just wanted to create a new class of folders but override the "view" (page template?), what is the best way to do that. I'd like to be able to do much of it from the web, but it isn't clear to me how I'd override something like the "view" (document_view?) method for python-based products. Anyway, I'm not asking somebody to tell me, step by step, how to do this (although I wouldn't mind :-), just some suggestions, pointers, etc. to help me get going. Thanks. -- Mike
