Here's the last paragraph of the JavaDoc for the reset() method
(emphasis in original):
"This method is *not* the appropriate place to initialize form value
for an "update" type page (this should be done in a setup Action). You
mainly need to worry about setting checkbox values to false; most of
the time you can leave this method unimplemented."
You say the ActionForm is "just a class" with "a simple lifecycle".
That "lifecycle" is more than just a sequence of method invocations,
but also the expected behavior of each of those invocations. The
documentation ("lifecycle specification") clearly defines that the
only behavior that is expected during the invocation of the reset()
method is to set checkbox values to false.
