Oxidshop - Override changebasket function in BasketComponent

Question

I am customising Oxidshop for one of my clients. I want to customise the "changebasket" function in BasketComponent file to add more validations to it. For this purpose I have also created a custom module. I am trying to extend the class using metadata file.

'extend' => array(
        'oxcmp_basket' => \MyVendor\Basket\Application\Components\BasketComponent::class,
    ),

The BasketComponent file has following code,

<?php
namespace MyVendor\Basket\Application\Components;

/**
 * Class LinslinSliderMain.
*/
class BasketComponent extends BasketComponent_parent
{
 /**
 * @param null $sProductId
 * @param null $dAmount
 * @param null $aSel
 * @param null $aPersParam
 * @param bool $blOverride
 */
 public function changebasket($sProductId = null, $dAmount = null, $aSel = null, $aPersParam = null, $blOverride = true)
 {
    echo 'call success';exit;
    parent::changebasket($sProductId, $dAmount, $aSel, $aPersParam, $blOverride);
 }
}

The gets activated. However, when I refresh any page in frontend, it gets deactivated automatically. I don't know, what's wrong with the code.

EDIT: I am getting this error in oxideshop.log file

Module class MyVendor\Basket\Application\Components\BauerBasketComponent not found. Module ID basket disabled.

depending on your OXID eShop version it might be a different line, but the error message you are stating originates from OxidEsales\EshopCommunity\Core\Module\ModuleChainsGenerator::onModuleExtensionCreationError.

When activating your module, the system tries to generate the class chain with your BasketComponent class in it. As your class is a namespaced class, OXID tries to check if it can find the class via the composer autoload file, if not, the shop throws this exception.

So I assume the module is not installed via composer, at least the namespace seems unknown to composer. You can check in the module documentation on how this should be achieved

Hope I could help
