title: How to use af:message component
body: <p>I am working on jdev 11.1.2.2.</p>
  
  <p>I have an af:message component on my page displaying all the global messages. </p>
  
  <p>1.But the problem is it keeps showing if its error message or an information or a warning . SO i was wondering if there is a way to hide it?</p>
  
  <ol>
  <li>Is there a way to reset the message because it keeps showing the previous message even if page is refreshed ?</li>
  </ol>
  
  <p>Thanks. :)</p>
