title: Disable commandButton in JSF
body: <p>This seems like it should be pretty straightforward but I'm not feeling it.</p>
  
  <p>I have a JSF CommandButton that executes a long running serverside task (10-15 seconds).  I've seen forms where the button context changes after it's been clicked (The label on the button changes and the button becomes disabled until the processing is complete).  </p>
  
  <p>I'm using ICEFaces and have the disabled property set to a boolean on the underlying page code.</p>
  
  <p>The action listener bound to the button changes that boolean to disable it but alas, no changes on the JSP.</p>
  
  <p>Anyone?</p>
