[CMF 2.1] Opaque items

Hi there,

I am currently migrating our CMS from CMF 1.X to CMF 2.1.

The following error is raised because the original content classes
are not derived from CMFCatalogAware.

# Module Products.HaufeCMS.DataLevel.Folder, line 170, in addDocument
# Module Products.BTreeFolder2.BTreeFolder2, line 428, in _setObject
# Module zope.event, line 23, in notify
# Module zope.component.event, line 26, in dispatch
# Module zope.component._api, line 130, in subscribers
# Module zope.component.registry, line 290, in subscribers
# Module zope.interface.adapter, line 535, in subscribers
# Module zope.component.event, line 33, in objectEventNotify
# Module zope.component._api, line 130, in subscribers
# Module zope.component.registry, line 290, in subscribers
# Module zope.interface.adapter, line 535, in subscribers
# Module Products.CMFCore.CMFCatalogAware, line 280, in dispatchToOpaqueItems
# Module Products.HaufeCMS.DataLevel.Component.Component, line 829, in
__getattr__
# Module Products.HaufeCMS.DataLevel.MetaData, line 116, in __getattr__

Is it now a requirement in CMF 2.x to derive from CMFCatalogAware or would it be sufficient to implement the opaqueXXX() methods on our own?

From http://dev.plone.org/old/plone/browser/plone.app.discussion/trunk/plone/app/discussion/comment.py#L83
and following lines it would appear you can do the latter.

Thanks - adding the related hooks returning () solves the problem. The
strange thing
in my case is that CMFCatalogAware tried to call opaqueValues() for an
instance of
a class derived from CMFSite :->

Please note that this is a CMF 2.1 specific issue.

CMF trunk (2.2) has a separate IOpaqueItemManager interface,
dispatchToOpaqueItems is no longer registered for IDynamicType:

http://svn.zope.org/?view=rev&rev=85187

CHANGES.txt says:
"In the long run ICatalogAware, IWorkflowAware and IOpaqueItemManager
will become deprecated. Don't expect that CMF content always implements
them."

Cheers,

Yuppie
