     * Because of the way that STRUTS works, if the user does not check the enabled box,
     * or unchecks it, setEnabled() is never called, thus we must monitor setEnabled()
     * to see if it doesn't get called. This must be accessible, as ActionForms need to
     * know about it -- there is no way we can tell whether we are about to be passed to
     * an ActionForm or not.
     *
     * Probably a better way to do this, but I can't think of one.

     * TODO: Hey richard Jody here - Struts knows that boolean properties are
     * not set if the user does nothing. Apparently that is why the reset
     * method exists.
     * Reset is called *every* time on ActionForm. Before the populate
     * process has a go at things.
     *
     * The problem is that reset() retrieves the WFS's config enabled value
     * and uses that to pre-populate the form. Thus, if they deselect it, setEnabled is
     * never called, and enabled still remains true. The way I have done it isn't simple,
     * but it works just fine.
