View observer on controller.model not working after 1.0.0rc8

I have a text area that should receive focus when the model of its associated controller changes.

Prior to rc8, I used this observer:

modelChanged: function() {
  this.set('focusing', true);
  this.$().focus();
  this.set('focusing', false);
}.observes('controller.model'),

I can't get it to work in 1.0.0 release or rc8. I have verified that an observer in the controller fires when expected:

modelChanged: function() {
  console.log('TextArtController->modelChanged');
}.observes('model'),

However I would much refer not to have the controller at that level care about the specific view (I want pull not push)

After some more digging I discovered this change note:

This severs my textarea subclass from the controller/view hierarchy.

In the latest version of ember 1.0.0 the view's TextField & TextArea where converted to components Ember.Component and since components as isolated view's not knowing about it's context the controller property does not refer to the controller anymore.

Said that, a way you could still accomplish what you are trying to do would be to use the not documented targetObject which refers to the controller in the view's surrounding context.

modelChanged: function() {
  this.set('focusing', true);
  this.$().focus();
  this.set('focusing', false);
}.observes('targetObject.model'),

Hope it helps.
