I use only a few Symfony components, so maybe that is why it does not work as expected; when updating web-profiler-bundle from v4.0.5 to v4.0.7 all my web-tests started to fail because the application cannot generate a route due to a missing parameter or something (should flex not have auto-updated the configuration or is this route not part of the default config of the profiler "bundle"?).

Symfony\Component\Routing\Exception\RouteNotFoundException: 
Unable to generate a URL for the named route "_profiler_open_file" as such route does not exist.

Did I screw up the whole way flex is supposed to be used and such? :p
