 * This view will register itself as listener to the {@link BadgeService} service.<br />
 * When there is an update to the badges this view will manage the visibility change of
 * its badge-view.<br />
 * It is also used to mark the badge as read. When the user clicks to open a panel, the
 * {@link #markAsRead()} should be
 * called and this method will first hide the badge view and secondly it will invoke the
 * {@link BadgeService#markAsRead(Filters)}.
