Thanks! So this works, but I had to wrap each object in an Ember.Object.
Ember.ArrayProxy.create({
content: [
Ember.Object.create({ id: 1, title: 'asdf' }),
Ember.Object.create({ id: 2, title: 'yuio' }),
]
});
This works, but feels wrong for some reason. Am I going about writing the component and/or testing it the wrong way?
