Use statement Template

[Semantical Error] The annotation "@Template" in method Acme\BasicCmsBundle\Controller\DefaultController::pageAction() was never imported. Did you maybe forget to add a "use" statement for this annotation?
Yes we did :-)

Also, running http://localhost:8000/page/home for the first time didn't work. I got an error about routes and the /Document/Page
The error was on line 6 on the page.html.twig file, without {{ path( post) }} it worked. Very strange, suddenly it worked. Some caching stuff?
(sorry, I don't have the exact error message, I can't reproduce it anymore)
Aah ok, I wasn't aware, sorry
