OK, here is my first unsuccessful attempt. I've never used advises
before so I'm not even sure it makes sense. 

--8<---------------cut here---------------start------------->8---
(defun jc-change-agenda-files ()
  (make-local-variable 'org-agenda-files)
  (setq org-agenda-files '('"~/org/orgfiles/planning.org")))

(advice-add 'cfw:open-org-calendar :before
	      'jc-change-agenda-files)
--8<---------------cut here---------------end--------------->8---

When I run cfw:open-org-calendar, I see entries from all my agenda
files. However, without the make-local-variable part, I only get the
entries from planning.org but that's not what I want since I don't want
to change org-agenda-files for the other agenda views.
