Hi there Phalcon community,

My form->isValid() method gives me a fatal error

[Wed May 07 14:39:58 2014] [warn] [client 94.210.222.87] mod_fcgid: stderr: PHP Fatal error: Maximum recursion depth exceeded in /var/www/vhosts/mydomain.com/httpdocs/app/controllers/DebiteurenController.php on line 21, referer: http://mydomain.com/debiteuren/formulier 

This the action

public function formulierAction($debiteurNummer = null) {

        $this->view->formulierModus = (!is_null($debiteurNummer)) ? "wijzigen" : "aanmaken" ;

        if(!is_null($debiteurNummer)) {
            $form = new DebiteurFormulier(Debiteuren::findFirstBydebiteurnummer($debiteurNummer));
        } else {
            $form = new DebiteurFormulier();
        }

        if($this->request->isPost() && $form->isValid($this->request->getPost())) {

            if(!is_null($debiteurNummer)) {
                $dbModel = Debiteuren::findFirstBydebiteurnummer($debiteurNummer);
            }else {
                $dbModel = new Debiteuren();
            }

            $form->bind($this->request->getPost(), $dbModel);

            if($dbModel->save()) {
                $this->response->redirect('debiteuren');
            }

        }

        $this->view->form = $form;

    }

And this is my form class

class DebiteurFormulier extends Form {

    public function initialize($debiteurData = NULL, $options = Array()) {

        $bedrijfsnaam = new Text('bedrijfsnaam');
        $bedrijfsnaam->addValidator(new PresenceOf( array('message' => 'Dit veld is verplicht.')));
        $this->add($bedrijfsnaam);

        $adres = new Text('adres');
        $adres->addValidator(new PresenceOf( array('message' => 'Dit veld is verplicht.')));
        $this->add($adres);

        $postcode = new Text('postcode');
        $postcode->addValidator(new PresenceOf( array('message' => 'Dit veld is verplicht.')));
        $this->add($postcode);

        $woonplaats = new Text('woonplaats');
        $woonplaats->addValidator(new PresenceOf( array('message' => 'Dit veld is verplicht.')));
        $this->add($woonplaats);

    }
}

The strange thing is that it has worked with other projects, but they were on a lower version then this installation (1.3.1). The form builder seems to be working fine, since it does pass data in-to my form but when it comes down to the validation part the application crashes.

Help is much appreciated!
