I recommend using Passive View, where the view has as little logic as possible.
Your controller can get access to any of the widgets in the view, via ComponentQuery. You can then write code in the controller to set or read values from the view.
You can also use the form.loadRecord() method to load a model into a view/form.
The widgets in the view communicate with the controller by raising events that are then handled by the controller.
You should load all of your controllers when the application starts.
Your controller should only have event handlers, and should never use the refs array or getView() functions (else you won’t be able to control multiple instances of the same view).
Create and destroy your views at will. Pass in callback functions to communicate from parent to child view.
