Usage

/**
 *  Reloads the preferences from the PageContext into the WikiContext.
 *  /*from  w ww .ja v  a2 s .co  m*/
 *  @param pageContext The page context.
 */
// FIXME: The way that date preferences are chosen is currently a bit wacky: it all
//        gets saved to the cookie based on the browser state with which the user
//        happened to first arrive to the site with.  This, unfortunately, means that
//        even if the user changes e.g. language preferences (like in a web cafe),
//        the old preferences still remain in a site cookie.
