title: Error: $interpolate:noconcat Multiple Expressions
body: <p>Is it possible to add links with iframe with src parameters in <code>ul</code> lists generated by the API?</p>
  
  <p>URL concentration really. I have API delivering data and I wish to show it as a list with iframes.</p>
  
  <p>I have this code template:</p>
  
  <pre><code>(...)
  var getTemplate = function(contentType) {
  var  template = '&lt;ul&gt;'
              +'&lt;li ng-repeat="li in item.list" class="[[li.class]]"&gt;'
              +'&lt;iframe width="100%" height="300"'
              +'ng-src="https://myserver.com/?id=[[li.mydata]]"'
              +'&lt;/iframe&gt;'
              +'&lt;/li&gt;&lt;/ul&gt;';
          return template;
      };
  (...)
  </code></pre>
  
  <p>interpolate is set to <code>[[</code> and <code>]]</code> </p>
  
  <p>SCE secure is trusted</p>
  
  <pre><code>.config(function($sceDelegateProvider) {
    $sceDelegateProvider.resourceUrlWhitelist([
      'self',
      'https://myserver.com/**',
    ])
   })
  </code></pre>
  
  <p>When adding to template <code>&lt;h4&gt;[[li.mydata]]&lt;/h4&gt;</code> result is visible, but when to iframe ng-src - fails with this error </p>
  
  <p><code>https://docs.angularjs.org/error/$interpolate/noconcat?p0=</code></p>
