Yeah, I think my OGNL expression usage is not correct but I tried
several combination, none of them work.
If I declare my variable as:
ArrayList<ArrayList<User>> userList = new ArrayList<ArrayList<User>>();
//getter and settter
I tried this on JSP and it didn't work.
<s:iterator value="userList" id="userList" status="outerStatus">
<s:iterator value="#userList" status="innerStatus">
<s:textfield
name="userList[%{outerStatus.index}].[%{innerStatus.index}].name"/>
<s:textfield
name="userList[%{outerStatus.index}].[%{innerStatus.index}].email"/>
<s:textfield
name="userList[%{outerStatus.index}].[%{innerStatus.index}].address"/>
</s:iterator>
</s:iterator>

What do you have inside the iterator tag?? Hard to diagnose without
knowing what you have. Some possible causes:
A a possible OGNL expression error inside your iterator tag.
If the Sample objects are not built-in java objects (String, Date..) you
might be having type conversion problems?
Are you sending the information back to the same action or is there a
possible mix-up in the attributes of your tags

Subject: Nested iterator struts 2.1.6 -- automatically rebuild the
collection
Hi,
Using <s:iterator ..> tag, how do you instruct struts to rebuild the
collection automatically?
I have a List of List of Sample objects
I use <s:iterator > tag to loop through and display data for user to
make changes
The displaying part is OK; however, when the form is submitted, the List
of List of Sample objects is not populated.
In Struts 1.x, the tag <logic:iterator > was used and if we add
indexed=true for each element inside the <logic:iterator > tag, Struts
automatically rebuild the collection. Is there a way that it can
accomplish with <s:iterator>?
Thank you.
