title: JSF: make f:facet header as commandLink
body: <p>jsf:</p>
  
  <pre><code>&lt;rich:dataTable&gt;
  ...
      &lt;h:column&gt;
       &lt;f:facet name="header"&gt;
        &lt;h:commandLink action="fileSearchSort" styleClass="theader"&gt;
         Name
        &lt;/h:commandLink&gt;
       &lt;/f:facet&gt;
         #{f.name}
      &lt;/h:column&gt;
  ...
  &lt;/rich:dataTable&gt;
  </code></pre>
  
  <p>if do this:</p>
  
  <pre><code>...
      &lt;h:column&gt;
        &lt;h:commandLink action="fileSearchSort" styleClass="theader"&gt;
         &lt;f:facet name="header"&gt;
          Name
         &lt;/f:facet&gt;
        &lt;/h:commandLink&gt;
         #{f.name}
      &lt;/h:column&gt;
  ...
  </code></pre>
  
  <p>that label "Name" in header is dissappeared.</p>
  
  <p>Is it possible to do whole <code>f:facet</code> header as <code>commandLink</code>?</p>
  
  <p>thanks.</p>
