Codeigniter User Auth Library

[eluser]Unknown[/eluser]
Hi,

This looks interested, but when calling either

$this->user->get_name();
$this->user->get_id();

It complains with

Message: Trying to get property of non-object
Filename: libraries/User.php
Line Number: 170

When profiling it, the session data shows;

user_data
login admin
pw admin
logged 1
