Calling reset is a prelude to autopopulation. Unless the request is
being redirected along the way, this should just put the same values
back into the ActionForm.
Reset must be called to ensure that the properties for some controls,
like checkboxes, are set correctly. The default reset does nothing. It
is really only needed for checkboxes.
