Ember.js: Models: Challenge: ObjectController and ArrayController

http://teamtreehouse.com/library/emberjs/models/challenge-objectcontroller-and-arraycontroller

"In the Animal Shelter app, we've added a property to the kitten objects called cutenessRating. Make a KittensController that sorts the kittens by their cuteness by default."

Following the code I input for controllers/posts.js, I put in

// your code here
AnimalShelter.KittensController = Ember.ArrayController.extend({
  actions: {
    sortByCutenessRating: function() {
      this.set('sortProperties', ['cutenessRating']);
    }
  }
});

I get an error message stating "Bummer! You need to set the sortProperties property within the controller."

Is this a bug or is there something incorrect in the code I put in?

Change you sortByCutenessRating to sortByTitle. Before the actions label add the default 'sortProperties: ['cutenessRating'],'.

AnimalShelter.KittensController = Ember.ArrayController.extend({
  sortProperties: ['cutenessRating'],
  actions: {
    sortByTitle: function() {
       this.set('sortProperties', ['cutenessRating']);
    }
  }
});

Actually, there is no need to change the function name to sortByTitle. Just set sortProperties as Jeremy suggests.

AnimalShelter.KittensController = Ember.ArrayController.extend({
  sortProperties: ['cutenessRating'],
  actions: {
    sortByCutenessRating: function() {
       this.set('sortProperties', ['cutenessRating']);
    }
  }
});

I agree with Chris no need to sortByTitle this worked for me too; AnimalShelter.KittensController = Ember.ArrayController.extend({ sortProperties: ['cutenessRating'], actions: { sortByCutenessRating: function() { this.set('sortProperties', ['cutenessRating']); } } });
