struts的迭代标签嵌套迭代的问题

<logic:iterator>标签

class Father(){
Set children;
getter...
setter...
}

然后有List<Father> fathers;

用logic:iterator迭代fathers是没问题的，但是在迭代fathers的时候想迭代children就会提示 Cannot find bean: "father.children" in any scope
。怎么解决这种循环嵌套问题？只能用<% %>来内嵌代码吗？

代码
<logic:iterator id="father" name="fathers">
<logic:iterator id="child" name="father.children"></logic:iterator>
</logic:iterator>

Answer 1

要迭代的如果是某个属性，需要使用property,而不能直接.
<logic:iterator id="father" name="fathers">
<logic:iterator id="child" name="father" property="children">
</logic:iterator>
</logic:iterator>

Answer 2

用EL表达式很好解决${father.children}
