Exception when extending ShopBillingData

Hi everyone,

I’m trying to extend the ShopBillingData. This is my class:



namespace MyProject\Model;

use Sylius\Component\Core\Model\ShopBillingData as BaseShopBillingData;
use Sylius\Component\Core\Model\ShopBillingDataInterface;

class ShopBillingData extends BaseShopBillingData implements ShopBillingDataInterface
    /** @var string */
    private $kvkNumber;

    /** @var string */
    private $bankAccountNumber;

    public function getKvkNumber(): ?string
        return $this->kvkNumber;

    public function setKvkNumber(string $kvkNumber): void
        $this->kvkNumber = $kvkNumber;

    public function getBankAccountNumber(): ?string
        return $this->bankAccountNumber;

    public function setBankAccountNumber(string $bankAccountNumber): void
        $this->bankAccountNumber = $bankAccountNumber;


I’ve placed doctrine mapping in ShopBillingData.orm.xml

<?xml version="1.0" encoding="UTF-8" ?>

<doctrine-mapping xmlns="http://doctrine-project.org/schemas/orm/doctrine-mapping"
                  xsi:schemaLocation="http://doctrine-project.org/schemas/orm/doctrine-mapping http://doctrine-project.org/schemas/orm/doctrine-mapping.xsd">

    <mapped-superclass name="MyProject\Model\ShopBillingData" table="my_project_shop_billing_data">
        <field name="kvkNumber" column="kvk_number" type="string" length="8" nullable="true" />
        <field name="bankAccountNumber" column="bank_account_number" type="string" length="34" nullable="true" />

I also created a Form Extension for the corresponding form. When I use the form with its new properties the data is stored in de database, but than i’m seeing the following exception on the channel edit page.

# An exception occurred while executing 'SELECT t1.company AS company_2, t1.tax_id AS tax_id_3, t1.country_code AS country_code_4, t1.street AS street_5, t1.city AS city_6, t1.postcode AS postcode_7, t1.id AS id_8, t1.kvk_number AS kvk_number_9, t1.bank_account_number AS bank_account_number_10 FROM my_project_shop_billing_data t1 WHERE t0.id = ?' with params [1]:

SQLSTATE[42S22]: Column not found: 1054 Unknown column 't0.id' in 'where clause'

I don’t understand why doctrine is using ‘t0’ as table alias in the where clause. Shouldn’t it be just ‘t1’? Does anyone has an idea why this happens?

Thanks in advance!

I asked this same question on the Sylius Slack. User diimpp pointed out that I was missing the following part in my _sylius.yaml:

                model: MyProject\Model\ShopBillingData
