Can you please clarify what is the difference between:
tempLost.requestFocusInWindow() which was updated in the fix, and 
toFocus.requestFocusInWindow() which was not updated. As far as I 
understand the second case(when the toFocus==restoreFocusTo) is a 
component to which we should send ROLLBACK.

Best regards, Sergey.
