title: Uncaught TypeError: this.transitionTo is not a function
body: <p>I just upgraded my application to <code>ember 2.1</code> and am getting this error in my web browser console:</p>
  
  <pre><code>Uncaught TypeError: this.transitionTo is not a function
  </code></pre>
  
  <p>In my url, I have a variable named <code>direction</code>:</p>
  
  <pre><code>http://localhost:4200/plates/new?direction=plates
  </code></pre>
  
  <p>Then I build this into my controller:</p>
  
  <pre><code>export default Ember.Controller.extend({
      queryParams: ['direction'],
      direction: null,
      actions: {
          lastpage(){
              this.transitionTo(this.get('direction'));
              },
         save(...){
              },  
  
          },  
      }); 
  </code></pre>
  
  <p>This used to work before my upgrade. What depreciated / how do I fix this error?</p>
