Trying to cast $address_val to Address object:

class AlbumData extends Data
{
    public string $title;
    #[WithCast(AddressCast::class)]
    public ?Address $address_val;
    
}

try {
    AlbumData::validateAndCreate([
        'title' => 'Never Gonna Give You Up',
        'address_val' => 'Never Gonna Give You Up',
    ]);
} catch (ValidationException  $exception) {
    dump($exception->validator->errors()->all());
    dd($exception->getMessage());
}

Error message:

> "The address_val field must be an array."

class Address extends Data
{
    public function __construct(
        public ?string $text,
    ) {}
}

class AddressCast implements Cast
{
    public function cast(DataProperty $property, mixed $value, array $properties, CreationContext $context): Address
    {
        return new Address($value);
    }
}

What am I doing wrong?

Notes:

1. If you use the from method instead of validateAndCreate, then there is no error and everything works properly.
2. If Address NOT extends Data, aslo works properly.

class AlbumData extends Data
{
    public string $title;
    #[WithCast(AddressCast::class)]
    public ?Address $address_val;
    
}

try {
    AlbumData::validateAndCreate([
        'title' => 'Never Gonna Give You Up',
        'address_val' => 'Never Gonna Give You Up', <-- HERE
    ]);
} catch (ValidationException  $exception) {
    dump($exception->validator->errors()->all());
    dd($exception->getMessage());
}

Data class from() method doesn't perform validation and validateAndCreate() expects array like this:

AlbumData::validateAndCreate([
        'title' => 'Never Gonna Give You Up',
        'address_val' => ['text' => Never Gonna Give You Up'], <-- FIX
    ]);

Other depends on your business logic, wether to keep your class extended or not
