title: The attribute update is not defined in the component commandButton
body: <p>I have this JSF commandButton which I use to delete rows from table:</p>
  
  <pre><code>&lt;h:commandButton id="deleterow" value="HiddenDelete"  action="#{BatteryProfileTabGeneralController.saveData}" style="display:none" update="growl"&gt;
      &lt;f:ajax render="@form" execute="@form"&gt;&lt;/f:ajax&gt;
  &lt;/h:commandButton&gt;
  </code></pre>
  
  <p>In Netbeans 7.3 I get this error:</p>
  
  <pre><code>The attribute update is not defined in the component commandButton
  </code></pre>
  
  <p>I use <code>update</code> attribute to display message when I successfully delete row. Can I replace this attribute with similar attribute?</p>
