Are you sure? I've been putting 'c' assignments in
BaseController.__call__ without problem, for things like the default
page title and breadcrumbs.
The problem here seems to be that BaseController.__call__ is not
called at all. If .__before__ doesn't work, I think you'll have to
override WSGIController._dispatch_call() (the superclass of
BaseController, defined in pylons.controllers.core), which is what
does the normal action lookup and calling.
