title: Page does not change after I set an option button with HtmlUnit
body: <p>I am using HtmlUnit to navigate through the Web of knowledge web page. I am using the code below to set an option button so that results on the page would be sorted appropriately. Unfortunately, nothing happens when I execute the code. Results on the page remains sorted in the same way as they ware before.</p>
  
  <pre><code>HtmlSelect ssort = (HtmlSelect) pageX.getFirstByXPath("//*[@id=\'topNavBar\']/tbody/tr/td[3]/form/select");
  
  HtmlOption optionA = ssort.getOptionByValue("LC.D;PY.D;AU.A;SO.A;VL.D;PG.A");
  
  ssort.setSelectedAttribute(optionA, true);
  
  ssort.click();
  </code></pre>
  
  <p>I debuged the code and there is no errors. Do you have any idea what am I doing wrong?</p>
