[Zope-CMF] Changes to content.talkback in CMFCore may break compatibility in old CMF products (not CMF!)

[Gregoire Weber]

Hi Aloys,

sorry the late answer, things go always slower as one may expect ...

>content.talkback = Forum('talkback','Discussion')

Yes you would be hit by a such change. I'll think about that and 
will inform you on the steps to perform.

It's not yet decided if the change mentioned will happen before CMF 1.5.

Did you distribute you discussion forum or is your product in use in 
your sites only?

P.S.: After having done the change mentioned your manage_after*/before*
      wouldn't be called anymore if your 'Forum' class does not implement
      'ICallableOpaqueItemWithHooks' from Products.CMFCore.interfaces.IOpaqueItems.

      Caution! If you add an __implements__ = (ICallable...) to your 'Forum' class
      using the current CMF HEAD your manage_after*/before* will be called twice!

      So don't change anything for now, your compatible for now!
