title: PrimeFaces.ab function
body: <p>Cant seem to find documentation for PrimeFaces.ab function</p>
  
  <pre><code>PrimeFaces.ab({source:'signupForm:signupButton'});
  return false;
  </code></pre>
  
  <p>Can anybody help me with what the code above is meant to do? It has been written against the <code>onclick</code> of a submit button.</p>
