As you know there is not variables like session in flex.But i have created a class call session that can perform the task of session in our day to day programming life.Class have two basic methods setAttribute and getAttribute.we can keep any type value as key and value.
What is inside happening? I used singleton design pattern,generic and dictionary for the work.
You can Use the following class as a session in flex.

[Bindable]
private var session:Session = Session.getInstance();

How to insert data to session
session.setAttribute('username','sanka')

How to retrive data from session
var userName:String=session.getAttribute('username');
