Embeddables doesn´t support relationships

[Ivorius]

It can not be used relationship in embeddables because throw exception Nextras\Orm\NullValueException

Property ...\Order::$country is not nullable

/**
 * @property-read string|NULL $street
 * @property-read string|NULL $city
 * @property-read string|NULL $postCode
 * @property Country $country {default CZ} {m:1 Country, oneSided=true}
 */
class Address extends \Nextras\Orm\Entity\Embeddable\Embeddable
{
	public function __construct(string $street, string $city, string $postCode, Country $country)
	{
		parent::__construct([
			'street' => $street,
			'city' => $city,
			'postCode' => $postCode,
			'country' => $country,
		]);
	}
}

Mapping

		$conventions->setMapping('address->street', 'street');
		$conventions->setMapping('address->city', 'town');
		$conventions->setMapping('address->postCode', 'postcode');
		$conventions->setMapping('address->country', 'country_code');
