The underlying problem is that if a HTML widget has no value, then it
does not get submitted at all. Which includes an unchecked checkbox.
Struts needs to set the ActionForm properties from the submit, but if
the checkbox isn't there it can't, and so the checkbox could end up null
(rather than false).
Struts calls reset before setting the properties from the submit, so by
setting the checkbox to the default state (be it true or false), it will
either remain that way or be changed to reflect the user gesture.
