Fixed version (ground truth):

      }
 else       if (validActions.size() == 1) {
        ActionValue av=validActions.get(0).getValue();
        if (av instanceof URLValue) {
          return getJsURLRedirect((URLValue)av);
        }
 else         if (av instanceof ScriptValue) {
          return ((ScriptValue)av).getScript();
        }
      }
 else {
        hasMultipleMenu=true;
        return MultiActionValuesScriptGenerator.getJSContent((MultipleActions)ac,getULocale());
      }
    }
