    <para>
          The <emphasis role="bold"><property>&lt;a4j:commandButton&gt;</property></emphasis>component is very similar to JSF <emphasis role="bold"><property>&lt;h:commandButton&gt;</property></emphasis>, the only difference is that an Ajax form submit is generated on a click and it allows dynamic rerendering after a response comes back.
