symfony - Symfony2 app.request.get('_route') is empty when throw new AccessDeniedException -

i'm working on implementing role based admin application. have custom voter , @ point i'm doing like:

if($role && voterinterface::access_granted !== $voteresult) {     throw new accessdeniedexception('unauthorized access!'); }

and result custom error403.html.twig template rendered. far good.

the error403 template extends main template in @ point i'm building menu using app.request.get('_route') generating links.

the problem app.request.get('_route') null.

xdebug-ing issue i've noticed somehow $request->attributes->parameters array not contain _route or _route_params keys.

any thoughts?

the problem symfony uses sub-request rendering error pages. doesn't need router , have not exatly same request object in master request.

github issue

same question on so

some theory

you can write own exception listener , modify behaviour in way.
