Can I use Array/Collection of object?

[ili101]

I have an Entry, ApiResource. I also created another object and added it as a parameter and it's serialized nicely.

    #[ORM\Column(nullable: true, type: 'json_document')]
    private ?Choice $choices = null;

But I need more than one so I tried to make it an Array or Collection, for example:

{
  "id": 1,
  "name": "me",
  "choices": [
    {
      "label": "admin",
      "value": "admin",
      "default": false
    },
    {
      "label": "user",
      "value": "user",
      "default": false
    }
  ],
}

If I set it as an array it works but it becomes a generic array with sub-arrays and not Choice[]

    /**
     * @var Choice[]|null
     */
    #[ORM\Column(nullable: true, type: 'json_document')]
    private ?array $choices = null;

if I make it an ArrayCollection I get an error "Could not denormalize object of type "Doctrine\Common\Collections\Collection", no supporting normalizer found."

Can this be done using this module? If so, what is the recommended way to configure it?
Thank you

ok managed to get array working. if you don't have:

    public function addChoice(Choice $choice): void
    {
        $this->choices[] = $choice;
    }

the subobjects become arrays, if you add it you get objects.
