This PR was merged into the 2.7 branch. Discussion ---------- Fixed the way flash messages are retrieved in the template In #7432 I changed the code of the templates to get the flash messages. I don't know why I did that ... because it's completely wrong 😵 In #7555 @lerox pointed this issue and I can confirm it: ![symfony_error](https://cloud.githubusercontent.com/assets/73419/23469257/6e423134-fea3-11e6-8d08-e56b01839404.png) So, let's revert it.
