[FLOW3-general] @scope session

[renst3 at e-rank.nl]

I've a question about the @session scope. If I understood it right a  
class with the scope session is contained during the whole  
usersession. So, this seems the right scope for a 'usersession' object  
;-)

But, how should I use it?

Whenever I use an object with the scope @session I get the error  
#1247211113: The session objects registry has not been injected  
correctly into the object manager.

To make sure the class itself does not contain any errors I created a  
test class:

<?php
declare(ENCODING = 'utf-8');
namespace F3\Package;

/**
  * @scope session
  */
class Test
{

}
?>

And I try to inject the object into a controller using:

/**
  * @var F3\Package\Test
  * @inject
  */
protected $test;

What am I doing wrong?

With kind regards,
Rens
