session problem when called from other modules.

[eluser]bijufun[/eluser]
When i try to call

<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');

class Invoice extends CI_Controller {

function __construct()
{
parent::__construct();
$this->load->model('invoice_model');
modules::run('login/is_logged_in');
}
?>

When i validate user and assigned session. I get no error.
But once i redirect to the other page ( even same login controller), session is not more stored.

I get error in this line :
$is_logged_in = $this->session->userdata('is_logged_in');

A PHP Error was encountered

Severity: Notice

Message: Undefined property: Login::$session

Filename: controllers/login.php

I am using code igniter 2.0 with HMVC ..

Go back and read the Modular Extensions HMVC Bitbucket wiki. Take note of the difference between Modular Separation and Modular Extensions HMVC

thanx for the reply.. Actually I had set session['domain'].
When i remove the value, it seems working fine..
