Why don't flash drives work after redirect in symfony 2?

Question

symfony

like this doesn't work:

$this->addFlash(
                        'notice',
                        'Файл успешно заружен. Количество добавленных организаций: ' . 1
                    );
                    return $this->redirect($this->generateUrl($request->get('_route'), $request->query->all()));

and this is how it works

$this->addFlash(
                        'notice',
                        'Файл успешно заружен. Количество добавленных организаций: ' . 1
                    );
                    exit;

Answer 1

Doesn't the browser give you a circular redirect error?
If you only have these two lines in your controller, then you do the following:

function foo() {
    return foo();
}

If this is not the case, then you will be redirected 2 times.
In app/config/config_dev.yml add redirect debug.
