FuelPHP Forums

Hi guys,
I'm doing my first steps on the Framework FuelPHP. I installed and followed the following tutorials. I realized the standard agenda.
I wish I do now extend a class Core FuelPHP, allow me to define my own methods. I followed the example with the class Lang. Lang in the child class, I created a test method.

<?php
class Lang extends Fuel\Core\Lang {
 
 public static function test(){
  return 'test';
 }
 
}

I changed the View object of my note, to test the extension class:

<?php
public function action_view($id = null)
 {
  echo Lang::test();
  
  $this->data['note'] = Model_Note::find_by_pk($id);

 }

When I run my page I get the following error: ErrorException [ Error ]: Call to undefined method Fuel\Core\Lang::test()
I do not understand my error can you help me?
Thank you
