      <emphasis role="bold">Example:</emphasis>
 </para>

    <title>Key attributes and ways of usage</title>
    <para>The difference with the original component is that all hidden fields required for command links with the child <emphasis role="bold">
        <property>&lt;f:param&gt;</property>
      </emphasis> elements are always rendered and it doesn't depend on links rendering on the initial page. It solves the problem with invalid links that weren&apos;t rendered on a page immediately, but after some Ajax request.</para>

  <para>
      <emphasis role="bold">Example:</emphasis>
 </para>
    <programlisting role="XML"><![CDATA[<a4j:form>
	...
	<a4j:htmlComandLink action="action" value="link" rendered="#{bean.rendered}">
		<f:param ...>
	<a4j:htmlComandLink>
	...
</a4j:form>
]]></programlisting>
<para>In this example <emphasis role="bold">
        <property>&lt;a4j:htmlCommandLink&gt;</property>
      </emphasis>works as standard <emphasis role="bold">
        <property>&lt;h:commandLink&gt;</property>
      </emphasis>, but here hidden fields required for correct functionality are rendered before the first downloading of a page, though it doesn't happen if its attribute isn't set to &quot;false&quot;.</para>
