Default Button: switched to last focussed, but want Windows behavior, how?

Question

In a JDialog, if I add components and set one to be the default button, plus
use the Windows L&F, I expect the Windows L&F behavior, that is, as long
as I tab along buttons, an Enter will activate a button if it has focus, but if I
tab to another component, the desired default button should be visually marked (darker edge)
and an Enter should activate it.
In Plugin's JRE 1.3.1, this is not the case. The default button is reset to the last button that had
the keyboard focus.
In a JVM 1.2.2, the same code produced the expected result!
The bug db listed a few solutions, one of them was to use a Focus Manager to
track focus and then "manually" reset the default button each time the focus is not on a button.
Anyone out there with a more details on this solution?
Or perhaps, there is a better solution than tracking focus events manually?

Answer 1

Found a solution myself, which at least works for windows l&f:
make all buttons non-default capable (setDefaultCapable(false)), except for the one button, that is to be the default button. This has the unfortunate effect, that a non-default button, which has input focus, does not react to to ENTER, but the ENTER is sent to the default button instead.
So must add a keyboard action to handle the ENTER:
KeyStroke keyStroke = KeyStroke.getKeyStroke ("ENTER");
ActionListener action = new ActionListener(){
public void actionPerformed() {getMyButton().doClick();}};
getMyButton().registerKeyboardAction (action, keyStroke, WHEN_FOCUSED);
That did it for my case.
