Checkbox validation on ZF2

I have a problem with the ZF2 Form validation. The isValid() return is false always I use a checkbox in my form. If I change that element to a text element, it works normally. Below is my code. Can anyone help me?

Thank you!

Entity/Marca.php

namespace Application\Entity;

class Marca
{
    /**
     * @var string
     */
    protected $select;

    /**
     * @var string
     */
    protected $descr;

    function getSelect()
    {
        return $this->select;
    }

    function getDescr()
    {
        return $this->descr;
    }

    function setSelect($select)
    {
        $this->select = $select;
        return $this;
    }

    function setDescr($descr)
    {
        $this->descr = $descr;
        return $this;
    }
