title: Fixture Adapter filtering
body: <p>I'm currently writing an application relying on fixture data (REST API will follow) which I have some problems or misunderstandings with.</p>
  
  <p>I'm displaying a lot of products in different categories and my index route e.g. should present only products containing a special flag.</p>
  
  <pre><code>TM.IndexRoute = Ember.Route.extend({
  model: function() {
      return TM.Product.all().toArray().filter(function(item){
                          return item.get('featured') === 1;
                      });
  }});
  </code></pre>
  
  <p>My problem: After loading the index route for the first time the model is empty. Switching to a different route and back to the index route loads the data as expected. I have the same issue with other filtering and no clue why this happens. It always works instantly without the filter - so my bindings have to be right.</p>
  
  <p>I'm using the latest versions of ember (1.0.0-rc2) and ember-data (rev 12).</p>
  
  <p>thx in advance.</p>
