code: public static void renderClearHiddenCommandFormParamsFunction(
              ResponseWriter writer, String formName, Set dummyFormParams,
              String formTarget) throws IOException
      {
          HtmlJavaScriptUtils.renderClearHiddenCommandFormParamsFunction(writer, formName, dummyFormParams, formTarget);
      }
docs: Render the javascript function that is called on a click on a commandLink
  to clear the hidden inputs. This is necessary because on a browser back,
  each hidden input still has it's old value (browser cache!) and therefore
  a new submit would cause the according action once more!
