Struts 2 nesting iterators

iterator, jsp, nested, ognl, struts2

Solution

Try this:

<s:iterator var="parent" value="parents">
    <s:iterator var="child" value="#parent.children">
        <s:property value="#child.name"/>
    <s:iterator>
<s:iterator>

Problem

I can't believe how something this simple can seem so hard to do in Struts 2. This is approximately what I would like to do as it would be done in Java. ``` for (Parent parent : parents){ for (Child child: parent.getChildren()){ System.out.println(child.getName()); } } ``` That should translate to something close to this in Stuts tags: ``` <s:iterator var="parent" value="parents"> <s:iterator var="child" value="parent.children"> <s:property value="child.name"/> <s:iterator> <s:iterator> ``` I assume parent.children should be something like ${%(#parent.children)} but I have not found a right combination of ${%(# characters to use :-). I could also use a link to a page explaining when to use which one of these.
