title: Update an edittext inside a dialog, value gets updated but not the text
body: <p>I have a edittext which I am displaying inside a dialog, but later (before the dialog is closed) I am updating the value inside it but when I do this I can read the correct new value from .gettext() but the edittext is still empty, why?</p>
  
  <p>This is my code:</p>
  
  <pre><code>public void setText(String url) {
      response.setText("http://xxxx/" + url);
      response.invalidate();
      response.selectAll();
  }
  </code></pre>
  
  <p>It feels like I've tried everything, searched for hours for a answer but nothing that I've tried has worked. :(</p>
  
  <p>Is there any quick solution to this problem or do I really need to redraw the whole custom dialog?</p>
