Hi Dhiren,
var obj = {prop1:10, prop2:20}
is equivalent to:
var obj = new Object();
obj.prop1 = 10;
obj.prop2 = 20;
And
var arr = [];
is equivalent to:
var arr = new Array();
So you can guess,
var dp = [
{Name:"Dhiren", Age:20}
];
is an array of object.
I guess, you can solve this problem by creating ValueObject in ActionScript
as well as in Java code:
##javacode##
package com.dhiren
public class DetailObject
{
public String Name;
public Integer Age;
public DetailObject(String N, String A)
{
Name = N
Age = A;
}
}
DetailObject[] detailObjectArr = new DetailObject[2];
detailObjectArr [0] = new DetailObject("Dhiren", 20);
detailObjectArr [1] = new DetailObject("Abdul", 24);
Send this to client to Flash...
##flexcode##
class com.dhiren.DetailObject
{
public var Name:String;
public var Age:Number;
public static var regClass =
Object.registerClass("com.dhiren.DetailObject", com.dhiren.DetailObject);
}
So now when flash would receive that array, class would automatically
mapped..
var detailValues = detailObjectArr;
dg.dataProvider = detailValues;

Abdul,
The array is being returned directly from Java code. I cannot use this
notation in a Java object: {Name:"Dhiren", Age:20}. I am not
explicitly creating the array in ActionScript, it is being evaluated
automatically.
BTW, what does this signify? I ran your example and see that Name:
shows up on the column header. Can you point me to some documentation
regarding this notation?
