I have a question regarding the MVC design concept. In most diagrams I have seen ( including material from the stamford lectures) there is no allowance for data to be passed back from the model to the controller. And yet data has to be passed back in order to be passed to a view,right?. Or maybe I'm mistaking data for communication? I have a private model object declared in my main controller as per recommended in the lectures ,but surely the results have to be fed back from the model to the view via the controller?
