title: Why is the action attribute of a commandButton not working with ajax render
body: <p>This commandButton is working:</p>
  
  <pre><code>&lt;h:commandButton id="button_updateIt" value="#{i18n.button_update_it}"
      action="#{masterBean.update()}"&gt;         
  &lt;/h:commandButton&gt;
  </code></pre>
  
  <p>This ajax call is working:</p>
  
  <pre><code>&lt;h:commandButton id="button_updateIt" value="#{i18n.button_update_it}"&gt;
      &lt;f:ajax event="click" render=":form_2:updateMe" /&gt;            
  &lt;/h:commandButton&gt;
  </code></pre>
  
  <p>Why is the action attribute combined with ajax not working?</p>
  
  <pre><code>&lt;h:commandButton id="button_updateIt"
      value="#{i18n.button_update_it}"
      action="#{masterBean.update()}"&gt;
  
      &lt;f:ajax event="click" render=":form_2:updateMe" /&gt;
  
  &lt;/h:commandButton&gt;
  </code></pre>
  
  <p>I use jsf version 2.1.1 and java 1.7.0 and GlassFish Server 3.1.2 (build 23)</p>
