When I take out "hideonline" from user_form.htm, I got NullPointer because:
u.setViewOnlineEnabled((request.getParameter("hideonline").equals("0"));
You can avoid this problem by changing things around when doing
string comparison.
u.setViewOnlineEnabled("0".equals(request.getParameter("hideonline")));
