Multiple ChoiceType, array expected

Question

I am trying to make a multiple-select ChoiceType in my Symfony form. However, I am getting the following error:

Unable to transform value for property path "[organisations]": Expected an array.

Note: If I change the name of the component from organisations to anything else, it's rendering the form correctly.

As far as I can see, organisations is an array:

/**
 * @var Organisation[]
 * @ORM\ManyToMany(targetEntity="Booking\Entity\Organisation", inversedBy="users")
 * @ORM\JoinTable(name="users_organisations")
 */
protected $organisations;

Here's the form:

$organisations = $doctrine->getRepository('Booking\Entity\Organisation')->findAll();

$builder
    ->add('organisations', ChoiceType::class, array(
        'choices' => $organisations,
        'choice_label' => function($organisation, $key, $index) {
            return $organisation->getName();
        },
        'multiple' => true
    ))

What am I doing wrong?

Can you post the entire exception thrown? This is probably not because of the model but rather what data you submit to the form field. — martin

@Martin I just added some extra details to the question. If I change organisations to anything else, the form is rendered correctly — Patrick Reck

Well, can you post the entire exception trace stack and you form definition? — martin

Why won't you use EntityType instead? It would be simpler. — Jakub Matczak

Use EntityType instead.

$builder
    ->add('organisations', EntityType::class, array(
        'choices' => $organisations,
        'choice_label' => function($organisation, $key, $index) {
            return $organisation->getName();
        },
        'multiple' => true
    ))
