RE: Error - [Ljava.lang.String;@d23.

I hope that I am not too far out of touch with what you are attempting to
accomplish, but I think I understand. There are a couple of things that you
will have to do to get this working properly. In essence, what you want to
do is use an indexed property. First, modify your Java bean as such:

  private String[] firstName;

  /*
    // do the following in the constructor
    // DEFAULT_SIZE should be whatever the maximum number of firstNames are
allowed
    firstName = new String[DEFAULT_SIZE];
  */

  public String[] getFirstName(){
    return FirstName;
  }

  public void setFirstName(String[] newName){
    firstName = newName;
  }

  public String getFirstName(int i){
    return firstName[i];
  }

  public void setFirstName(int i, String newName){
    firstName[i] = newName;
  }

You will have to initialize the array to some default size in the
constructor of the Java bean, otherwise the code below may throw a null
pointer exception. If you need the size of the array to be dynamically
resizable, perhaps you could use an ArrayList instead and have your Java
bean methods encapsulate this fact. 

Then, in the JSP, you will have to iterate over every element in that array
and use a tag of the following form:

<html-el:text property="firstName[${i}]"  />

You will also have to modify any validation on this property for this form.
See http://marc.theaimsgroup.com/?l=struts-user&m=104773695010730&w=2 for
details. I do not have much experience with this aspect of indexed
properties, but it seems like support for this in the validator is limited
to statically declaring validation on a specific named element such as
firstName[1] or firstName[88].

This should also solve the repopulation problems that you were experiencing.
I hope that this helps.

I do have multiple elements of the same name. I started to work with one
element and then I got this error. 

So do I have to add any thing more to the tag?

Thanks

Thats the default stringified version of your array. It looks like from
the
tag your using you just want to print a simple string, why are you
trying to
pass an array as the property?

Hi

I get the following error when the jsp page is displayed after the
validation fails (Validation errros are all working fine)

[Ljava.lang.String;@d23.

This happens when I am passing values to a String Array. eg: .jsp I have

<html:text property="firstName"  />

These are my set and get methods in my ActionForm

private String [] FirstName=null;

public String[] getfirstName(){
    return FirstName;
  }

  public void setfirstName(String[] newName){
    FirstName = newName;
  }

It works fine when I use String but returns jusn when using String
array.
The values are being set correctly when I ran in debug mode.

Is this a bug??

Thanks
