title: Primefaces - Do not display message for required fields, just hightlight border
body: <p>I have a Primefaces 3-field form and a <code>&lt;p:messages&gt;</code> tag to show some server-side validation messages. But I don't want to display the client-side messages related to the <code>required="true"</code> option, just highlight the input field with red.  </p>
  
  <p>Is there a way to do it with Primefaces?</p>
