custom library with parameters : problem

Thanks, but it's not working too because i note that :
- if you load library in the view page, there is error
- if you load library in the controller and then use it in the view, that's working !!

PHP Code:

// controller file
public function method_controller() {
     $args = array('green', 'blue');
     $this->load->library('example', $args);
     $this->load->view('my_view');
} 


PHP Code:

// view file : my_view.php
     echo $this->example->get(0); // works 


Perhaps, it's the only way to do that.
