symfony easyadmin form field type entity with filter list

I use symfony 3.4 and easycorp/easyadmin-bundle 1.17

This is my class "Quotation", the "artisan" field is an "under registration" of the "Person" entity (person.type = 1) :

class Quotation
{
/** others fields... */

/**
 *  1 => 'artisan', 2 => 'customer'
 */
private $type;

/**
 * @ORM\ManyToOne(targetEntity="Person", inversedBy="artisanQuotations", cascade= { "persist" })
 * @ORM\JoinColumn(name="artisan_id", referencedColumnName="id")
 */
private $artisan;

    /** getters and setters ... */

I have a problem with a form field using a custom field type

form:
    fields:
        ...
        - { property: 'artisan', label: '', type: 'AppBundle\Form\Field\ArtisanType' }

I created this form field type to be able to filter the list thanks to the query_builder :

public function buildForm(FormBuilderInterface $builder, array $options)
{
    $builder->add('artisan', EntityType::class, array(
        'class' => 'AppBundle:Person',
        'label' => false,
        'query_builder' => function(EntityRepository $er) {
            return $er->createQueryBuilder('person')
                ->where('person.type = 1');
        },
        'attr' => array('data-widget' => 'select2'),
        'multiple' => false,
        'expanded'=> false
    ));
}

my form is displayed perfectly well but when i submit this form i have an error :

Expected argument of type "AppBundle\Entity\Person", "array" given

Thank you in advance for your help

Instead of using the buildForm method you should use configureOptions here. That way your form is not extended by another subform which results in the array.

use Doctrine\ORM\EntityRepository;

use Symfony\Component\Form\AbstractType;
use Symfony\Bridge\Doctrine\Form\Type\EntityType;
use Symfony\Component\OptionsResolver\OptionsResolver;

class ArtisanType extends AbstractType
{

    /**
    * @param \Symfony\Component\OptionsResolver\OptionsResolver $resolver
    */
    public function configureOptions(OptionsResolver $resolver)
    {
        $resolver->setDefaults([
            'class' => 'AppBundle:Person',
            'label' => false,
            'query_builder' => function(EntityRepository $er) {
                return $er->createQueryBuilder('person')
                    ->where('person.type = 1');
            },
            'attr' => array('data-widget' => 'select2'),
            'multiple' => false,
            'expanded'=> false,
        ]);
    }

    /**
    * @return string|null
    */
    public function getParent()
    {
        return EntityType::class;
    }
}
