Not able to submit Ordered List even using Indexed property

here my list is getting fetched successfully and values are getting displayed in the in text field,
But when i'm editing the values in the textboxes , and on submitting the form , the list values are
not submited in the action

heres my ActionForm,

package com.actionform;

import com.VO.StudentVO;
import java.util.ArrayList;
import java.util.List;
import javax.servlet.http.HttpServletRequest;

import org.apache.struts.action.ActionErrors;
import org.apache.struts.action.ActionMapping;
import org.apache.struts.action.ActionMessage;

public class MainForm extends org.apache.struts.action.ActionForm {
    
    
   
    private List<StudentVO> students;

public MainForm() {
        super();
        this.students = new ArrayList<StudentVO>();

}

@Override
    public void reset(ActionMapping mapping, HttpServletRequest request){

}

@Override
    public ActionErrors validate(ActionMapping mapping, HttpServletRequest request) {
        ActionErrors errors = new ActionErrors();
        if (getName() == null || getName().length() < 1) {
            errors.add("name", new ActionMessage("error.name.required"));           
        }
        return errors;
    }

public List<StudentVO> getStudents() {
        return students;
    }

public void setStudents(List<StudentVO> students) {
        this.students = students;

}

public StudentVO getStudent(int index) {    
        return this.students.get(index);
    }

public void setStudent(int index, StudentVO studentVO) {
        this.students.set(index, studentVO);
    }
    
    
   
}

heres my Struts Config Mapping,

Check the rendered HTML...

i figured out the problem

now i did some changes in jsp that is as follows

than i did a change in ActionForm for the getter method of student , which is

by doing these above changes i'm able to populate the studentId's and student names in the text field , as well as if i change the names or the id's in the text field
i'm able to submit it successfully and those changed field i'm able to see in the action .

But here is a question, here in the action form in the getter of student i have hardcoded the number 7 which is the list size when i set the list in setter.

but if i don't want to hard code the value , what if my list is dynamic, this list can be 7 or more or even less , than what to do ??

please give some suggestion

I'M EXTREMELY SORRY FOR ASKING SUCH A STUPID QUESTION, I FIGURED IT OUT, I CHANGED MY GETTER METHOD OF student in ActionForm , which is as follows

now it works perfectly fine , thank you

Correct--that's why I wanted you to look at the rendered HTML, so you'd see you were duplicating the work the "indexed" attribute already does for you.

It's a list--it's dynamically sized.I'm not sure what you're trying to do here.

Edit: Sorry, didn't see you'd already answered your own question.

Glad you figured it out :)
