Hi Li,
Thanks ... Unfortunately, In my case, Map represents various java model
classes at run time ( User, Employee etc ). So I will get the values in a
Single Hash Map ( Using BeanUtils.describe )..
But Yes... as you said, By default struts 2 determine the Object Type using
Type of the attribute. In My case, It is always plain Object :(...
As of now, i process the Map in my action class to do the type conversion.
just thinking is there any other better way ..
Regards,
Sathish Kumar T.
