How are the person objects being populated?
here is the sample configuration from showcase:
<action name="enterPersonsInfo" method="input"
class="org.apache.struts2.showcase.conversion.PersonAction">
<result>enterPersonInfo.jsp</result>
</action>
<action name="submitPersonInfo" method="submit"
class="org.apache.struts2.showcase.conversion.PersonAction">
<result>showPersonInfo.jsp</result>
<result name="input">enterPersonInfo.jsp</result>
</action>
<action name="showPersonJspCode">
<result type="plainText">/conversion/enterPersonInfo.jsp</result>
</action>
<action name="showPersonActionJavaCode">
<result type="plainText">/conversion/PersonAction.java.txt</result>
</action>
<action name="showPersonJavaCode">
<result type="plainText">/conversion/Person.java.txt</result>
</action>
here is enterPersonInfo.jsp which is used for all results to/fro
enterPersonsInfo action input method

An example populating a list of object (Person.java) into Struts' action
(PersonAction.java)
<p/>
See the jsp code <s:url var="url" action="showPersonJspCode"
namespace="/conversion" /><s:a href="%{#url}">here.</s:a><br/>
See the code for PersonAction.java <s:url var="url"
action="showPersonActionJavaCode" namespace="/conversion" /><s:a
href="%{#url}">here.</s:a><br/>
See the code for Person.java <s:url var="url" action="showPersonJavaCode"
namespace="/conversion" /><s:a href="%{#url}">here.</s:a><br/>
<p/>
<s:actionerror />
<s:fielderror />
<s:form action="submitPersonInfo" namespace="/conversion" method="post">
<%--
The following is done Dynamically
--%>
<s:iterator value="new int[3]" status="stat">
<s:textfield label="%{'Person '+#stat.index+' Name'}"
name="%{'persons['+#stat.index+'].name'}" />
<s:textfield label="%{'Person '+#stat.index+' Age'}"
name="%{'persons['+#stat.index+'].age'}" />
</s:iterator>
<%--
The following is done statically:-
--%>
<%--
<s:textfield label="Person 1 Name"
name="persons[0].name" />
<s:textfield label="Person 1 Age"
name="persons[0].age" />
<s:textfield label="Person 2 Name"
name="persons[1].name" />
<s:textfield label="Person 2 Age"
name="persons[1].age" />
<s:textfield label="Person 3 Name"
name="persons[2].name" />
<s:textfield label="Person 3 Age"
name="persons[2].age" />
--%>
<s:submit />
</s:form>
</body>

package org.apache.struts2.showcase.conversion;
import java.util.List;
import com.opensymphony.xwork2.ActionSupport;
/**
*
*/
public class PersonAction extends ActionSupport {
private List persons;
public List getPersons() { return persons; }
public void setPersons(List persons) { this.persons = persons; }
public String input() throws Exception {
return SUCCESS;
}
public String submit() throws Exception {
return SUCCESS;
}
}
the important bits are jsp reference to persons list here
<s:iterator value="new int[3]" status="stat">
<s:textfield label="%{'Person '+#stat.index+' Name'}"
name="%{'persons['+#stat.index+'].name'}" />
<s:textfield label="%{'Person '+#stat.index+' Age'}"
name="%{'persons['+#stat.index+'].age'}" />
</s:iterator>
which references and iterates thru the List of persons from PersonAction
private List persons;
Action class does push its attributes on to OGNLstack so a reference such as
"%{'persons['+#stat.index+'].name'}"
works
provided you have set stat to be the 'status' index
