[Zope-CMF] Adapting ZClass (Compound News Item) to CMF, but s tate isn't updating in catalog

[Groot N. de]

Answering: Antonio: which tutorials did you use?
The tutorial I used were
	http://www.zope.org/Members/AlexR/CatalogAware
and
	http://www.zope.org/Members/kedai/BuildSimpleZClass

Be sure to change the name of the catalog to be used into 'portal_catalog'
otherwise the updates go to a (possible non-existing) catalog named
'Catalog'

Answering Ivo:
The suggestion to use a CMF content class as a superclass sounds fine, but
how do you retrofit a superclass in a existing ZClass with existing
instances?
