First of all, you shouldn't do that.

You are coupling controller, view and model logic in your controller action. You shouldn't "prepare things for the view" in the controller, but rather just "prepare the context for the view". That meaning, if you're in a inner context (such as one individual customer), the controller should set this up. But NEVER build data structures that are specific for one view.

You should use more of the TT programming language for such things. In a lot of cases, your controller action will be just empty, because context was defined in an earlier chained action, and you just need to dispatch to one specific view (most of the time, to one specific template).

That means that you are going to do a lot of "search" calls directyly in your template, but THAT'S OK!!. That's how MVC is supposed to be, remember. It's not a layered schema, it's a triangle.

Which means, the model is accessed both by the controller and the view, and the controller just dispatches to the view. It is very important that you do not couple the controller to the view, otherwise, implementing an alternative view (RSS, ATOM, email) will be very hard.
