In the development environment, Symfony catches all the exceptions and displays a special exception page with lots of debug information to help you quickly discover the root problem: Since these pages contain a lot of sensitive internal information, Symfony won't display them in the production environment. Instead, it'll show a simple and generic error page: Error pages for the production environment can be customized in different ways depending on your needs: If you just want to change the contents and styles of the error pages to match the rest of your application, override the default error templates; If you also want to tweak the logic used by Symfony to generate error pages, override the default exception controller; If you need total control of exception handling to

The problem is with the overrided Twig 404 template. It is overrided in a default way by creating an error404.html.twig under the /app/Resources/TwigBundle/views directory. The template itself does not contain any irregular or complex logic: just a http://stackoverflow.com/questions/27276778/symfony-2-and-twig-custom-error-page layout with some translated text (|trans) and a menu with several links. The problem is, that I can't get app.user object (returned as NULL) or current app.request.locale (always returned as default locale) inside this template. I have even tried to override the twig exception controller and dump a current locale (Request::getLocale()) or get user - the results are the same - default locale and NULL for user. Then I decided to dig deeper and found a dozens of listeners (locale listeners, exception liteners, ...) and tried to debug/fix/test there, but I didn't proceed any further. By the way, I have overrided the 500 error page too, and everything is fine there. Well I guess that when 500 error (exception) is thrown, the symfony has already set up user/locale/etc, because it already has got to the target (controller/action) and other listeners been already executed. But 404 error (NotFoundHttpException) is being thrown BEFORE Symfony targets the action... Some words about project: symfony 2.4.8, doctrine, Gedmo extensions/stof bundle, JMS i18n routing bundle.

for them. You will also learn how to efficiently develop and preview custom error pages. Updated on March 19, 2014Great news! The Symfony2 cookbook page https://www.webfactory.de/blog/symfony2-exception-handling-and-custom-error-pages-explained has been updated and now mentions the bundle described here. We've updated this article accordingly.There's a recipe over in the Symfony2 cookbook how to change the default error pages displayed https://www.youtube.com/watch?v=L9m3hgO70-M when an uncaught exception occurs in your Symfony2 application.What it does not tell you is how to efficiently develop and preview such custom error pages. But before we error page come to that, let me explain what happens behind the scenes when an exception occurs.Control flow during exception handling0. All requests for your Symfony2 application go through the HttpKernel's handle() method. Whenever an exception occurs that is not contained within the application but reaches the HttpKernel level, …1. ... the kernel dispatches a KernelEvents::EXCEPTION type event to notify interested custom 500 error listeners of the situation. Listeners can either change the exception or provide a Response object. If a response is provided, it basically gets returned from the initial handle() method. If not, the exception is thrown out of the kernel.That's it from the kernel's perspective already. So let's have a look at the event listeners that do the heavy lifting.2. The HttpKernel component also contains the ExceptionListener class that does two things: First, it logs the exception using the LoggerInterface. Second, it dispatches a sub-request back to our distressed kernel. This sub-request is set up to run a controller of a given (configurable) name and receives the exception (actually, a FlattenException instance of it) as a controller parameter. See the "kernel.exception in the Symfony Framework" box over here for details.3. The actual setup as an event subscriber happens in the TwigBundle where a service twig.exception_listener is defined. This service uses the ExeptionListener class, tweakable through the %twig.exception_listener.class% parameter. Remember that this listener needs the name of a controller to run? It is given by yet another parameter:4. The %tw
