I have a small problem. I have already overridden the templates in app/Resources/TwigBundle/views/Exception/ and have error, error404 and error500.html.twig respectively. I have deleted the cache and upon going on a undefined page I get:
Fatal error: Uncaught exception 'Symfony\Component\Routing\Exception\ResourceNotFoundException' in E:\svn\medapp\app\cache\prod\appProdUrlMatcher.php:4044 Stack trace: #0 E:\svn\medapp\app\cache\prod\classes.php(1433): appProdUrlMatcher->match('/asdasd') #1 E:\svn\medapp\app\cache\prod\classes.php(19616): Symfony\Component\Routing\Matcher\UrlMatcher->matchRequest(Object(Symfony\Component\HttpFoundation\Request)) #2 E:\svn\medapp\app\cache\prod\classes.php(2583): JMS\I18nRoutingBundle\Router\I18nRouter->matchRequest(Object(Symfony\Component\HttpFoundation\Request)) #3 [internal function]: Symfony\Component\HttpKernel\EventListener\RouterListener->onKernelRequest(Object(Symfony\Component\HttpKernel\Event\GetResponseEvent), 'kernel.request', Object(Symfony\Component\EventDispatcher\ContainerAwareEventDispatcher)) #4 E:\svn\medapp\app\cache\prod\classes.php(2352): call_user_func(Array, Object(Symfony\Component\HttpKernel\Event\GetResponseEvent), 'kernel.request', Object(Symfony\Component\EventDispatcher\ContainerAwareEventDis in E:\svn\medapp\app\cache\prod\classes.php on line 5334 503 Service Unavailable

If I delete or rename the TwigBundle templates and then delete the cache, I get the standard Symfony error page:
Oops! An Error Occurred
The server returned a "404 Not Found".
Something is broken. Please let us know what you were doing when this error occurred. We will fix it as soon as possible. Sorry for any inconvenience caused.
What am I missing?
I found the error, sorry for the bother.
The problem was the error templates were calling parent() for the templates they are extending
{% extends 'MedAppBundle:Default:base.html.twig' %}
{% block body %}
{{ parent() }}
<div class="container-fluid" >
<div class="row" >
<div class="col-xs-12 col-sm-12 col-md-12 col-lg-12 error-content" >
<h1 class="error-title">404</h1>
<h2 class="error-header2">Resource Not Found
</h2>
<p>The resource requested could not be found on this server!</p>
</div>
</div>
</div>
{% endblock body %}
And in the parent template I was asking for the token storage.
Something good to learn for the future.
