Hey,
That's one way. But, since the ModelLocator is already Bindable, you
don't need to add event listeners for data changes. As an alternative
you can bind {} ModelLocator variables to the dataProviders in your
components. When the data in the model variables is changed, the
binding mechanism automatically updates the view. If you need to do
something in the view, when the data is updated, you can always use the
valueCommit event on the bound control.
Next stop; ApplicationController and Commands.
