A DESCRIPTION OF THE REQUEST :
I have 3 components in my sample application JSPinner, JButton and JLabel. I am typing a value in the JSpinner press on the button and want the label to display the current spinner value. Sometimes after a button press the label displays the old value. That means the spinner fails to commit by the time I need to use the value.

JUSTIFICATION :
The current behavior makes JSpinner very unreliable.

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
Since JFormattedTextField's default behavior is to commit on focus lost pressing on the button should always cause the JSpinner to commit since the focus is transferred to the button.
ACTUAL -
Sometimes the JSpinner doesn't commit in time.
