ZF2 How to access event manager in controller's constructor -

how access event manager in controller constructor ? when call event manager in constructor , error appears :

zend\servicemanager\servicemanager::get unable fetch or create instance event

you don't have access service manager @ point, it's injected once object has been instantiated.

you move code triggered ondispatch() rather in contructor:

/**  * execute request  *  * @param  mvcevent $e  * @return mixed  * @throws exception\domainexception  */ public function ondispatch(mvcevent $e) {     // here     // or use events system attach ondispatch event     // rather putting code directly controller,      // better option      return parent::ondispatch($e); } 

i use events attach ever need, rather using controller

module.php

/**  * initialize  *   * @param \mis\modulemanager   */ public function init(modulemanager $manager) {     $events = $manager->geteventmanager();     $sharedevents = $events->getsharedmanager();     $sharedevents->attach(__namespace__, 'dispatch', function($e) {         /* @var $e \zend\mvc\mvcevent */         // fired when actioncontroller under namespace dispatched.         $controller = $e->gettarget();         $routematch = $e->getroutematch();         /* @var $routematch \zend\mvc\router\routematch */         $routename = $routematch->getmatchedroutename();          // attach method here need      }, 100); }
