I've got part of the answer.  The JFormattedTextField apparently
changes a "value" attribute when the field commits.  I can't find
anywhere that this is documented; I found it by looking at the
source code for the GNU Classpath implementation of JFormattedTextField,
and experimentally determined that the Sun implementation does it
as well.  However, the getOldValue() and getNewValue() methods of
the PropertyChangeEvent both return null, which seems broken.

The bigger problem is that when using a MaskFormatter, the field
doesn't seem to commit when return is pressed (and the contents are valid),
though it does commit if it loses the focus because I click in a
different field.  Ugh.  Any way to force it to commit on the return
key?

Thanks,
Eric
