symfony - Symfony2 event subscriber does not call listeners -

i trying set simple event subscription based on example given here - http://symfony.com/doc/master/components/event_dispatcher/introduction.html.

here's event store:

namespace cookbook\inheritancebundle\event;  final class eventstore {     const event_sample = 'event.sample'; } 

here's event subscriber:

namespace cookbook\inheritancebundle\event;  use symfony\component\eventdispatcher\eventsubscriberinterface; use symfony\component\eventdispatcher\event;  class subscriber implements eventsubscriberinterface {     public static function getsubscribedevents()     {         var_dump('here');         return array(                 'event.sample' => array(                         array('samplemethod1', 10),                         array('samplemethod2', 5)                 ));     }      public function samplemethod1(event $event)     {         var_dump('method 1');     }      public function samplemethod2(event $event)     {         var_dump('method 2');     } } 

here's config in services.yml:

kernel.subscriber.subscriber:     class: cookbook\inheritancebundle\event\subscriber     tags:         - {name:kernel.event_subscriber} 

and here's how raise event:

use symfony\component\eventdispatcher\eventdispatcher; use cookbook\inheritancebundle\event\eventstore; $dispatcher = new eventdispatcher(); $dispatcher->dispatch(eventstore::event_sample); 

expected output:

string 'here' (length=4) string 'method 1' (length=8) string 'method 2' (length=8) 

actual output:

string 'here' (length=4) 

for reason, listener methods don't called. knows what's wrong code? thanks.

you might try inject configured eventdispatcher (@event_dispatcher) instead of instanciating new 1 (new eventdispatcher)

if create , add event-listener symfony still has no reference newly created eventdispatcher object , won't use it.

if inside controller extends containeraware :

use symfony\component\eventdispatcher\eventdispatcher; use cookbook\inheritancebundle\event\eventstore;  ...  $dispatcher = $this->getcontainer()->get('event_dispatcher'); $dispatcher->dispatch(eventstore::event_sample); 

i've adapted answer this question's answer though context of both questions different, answer still applies.
