Hi

According to UEFI 2.4 spec Ch30.4 EFI_HII_CONFIG_ACCESS_PROTOCOL.CallBack(), 
"EFI_BROWSER_ACTION_CHANGED is called after the browser has changed its 
internal copy of the question value and displayed it (if appropriate)".
However, in EDKII latest code, the CHANGED callback is called even when value 
is not changed.
For example, a numeric question which is 21 and press enter without changing 
its value, the changed callback still arrives.
Is it correct?

Thanks,
Ivy Yang
