Which form componnent had focus when form was submitted?

[Warren Bell]

Is there a way to figure out in a forms onSubmit which text field or
button had focus when the form is submitted. I have done something in js
to achieve this, but wanted to see if there was something already built
in Wicket. I am limited to using form submit only no Ajax. Windows CE is
having problems with some of the Ajax I tried to use.
 
Thanks,
