值栈显示问题（高版本要求属性为public(有些标签要求有变化)）

报错：

<s:select  ，<s:checkList      struts标签

tag 'select', field 'list'The requested list key 'qTypes' could not be resolved as a collection/array/map/enumeration/iterator type

 

 

 

这种问题:

1,高版本的struts标签<s:select> 中的list要求不为null

public List<DicContentEntity> approveStatusList = new ArrayList<DicContentEntity>();

加set get

2,一般是后台属性是private，而get，set方法是public,此时应该把属性改为public

<s:debug>可以直接看到只要有属性有这种问题都会显示
