I thought i''d share this snippet with others on the list who want to
use the facebooker before filters but also want their app to run on a
non-facebook format too:
before_filter {|controller|
ensure_application_is_installed_by_facebook_user if controller.params
["format"] == "fbml" }
This simply wraps the facebooker before_filter in a proc and only
executes it if the format is "fbml"
Hope that is helpful.
