[Zope-CMF] Re: CMFFormController & TALES

[Geoff Davis]

The TALES expressions are set up with variables that parallel those
available to the variables in actions.  "here" is unavailable, but here's
what you get:

            'object_url':   object_url,
            'folder_url':   folder.absolute_url(),
            'portal_url':   portal.absolute_url(),
            'object':       context,
            'folder':       folder,
            'portal':       portal,
            'nothing':      None,
            'request':      getattr( context, 'REQUEST', None ),
            'modules':      SecureModuleImporter,
            'member':       member,
            'state':        controller_state,

Try python:context.getParentNode().absolute_url()
