title: Ember.js - "Cannot perform operations on a Metamorph that is not in the DOM" caused by template
body: <p>I've been having an issue with Ember.js throwing the error:</p>
  
  <pre><code>Uncaught Error: Cannot perform operations on a Metamorph that is not in the DOM.
  </code></pre>
  
  <p>I found <a href="https://stackoverflow.com/questions/10726460/cannot-perform-operations-on-a-metamorph-that-is-not-in-the-dom-in-ie8-on">these</a> <a href="https://stackoverflow.com/questions/16676663/ember-js-cannot-perform-operations-on-a-metamorph-that-is-not-in-the-dom">two</a> SO questions, both of which involve direct manipulation of the DOM, which is not the case in my app. Searching for the error message also returns numerous Github issues related to the same type of direct DOM manipulation.</p>
