RE: what setters do i implement in an indexed tag--NewBie question

John

Made few changes and code worked fine. 

Would like to extend this so that it will work for handling  Dynamic
table situation-- Let me explain

If u see in Action form reset method I initialized it to 5 (num="5 "for
testing) so the page loads with five empty rows, But we have a
requirement where the user can add more rows to the table and click
submit.

1. Action form code:

private ArrayList personList;
    
  public void reset(ActionMapping mapping, HttpServletRequest request){
     this.personList = new ArrayList();
   // String num = request.getParameter("personListLength");
     String num ="5";
        try {
            if (num != null) {
                int len = Integer.parseInt(num);
                for (int i = 0; i < len; i++)
                    this.personList.add(new PersonBean());
            }
        }catch (NumberFormatException e) {
           e.printStackTrace();
        }
    }
  public PersonBean getPerson(int ndx) {
        return (PersonBean) personList.get(ndx);
    }
  public void setPersonList(int ndx, PersonBean p) {
        personList.set(ndx, p);
    }
  public ArrayList getPersonList(){
    return this.personList;
  }

2. jsp

<TABLE id="mytable">
  <logic:present name="personList"> 
<logic:iterate id="person" name="dynaTableForm" property="personList" 
   type="com.learning.struts.PersonBean" >

  <tr>
    <td>
       <html:text name="person" property="firstName" indexed="true"/>
    </td>
    <td>
        <html:text name="person" property="phoneNo" indexed="true"/>
    </td>
  </tr>
</logic:iterate>
</logic:present>
  
</TABLE>

3.PersonBean:
public class PersonBean implements Serializable
{
  String firstName;
  String phoneNo;

  public PersonBean()
  {
    super();
  }

  public String getFirstName()
  {
    return firstName;
  }

  public void setFirstName(String newFirstName)
  {
    firstName = newFirstName;
  }

  public String getPhoneNo()
  {
    return phoneNo;
  }

  public void setPhoneNo(String newPhoneNo)
  {
    phoneNo = newPhoneNo;
  }
}

Let me know if u need any further info.

Thanks

I believe indexed attributes were first, then Arron contributed nested
and life got easier. Stick with it and don't go backwards.

Sashi, your person bean must have getName(), setName() and getPhoneNo(),

setPhoneNo().

Everybody: I haven't come across the html:taglib indexed property 
before. This seems to do what nested: tags do - is this functional
overlap?

Generally with JST taglib as well, there seems to be a wide choice of 
taglibs to use - is this going to consolidate at some point in struts' 
development?
