FULL OPERATING SYSTEM VERSION :
Microsoft Windows 2000 [Version 5.00.2195]

A DESCRIPTION OF THE PROBLEM :
JSpinner updates its field using the buttons or keys. A
single event occurs if the button or key is hit once but if
the key or button is held down many events occur in rapid
succession. I am trying to write an application that shows
a modal dialog, stating that the spinner is not the correct
item to be used next in a sequence of instructions. The
dialog is modal. The JSpinner generates many events from
holding the button (it may actually generate infinite
events as it appears the button is "stuck" on the down
postion. This is evidenced by the fact that if you remove
the listener then hide the dialog, the spinner spins out of
control.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
1. Press and hold a JSpinner button
2. On a ChangeEvent, show a modal dialog
3. hide the dialog.

EXPECTED VERSUS ACTUAL BEHAVIOR :
1. If you don't remove the listener, the dialog appears
over and over again.
2. If you remove the listener the button is "stuck".

I would like to be able to halt the changes so the spinner
can complete one full cycle release its button and receive
no more events.

REPRODUCIBILITY :
This bug can be reproduced always.

            public void stateChanged(ChangeEvent e){
dialog.pack();
//jSpinner.removeChangeListener
(jSpinner.getChangeListeners()[0]); // this makes the button stick.

            }

        setVisible(true);

        spinControl s =

}

CUSTOMER WORKAROUND :
I just won't be able to react to the user pressing the spinner when they are not supposed to. Ultimately it makes the application inconsistent.
