Passing product properties to cart D7 how to solve wiping problem?

Question

1C-Bitrix

Hello!
There is a problem with the new D7 kernel.
I have a property details in the product card.

The transfer of product properties to the basket is carried out in the following way:

$props = array();
$basketPropRes = Sale\Internals\BasketPropertyTable::getList(array(
  'filter' => array(
    "BASKET_ID" => $arBasket["ID"],
  ),
));
while ($property = $basketPropRes->fetch()) {
  unset($property["BASKET_ID"]);
  $props[] = $property;
}
$item = $basket->createItem('catalog', $_REQUEST["prod"]);
$basketPropertyCollection = $item->getPropertyCollection();
$basketPropertyCollection->setProperty($props);
$basketPropertyCollection->save();

When the $props array is printed out, the result is:

Array
(
    [0] => Array
        (
            [ID] => 279563
            [NAME] => Склад
            [VALUE] => 20
            [CODE] => STORE
            [SORT] => 100
        )

    [1] => Array
        (
            [ID] => 279564
            [NAME] => Название склада
            [VALUE] => Склад СПб Центральный
            [CODE] => STORE_NAME
            [SORT] => 100
        )

    [2] => Array
        (
            [ID] => 279565
            [NAME] => Артикул
            [VALUE] => 327320097
            [CODE] => CML2_ARTICLE
            [SORT] => 100
        )

    [3] => Array
        (
            [ID] => 279566
            [NAME] => Реквизиты
            [VALUE] => Gerep
            [CODE] => CML2_TRAITS
            [SORT] => 100
        )

    [4] => Array
        (
            [ID] => 279567
            [NAME] => Реквизиты
            [VALUE] => a29c8f2f-b5b8-11e4-8e7b-00155dc0ba09
            [CODE] => CML2_TRAITS
            [SORT] => 100
        )

    [5] => Array
        (
            [ID] => 279568
            [NAME] => Реквизиты
            [VALUE] => Товар (пр. ТМЦ)
            [CODE] => CML2_TRAITS
            [SORT] => 100
        )

    [6] => Array
        (
            [ID] => 279569
            [NAME] => Реквизиты
            [VALUE] => Товар
            [CODE] => CML2_TRAITS
            [SORT] => 100
        )

)

But when I output the saved properties

dump($basketPropertyCollection->getPropertyValues());

I get only four properties instead of six, and the props property is overwritten:

Array
(
    [STORE] => Array
        (
            [CODE] => STORE
            [ID] => 295667
            [VALUE] => 20
            [SORT] => 100
            [NAME] => Склад
        )

    [STORE_NAME] => Array
        (
            [CODE] => STORE_NAME
            [ID] => 295668
            [VALUE] => Склад СПб Центральный
            [SORT] => 100
            [NAME] => Название склада
        )

    [CML2_ARTICLE] => Array
        (
            [CODE] => CML2_ARTICLE
            [ID] => 295669
            [VALUE] => 327320097
            [SORT] => 100
            [NAME] => Артикул
        )

    [CML2_TRAITS] => Array
        (
            [CODE] => CML2_TRAITS
            [ID] => 295673
            [VALUE] => Товар
            [SORT] => 100
            [NAME] => Реквизиты
        )

)

I don’t understand what to do, in the old method an array was simply passed and there were no problems, now something is going wrong. Can someone tell me what the problem is or how to do it right?

Answer 1

note [CODE] => CML2_TRAITS all 3 attributes are the same.
