struts 中迭代再迭代

Question

我这么写的时候 ：<logic:notEmpty name="fatherRights"><logic:iterate id="fatherID" name="fatherRights" > <logic:notEmpty name="childRights"><logic:iterate id="childID" name="childRights"></logic:iterate> </logic:notEmpty>

</logic:iterate>    </logic:notEmpty>

Answer 1

先格式化下代码
<logic:notEmpty name="fatherRights"> 
      <logic:iterate id="fatherID" name="fatherRights" >
            <logic:notEmpty name="childRights"> 
                <logic:iterate id="childID" name="childRights">
                </logic:iterate> 
            </logic:notEmpty>
       </logic:iterate>    
</logic:notEmpty> 

Answer 2

fatherRights，childRights都在哪啊？

Answer 3

 ${childID.sname }有错，那个childID对应的对象有那个sname的属性没？有那个setSname（）方法没？没有的话就是这错了。
可以换成类似< bean:write name="childID" property="sname"/>< br>的bean标签解决

Answer 4

 把EL表达式换为< bean:write name="childID" property="sname"/>

Answer 5

<logic:iterate id="file" name="fileList">
<tr>
<html:hidden name="file" property="fileInfoId"/>

<bean:write name="file" property="fileEmpName" />
