Migrating from Ember 1.8 to 1.10 - observing a property on a controller in a view stopped working



I’m migrating from Ember CLI 1.x to 2.0 and thus migrating from Ember 1.8.1 to 1.10 as well. It looks like observers in one of my views stopped working. I’ve a got the following view (simplified):

import Ember from 'ember';

export default Ember.View.extend({
    didInsertElement: function () {
        this.set('path', this.$().find('path'));
    sendingProgressDidChange: function () {
        var progress = this.get('controller.model.transfer.sendingProgress');

    receivingProgressDidChange: function () {
        var progress = this.get('controller.model.transfer.receivingProgress');

After updating Ember to 1.10, both sendingProgressDidChange and receivingProgressDidChange observers stopped working. However, if I add this.get('controller') to didInsertElement function, they work again…

Any ideas what can be wrong?


controller is a computed property perhaps there is some oddness in observing computed properties?

You may want to pass in the model explicitly to your view and change your view to a component in preparation for the deprecation of controller in 2.0.

in the controller template

{{component model=model}}


Thanks! I’ll try using component instead.
