Cannot load resource when using routing type be_simple_i18n

[SimpleSimplicity]

Steps to reproduce:

Create a new project with the welcome page.

Install and configure the bundle per instructions.

Change the welcome page type to be_simple_i18n.

Outcome:

  Cannot load resource "@AppBundle/Controller/IndexController.php". Make sure the "AppBundle" 
  bundle is correctly registered and loaded in the application kernel class. If the bundle is registered, 
  make sure the bundle path "@AppBundle/Controller/IndexController.php" is not empty. 

Any ideas or what could be causing that?
I've tried on both Symfony 3.0.2 and 2.6

try inserting in AppKernel, the following instruction

new BeSimple\I18nRoutingBundle\BeSimpleI18nRoutingBundle(),

before

new Tac\AppBundle\TacAppBundle(),
