Re: [Zope-CMF] Customising types with add views

I suspect it's YAGNI since the add view calls _setPortalTypeName() on the newly created instance as well, so the resulting object will have type Beta, not type Alpha. Oops! I just realized that I didn't read your example correctly. I thought you would *want* to set Beta's fti.factory to something different. As you noticed, using the same factory *and* add view for different portal types is supported. In fact that's the reason why we adapt the type info and can't use normal browser pages.
