Question

This doesn’t seem to work
http://jsfiddle.net/8haXN/7/

App.president = Ember.Object.create({
    name: "Barack Obama",
    name2: "George Bush"
});

App.country = Ember.Object.create({
    presidentNameBinding: 'App.president.name'
});

App.country.set('presidentNameBinding', 'App.president.name2');
App.country.presidentName //stil returns 'Barack Obama'

What I’m really trying to do is to change the contentBinding of a CollectionView from one ArrayController to another. Is that possible or is it a bad idea?

Answer 1

You will have to manually bind this way:

App.country.bind('presidentName', Em.Binding.from('App.president.name2'));

Here’s the jsfiddle: http://jsfiddle.net/efPGF/

To read more about bindings, I recommend looking at the old Sproutcore wiki: http://wiki.sproutcore.com/w/page/12412963/Runtime-Bindings. Just remember to change SC prefix to Ember.
