User class not found

How and to which class are you passing the utilities or user object?

Did a quick test with two libraries. One I called Utilities and the second one Test.
I then did this:

PHP Code:

$this->load->library('Utilities');
$this->load->library('Test', array($this->utilities)); 


Got 0 errors with this. So Utilities is not a reserved name within CI nor does CI change it in anyway that I chould see.

Thanks,now I see that the problem is in the instanciation of the other class (Test in your example), which I did not perform correctly.
But now after the commands

$this->load->library('Test', array($this->utilities)); //here no error occurs
--
$vars = get_object_vars($this->Test);
var_dump($vars);

I get the error
Message: Undefined property: Test::$Test
and
Message: get_object_vars() expects parameter 1 to be object, null given
