我在jsp中加上<s:select>的标签在页面怎么什么内容都不显示了

删掉标签之后就显示了

这是错误信息:
ervlet.service() for servlet [jsp] in context with path [/day69] threw exception [tag 'select', field 'list': The requested list key 'custSource' could not be resolved as a collection/array/map/enumeration/iterator type. Example: people or people.{name} - [unknown location]] with root cause
tag 'select', field 'list': The requested list key 'custSource' could not be resolved as a collection/array/map/enumeration/iterator type. Example: people or people.{name} - [unknown location]

后台有异常
s: 这个是struct的吧

<option value="对应主见id">用户看到的信息</option> 若当前select在表单里，直接提交就可以获取到内容，服务器端以select的name属性接收，就可以接收到当前的对应主见id 用javascript提交也可以
