------解决方案--------------------
The requested list key '#{1:'管理员'，2:'会员' }'
把里面的，换成英文版的；
仔细检查，别再把中文的字符和英文的字符混淆到一块去；
------解决方案--------------------
参考一下：
<s:select list="{'aa','bb','cc'}" theme="simple" headerKey="00" headerValue="00"></s:select>
你的异常好像说list无法循环，你的select list必须是一个collection/array/map/enumeration/iterator 这些类型。
