Flex pass data or objects from one mxml to another

The best way to pass the objects or array across the mxml's is to use Shared Objects.

Declaring a Shared Object :

public var studentSO:SharedObject = SharedObject.getLocal("student","/");

Set values to Shared Objects :

studentSO.data.id = 101;
studentSO.arr = new Array([1,2,3]);

studentSO.flush();


Get values from Shared Objects :

private var i:int = studentSO.data.id;
private var arr:Array = studentSO.arr;
