title: Chain multiple expressions in AngularJS ng-class
body: <p>I'm trying to chain two different expressions into an <code>ng-class</code>, one of them have a filter applied to it, something like:</p>
  
  <pre><code>&lt;body ng-class="controller | camel2hyphens" ng-class="{overflow: isOverflow}"&gt;
  </code></pre>
  
  <p>But Angular only uses one of the them (which makes sense).</p>
  
  <p>I've tried using an array of expression this way:</p>
  
  <pre><code>&lt;body ng-class="[(controller | camel2hyphens), {overflow: isOverflow}]"&gt;
  </code></pre>
  
  <p>But the CSS class that is set is:</p>
  
  <pre><code>class="login-controller [object Object]"
  </code></pre>
  
  <p>Is there any way to accomplish this with <code>ng-class</code> (without writing a method in the Controller with the logic).</p>
  
  <p>Thanks!</p>
