title: Double select with struts2, jQuery and JSON
body: <p>I'm trying to use the <code>&lt;sj:select&gt;</code> as a double select, where the value from the first select should be used as a input parameter for the second select.</p>
  
  <p>First select:</p>
  
  <pre><code>&lt;s:url id="remoteurlKontor" namespace="/json" action="getKontor"/&gt;  
  &lt;sj:select  label="Kontor" 
              href="%{remoteurlKontor}" 
              id="franKontor" 
              name="franKontor" 
              onChangeTopics="reloadsecondlist" 
              list="kontor" 
              listKey="kontorKod" 
              listValue="kodAndNamn" 
              emptyOption="true" 
              headerKey="-1" 
              headerValue="Välj kontor"
  /&gt;
  </code></pre>
  
  <p>Second select</p>
  
  <pre><code>&lt;s:url id="remoteurlSektion" namespace="/json" action="getSektionskoder" /&gt; 
  &lt;sj:select  label="Sektion" 
              href="%{remoteurlSektion}" 
              id="franSektion" 
              name="franSektion"
              reloadTopics="reloadsecondlist"  
              list="sektionsKoder"
              emptyOption="true" 
              headerKey="-1" 
              headerValue="Välj Sektion"
              onSelectTopics="check"
  /&gt;
  </code></pre>
  
  <p>I want the chosen value from the first select to go as argument in <code>href="%{remoteurlSektion}"</code> so the URL will be like <code>/json/getSektionskoder.action?kontorskod=0515</code> in the second select.</p>
  
  <p>Anyone know if it's possible?</p>
