Hi Christian!

I'd like to change the queryMethodID method of FactoryTypeInformation in
CMF 1.5 and HEAD. I want to reimplement Archetype's template mixin
feature for CMF. (*)
For the new feature I need the caller context in queryMethodID for a
dynamic view template. I propose to alter the method from
queryMethodID(self, alias, default=None) to queryMethodID(self, alias,
default=None, context=None) and add context=self to all calls of
queryMethodID.
I'm not sure I understand what you propose:
- Just changing queryMethodID signature and calls?
- Or also adding the TemplateMixin stuff to CMFCore?
- Or also adding an UI for that to CMFDefault?

TemplateMixin allows to register different view templates per portal
type. The owner of a content object can select a template that should be
used as the default template for his object. For example he can choose
that a folder should be viewed as photo album instead of folder listing
by default.
Zope 2.8/Five has a different machinery that allows to do something
similar: Adding marker interfaces to objects and specifying views for them.
This product implements the feature for Plone:
http://codespeak.net/svn/z3/Flon/trunk/
Is there a need to have TemplateMixin *and* marker interfaces? What are
the pros and cons of the two approaches?
I would be happy to contribute it to CMF 1.5 under ZPL 2.1. Is CMF 1.5
still open for new features?
CMF 1.5 is open for small features that are 100% backwards compatible.
Cheers,
Yuppie
