CONTROLLER

This bundle contains an AbstractController to provide a backward compatibility with Symfony.

The following methods are available:

• dispatchEvent($eventName, BaseEvent $event)
• getEventDispatcher()
• getFormHelper()
• getLogger()
• getRouter()
• getSession()
• getTranslator()
• notify($eventName, NotificationInterface $notification)
• toast($eventName, ToastInterface $toast)

dispatchEvent($eventName, BaseEvent $event)

This method provides the same prototype regardless of Symfony version.

Into a controller with Symfony < 4.3:

    $eventDispatcher = $this->get("event_dispatcher");
    $eventDispatcher->dispatch($eventName, $event);

Into a controller with Symfony 4.3 and more:

    $eventDispatcher = $this->get("event_dispatcher");
    $eventDispatcher->dispatch($event, $eventName);

IMPORTANT NOTICE: The $eventName and $event are permuted.

With a controller inherit from our AbstractController, the usage of dispatchEvent($eventName, $event) works always with the following code:

    $this->dispatchEvent($eventName, $event);
