ViewController: how to access view's childs?

Throughout the life of the view controller it's possible that references come and go, so I don't think adding methods for references is appropriate.

That's because you could add components at run time?

One of the things I hate the most of MVC is the use of strings to get references to components via "ref" or someComp.down("xxxx").

Chances to reconsider a getter for those references?

I would like this:

this.getView().getUserName()...

than

this.getReference("userName")...

even if former is more verbose.

Nevertheless the more I read about ExtJS 5 more I like it.

Regards.
