Using a data_class for the heck of it?

ProvinceSelector.php

<?php

namespace Comforce\Bundle\ImmoforceBundle\Model;

use Comforce\Bundle\GeoPostcodeBundle\Entity\Province;

class ProvinceSelector
{
    private $province;

    /**
     * @param  Province $province
     * @return $this
     */
    public function setProvince(Province $province)
    {
        $this->province = $province;

        return $this;
    }

    /**
     * @return Province|null
     */
    public function getProvince()
    {
        return $this->province;
    }
}

/*

Just to be able to do:

$selector = new ProvinceSelector();
$form = $this->createForm(new ProspectingProvinceType(), $selector);

if ($request->isMethod('post')) {
    $form->bind($request);

    if ($form->isValid()) {
        $province = $selector->getProvince()
    }
}

*/

/*

Alternatively, I could skip the class and do:

$form = $this->createForm(new ProspectingProvinceType());

if ($request->isMethod('post')) {
    $form->bind($request);

    if ($form->isValid()) {
        $data = $form->getData();
        $province = $data['province'];
    }
}

But I feel this is ugly...
