Get itemlist from salesorder entity

[Serge]

Hello,

Is it correct i dont get the itemList property if i use this line of code?
So actually in general, the getEntityById doesnt return related entities?

 $salesOrder = $this->entityManager->getEntityById('SalesOrder', $salesOrderId);

Once I ask for itemList it returns me null

 $salesOrderItemList =  $salesOrder->get('itemList');

$items = $this->entityManager
    ->getRDBRepository('SalesOrderItem')
    ->where(['salesOrderId' => $salesOrderId])
    ->order('order')
    ->find();
