This is also the case in Symfony2.0 so it needs to be merged into the 2.0 branch |
|
I opened a new PR against 2.0 branch. |
|
It was better to let it as it was. Ryan can merge this to the 2.0 branch, I had written my comment to let Ryan know that this isn't a specific 2.1 feature. But thank you for your PR (and time)! |

i think it easier to merge 2.0 branch into master. |

see https://github.com/symfony/symfony/blob/master/src/Symfony/Component/EventDispatcher/EventDispatcher.php#L164
the second argument of
$dispatcher->addListenermust be callabled. so I think it is a typo.
