[Zope-CMF] Re: What is really "talkback" ?

[Gregoire Weber]

Hi,

in the upcoming CMF 1.5 release you can mark an attribute as ICallableOpaqueItem.
In this case the manage_after/before methods get called on copy/move, add, etc.

You should not override 'talkback'. 

 From CMF 1.5 'talkback' is only a special case implicitely called by the CMF 
machinery (but not "officially" marked as ICallabelOpaqueItem).

Have a look at CMFUid, how this ICallableOpaqueItem are used:

   http://cvs.zope.org/CMF/CMFUid/

Especialy:

   IUniqueIdAnnotation in <http://cvs.zope.org/CMF/CMFUid/interfaces.py?rev=1.12&content-type=text/vnd.viewcvs-markup>

   UniqueIdAnnotation in <http://cvs.zope.org/CMF/CMFUid/UniqueIdAnnotationTool.py?rev=1.8&content-type=text/vnd.viewcvs-markup>

File me an e-mail if questions arise.

A release candidate of CMF 1.5 will be released the next days or next week (hopefully).
