This app has an acceptance test tests/acceptance/application-test.js
that fails when using Ember v2.4.1
It passes with Ember v.2.3.1
The problem seems to be the with
helper when using an Ember.ObjectProxy
// application.hbs
{{model}} // => Ember.Object
{{model.name}} // => 'abc'
{{obj}} // => Ember.ObjectProxy
{{#with obj as |model|}}
{{model}} // => true (should be the same as `obj`)
{{model.name}} // => `undefined`
{{/with}}
