struts2 iterator capturing particular values

Hi let me tell you i searched a lot but i could not find what i wanted

here is the scenario

there is table in my jsp which is being loaded through iterator which is ArrayList<Report>

report has three attributes parameter,observation,designed

in the JSP i will show the first and third column values through iterator

<s:iterator value="ReportList" status="status" var="obj">
   <tr>
      <td><s:property value="%{#obj.parameter}" /></td>
      <td><s:textfield theme="simple" name="valOfSim" /></td>
      <td><s:property value="%{#obj.designed}" /></td>
   </tr>
</s:iterator>

Parameter           observation                designed
X                                                10
y                                                11
Z                                                12

now i have to capture the second value which has been entered kindly help!

EDIT: my code

Let me explain first preload method will be called and the values will be prepopulated through ArrayList<Obj> and then the user will enter the value for observation then am capturing that through this

<td><s:textfield theme="simple" name="obj[%{#status.index}].observation" /></td>

after that a submit button will be there onclicking that submit method of action class will be called

which prints the value entered by user (here am getting NULL)

import mypro.web.utility.SpringServiceLocator;

public class myAction extends ActionSupport implements      
ModelDriven,SessionAware,ServletRequestAware,Preparable  {
private Map<String, Object> session;
private Model  model = new Model();

public void prepare()
{

            Obj obj = new Obj();
    Obj obj2 = new Obj();
    Obj obj3 = new Obj();

    obj.setDesigned("10");
    obj.setParameter("X");
    model.getReportList().add(obj1);


    obj.setDesigned("11");
    obj.setParameter("y");
    model.getReportList().add(obj2);

            obj.setDesigned("12");
    obj.setParameter("Z");
    model.getReportList().add(obj3);
   }



  public String preload()
   {

  return "success";
   }


  public String submit()
   {


  System.out.println("------------------------------------------------------  
  &&&&&&&&&:"+model.getReportList().size());
    for(Obj obj : model.getReportList)
    {
        System.out.println("the value is to be checked"+obj.getObservation());//value which will be entered by user
        System.out.println("the value is to be checked"+obj.getRefcode()); //value which was added in the prepare method
    }



        return "success";
      } 





       public Object getModel() {

    return model;
}

Change this:

<s:textfield theme="simple" name="valOfSim" />

to this:

<s:textfield theme="simple" name="obj[%{#status.index}].observation" value="" />

This will

  1. bind your textfield to the observation field of the obj element;
  2. preserve the line number;
  3. setting the displayed value to empty (dunno why, but if this is what you want...)

This way, IF your Action has a setter for your obj element (and not only a getter), when you will submit the form containing your iterated elements, you will retrieve all the observation values inserted by the user in your ArrayList<Obj>...
