Re: Why does struts assign indexedValues from 2nd index.......please help
I've tried another example also...
ListForm.java
=
package com.myapp.struts.formbeans;
import org.apache.struts.action.*;
import javax.servlet.http.*;
import java.util.*;
/**

*/
public class ListForm extends ActionForm {
private int size = 3;
private List friends = new ArrayList(size);
public List getFriends( ) {
return friends;
}
public String getFriend(int index) {
if (index = friends.size( )) {
friends.add(index, new String());
}
return (String) friends.get(index);
}
public void setFriend(int index, String name) {
System.out.println(size: +friends.size()+- index:+index);
}
public void reset(ActionMapping mapping, HttpServletRequest request) {
// prepopulate the list with empty strings
friends = new ArrayList( );
for (int i=0; isize;i++) friends.add();
}
}
pollsForm2.jsp
==
h2List Form Test/h2
html:form action=/multipleForm method=get
Who are your 3 friends:br /
Friend 1: html:text property=friend[0]/br /
Friend 2: html:text property=friend[1]/br /
Friend 3: html:text property=friend[2]/br /
Friend 3: html:text property=friend[3]/br /
Friend 3: html:text property=friend[4]/br /
Friend 3: html:text property=friend[5]/br /
Friend 3: html:text property=friend[6]/br /
Friend 3: html:text property=friend[7]/br /
html:submit/
/html:form
The output while setting the request parameter values is as follows..
size: 3- index:0
size: 3- index:4
size: 3- index:3
size: 3- index:6
size: 3- index:7
size: 3- index:5
size: 3- index:1
size: 3- index:2
We can see here also struts is not settings the parameter values in order (
i mean according to the index ). It's trying to set object at 0 index,
jumping by trying to set at 4 index.
Why is this so??is this problem solved in struts 1.2.9 ( i'm
currently using 1.2.7) ??
Any personal suggestions are also appreciated..
Friends, please help

The html-form looks like below
html:form method=get action=/multipleForm
html:text property=pollQuestion
Re: Why does struts assign indexedValues from 2nd index.......please help
I can't tell you why the parameters are being passed out-of-sequence (I
would guess they're being shuffled through a HashMap somewhere) but it's
easy to deal with: simply have your setter grow the list as necessary to
accommodate the passed index. Something like this:
public void setFriend(int index, String name) {
while (friends.size() index) {
friends.add(null); // or or whatever
}
friends.put(index, name);
}
