it generates the class reference and it works fine when it runs in Firefox,opera browser.
But if the generated class reference runs through Internet Explorer 9 browser. The class reference not rendered properly .It rendered properly when it runs in compatibility mode.
Please find the screenshot in which the reported issue occurs.
