use two plugins class together in one event manager in dispatcher

i need use two plugins class (Security class & Exceptions class) together in one event manager in dispatcher : Exceptions.php

namespace Multiple\Frontend\Plugins;

use Phalcon\Mvc\Dispatcher,
    Phalcon\Events\Event,
    Phalcon\Mvc\User\Plugin,
    Phalcon\Mvc\Dispatcher\Exception as DispatchException,
    Phalcon\Acl;

class Exceptions extends Plugin
{



    public function beforeException(Event $event, Dispatcher $dispatcher, $exception)
    {

        //Handle 404 exceptions
        if ($exception instanceof DispatchException) {
            $dispatcher->forward(array(
                'controller' => 'error',
                'action' => 'show404'
            ));
            return false;
        }

        //Handle other exceptions
        $dispatcher->forward(array(
            'controller' => 'error',
            'action' => 'show503'
        ));

        return false;
    }
}

Security.php >>>

namespace Multiple\Frontend\Plugins;

use Phalcon\Events\Event,
    Phalcon\Mvc\User\Plugin,
    Phalcon\Mvc\Dispatcher,
    Phalcon\Acl;

            $acl = new \Phalcon\Acl\Adapter\Memory();

            //Default action is deny access

dispatcher code >>>

$di->set('dispatcher', function() use ($di) {

how to manage more than one event together for EX: use event beforeDispatch with beforeException

What the events manager does is check for a method with the name of the event that it's triggering, so you can implement a class handling both events:

namespace Multiple\Frontend\Plugins;

use Phalcon\Mvc\Dispatcher,
    Phalcon\Events\Event,
    Phalcon\Mvc\User\Plugin,
    Phalcon\Mvc\Dispatcher\Exception as DispatchException;

class MyPlugin extends Plugin
{
    public function beforeDispatch(Event $event, Dispatcher $dispatcher)
    {
        //...
    }

    public function beforeException(Event $event, Dispatcher $dispatcher, $exception)
    {
        //...
    }
}

Register the plugin:

$di->set('dispatcher', function() use ($di) {

    //Create an EventsManager
    $eventsManager = new EventsManager();

    $plugin = new Multiple\Frontend\Plugins\MyPlugin($di);
    $eventsManager->attach('dispatch', $plugin);

    $dispatcher = new Phalcon\Mvc\Dispatcher();
    $dispatcher->setEventsManager($eventsManager);

    return $dispatcher;
});

so tanx i used but at this line that call event for triggering at the first run dispatch:beforeDispatch then dispatch:beforeException that not work !!! for example : http://localhost:8888/site/error : define on publicResources , out put after run ok http://localhost:8888/site/errorxxx : is not a controller so most refer to error controller and show404 index but refer to index and show : You don't have access to this module and refer to index
