How to inject entity manager into filter class

[bartek75]

Hi, how do you get entity manager injected into filter class?
When i call validateIncomingData i got exception "Argument 1 passed to UserInputFilter::__construct() must implement interface Doctrine\ORM\EntityManagerInterface, none given"
NodefectFilter.php

<?php
namespace Project\Form;

use Zend\InputFilter\Factory as InputFactory;
use Zend\InputFilter\InputFilter;
use Doctrine\ORM\EntityManagerInterface;

class NodefectFilter extends InputFilter
{
    private $entityManager;

    public function __construct(EntityManagerInterface $entityManager)
    {   
        $this->entityManager = $entityManager;

        $this->add(array(
         ....
        ));

    }
}

in controller

$data  = $this->validateIncomingData(NodefectFilter::class);
