的问题
我尝试按照以下示例运行代码：
http:// /www.mkyong.com/struts2/struts-2-sselect-drop-down-box-example/
但收到错误消息：
Error 500: tag 'select', field 'list', name 'yourSearchEngine': The requested list key 'searchEngine' could not be resolved as a collection/array/map/enumeration/iterator type. Example: people or people.{name} - [unknown location]
我该如何修复它？ 谢谢和问候！

您的操作需要一个名为 yourSearchEngine 的公共方法，其类型为集合/数组/映射/枚举/迭代器。或者是上述类型的名为 yourSearchEngine 的私有方法，并定义了适当的 getter。还要确保您的搜索引擎已初始化。
Your action need either a public method called yourSearchEngine which is of type collection/array/map/enumeration/iterator. Or a private method called yourSearchEngine of the aforementioned types with a proper getter defined. Also ensure yourSearchEngine has been initialized.
这意味着在您看来，无论您在何处尝试迭代 ArrayList 或任何其他集合，字段“list”都不会获取任何集合。
可能您正在尝试迭代
我也遇到这个问题了。还可以尝试清理您的项目。
This means in your view, whereever you are trying to iterate an ArrayList or any other collection, the field "list" is not getting any Collection.
May be you are trying to iterate a List in
<s:select>.I got this problem too. Also try cleaning your Project.
