Reading the documentation, i found out why i could not set permissions on the before_publishing_traverse. It seems that at this point, getting SecurityGetUser its not reliable. So, i was thinking of a way to test for if a role is valid to access an object. Maybe Security.validate() or something, i dont know. And if theres a hook for testing when a property is accessed, like testing for some condition before returning title_or_id. Something like __before_property_access__.
