[Zope-CMF] adding items to the TALES namespace for actions

[Rocky Burt]

Hi all,

I'd like to add a new variable to the TALES namespace for all actions
(for all existing action providers) on a CMF 1.6.0 site.  We basically
have a view that provides some global vars that we'd like to expose.

Does anyone know of a sensible way to do this without monkey patching
CMFCore.Expression.createExprContext ?

Or perhaps suggest a different way of accomplishing what we need?

Thanks,
Rocky
