javax.servlet.ServletException: Cannot get value for expression

访问页面时出现这样的错误：
javax.servlet.ServletException: Cannot get value for expression '#{areaBean.secArea.areaId}'

因为我的用户验证还没做好，所以我想直接访问AreaManage.jsp页面，它报错说：得不到areaId的值，这个值是一项输入值，用于查询，我连页面都没进去，当然没有这个值了。所以我想问下  如何直接访问areaManage.jsp  该页面有list 是不是意味着访问这个页面时就要查询一下数据库  这个应该怎么做？？
