title: How to programmatically ajax-update specific component in backing bean
body: <p>Is there a way to ajax-update a specific component such as a <code>&lt;h:form&gt;</code> in backing bean?</p>
  
  <p>I tried the following using <a href="http://www.primefaces.org/docs/api/3.4/org/primefaces/context/RequestContext.html#execute%28java.lang.String%29" rel="noreferrer"><code>RequestContext#execute()</code></a>,</p>
  
  <pre><code>RequestContext context = RequestContext.getCurrentInstance();
  context.execute("monitorVehicleForm.update()");
  </code></pre>
  
  <p>however that didn't seem to have any effect.</p>
