php - Why is symfony2 not calling my event listeners? -

i have program 2 bundles. 1 of them (commonbundle) dispatches event "common.add_channel", while service on other 1 (fetcherbundle) supposed listening it. on profiler, can see event common.add_channel in "not called listeners" section. don't why symfony not registering listener.

this action, inside commonbundle\controller\channelcontroller::createaction:

$dispatcher = new eventdispatcher(); $event = new addchannelevent($entity);         $dispatcher->dispatch("common.add_channel", $event); 

this addchannelevent:

<?php  namespace naroga\reader\commonbundle\event;  use symfony\component\eventdispatcher\event; use naroga\reader\commonbundle\entity\channel;  class addchannelevent extends event {      protected $_channel;      public function __construct(channel $channel) {         $this->_channel = $channel;     }      public function getchannel() {         return $this->_channel;     }  } 

this supposed listener (fetcherservice.php):

<?php  namespace naroga\reader\fetcherbundle\service;  class fetcherservice {      public function onaddchannel(addchannelevent $event) {         die("it's here!");           } } 

and here's register listener (services.yml):

kernel.listener.add_channel:     class: naroga\reader\fetcherbundle\service\fetcherservice     tags:         - { name: kernel.event_listener, event: common.add_channel, method: onaddchannel } 

what doing wrong? why isn't symfony calling event listener when dispatch common.add_channel?

the new event dispatcher doesn't know listeners set on dispatcher.

in controller, need access event_dispatcher service. compiler pass of framework bundle attached listeners dispatcher. service, use controller#get() shortcut:

// ... use symfony\bundle\frameworkbundle\controller\controller;  class channelcontroller extends controller {     public function createaction()     {         $dispatcher = $this->get('event_dispatcher');         // ...     } }
