[Zope-dev] [ZPT] Zope 3 ZPTs in Zope 2

Hi, I have a working implementation for Zope 3 ZPTs within Zope 2. It is currently implemented through a new class ZPT which implements the same functionality as Products.PageTemplates.ZopePageTemplate. I am currently thinking about the migration to the new implementation. Would it be possible to perform an in-place migration using setstate() when replacing the ZopePageTemplate implementation with the prototype code from my ZPT class? Andreas
