GWT Add-In usage in UFT 12.51

Hi,

I am working on an application which was developed on GWT framework. Few objects like text box, Check box are getting identified with or without enabling GWT Add-in on the Add-In manager. But there are few objects like list box, button and Radio Group are  NOT getting identified as expected ( WebList as WebTable, WebButton as WebElement) eventhough GWT add-in has been enabled. So, if anyone have worked or have good idea on the usage of GWT Add-in then please share the information.

Thanks & Regards,
Santhosh Kumar.
