Answer 1

Seems that doctrine-bridge form component is not configured.
Add class

namespace Your\Namespace;

use Doctrine\Common\Persistence\AbstractManagerRegistry;
use Silex\Application;

class ManagerRegistry extends AbstractManagerRegistry
{
    protected $container;

    protected function getService($name)
    {
        return $this->container[$name];
    }

    protected function resetService($name)
    {
        unset($this->container[$name]);
    }

    public function getAliasNamespace($alias)
    {
        throw new \BadMethodCallException('Namespace aliases not supported.');
    }

    public function setContainer(Application $container)
    {
        $this->container = $container;
    }
}

and configure doctrine-bridge form component

$application->register(new Silex\Provider\FormServiceProvider(), []);

$application->extend('form.extensions', function($extensions, $application) {
    if (isset($application['form.doctrine.bridge.included'])) return $extensions;
    $application['form.doctrine.bridge.included'] = 1;

    $mr = new Your\Namespace\ManagerRegistry(
        null, array(), array('em'), null, null, '\\Doctrine\\ORM\\Proxy\\Proxy'
    );
    $mr->setContainer($application);
    $extensions[] = new \Symfony\Bridge\Doctrine\Form\DoctrineOrmExtension($mr);

    return $extensions;
});

array('em') - em is key for entity manager in $application

Answer 2

For others that may find this: If you want to use the EntityType and you're not using a framework at all, you need to add the DoctrineOrmExtension to your FormFactoryBuilder like so:

$managerRegistry = new myManagerRegistry(
    'myManager',
    array('connection'),
    array('em'),
    'connection',
    'em',
    \Doctrine\ORM\Proxy\Proxy::class
);

// Setup your Manager Registry or whatever...

$doctrineOrmExtension = new DoctrineOrmExtension($managerRegistry);
$builder->addExtension($doctrineOrmExtension);

When you use EntityType, myManagerRegistry#getService($name) will be called. $name is the name of the service it needs ('em' or 'connection') and it needs to return the Doctrine entity manager or the Doctrine database connection, respectively.

Answer 3

In your controller, try to call the service like that:

$em = $this->get('doctrine.orm.entity_manager');

Hope it will help you.

Edit:

Sorry, I thought you was on Symfony... I have too quickly read...
