title: Primefaces p:fileupload oncomplete does not work in IE 10
body: <p>I use primefaces + jsf web project.</p>
  <p>In index.xhtml JS:</p>
  <pre class="lang-js prettyprint-override"><code>function showStatus() {
      statusDialog.show();
  }
  
  function hideStatus() {
      statusDialog.hide();
  }
  </code></pre>
  <p>In index.xhtml PF:</p>
  <pre class="lang-html prettyprint-override"><code>&lt;p:ajaxStatus onstart=&quot;statusDialog.show();&quot;
              onsuccess=&quot;statusDialog.hide();&quot; /&gt;
              
  &lt;p:fileUpload label=&quot;#{msg['cms']['selectFile']}&quot;
              uploadLabel=&quot;#{msg['cms']['upload']}&quot;
              mode=&quot;advanced&quot; multiple=&quot;true&quot;
              cancelLabel=&quot;#{msg['framework']['cancel']}&quot;
              fileUploadListener=&quot;#{storageController.handleMultipleFileUpload}&quot;&gt;
  &lt;/p:fileUpload&gt;
  </code></pre>
  <p>When I trigger an AJAX call through <code>&lt;p:commandButton</code>, the <code>&lt;p:ajaxStatus</code> does not work, but still shows the following loading image:</p>
  <p><img src="https://i.stack.imgur.com/ESvhr.png" alt="enter image description here" /></p>
  <p>It should hide the <code>statusDialog</code> when file upload is complete.</p>
