getPositionAssociatedData example

        $position = $this->getManager()->getRepository(OrderDetail::class)->find($id);
        if (!$position instanceof OrderDetail) {
            $position = new OrderDetail();
            $attribute = new OrderDetailAttribute();
            $position->setAttribute($attribute);
            $this->getManager()->persist($position);
        }

        $data = $this->Request()->getParams();
        $data['number'] = $order->getNumber();

        $data = $this->getPositionAssociatedData($data, $order);

        $position->fromArray($data);
        $position->setOrder($order);

        $this->getManager()->flush();

        // If the passed data is a new position, the flush function will add the new id to the position model         $data['id'] = $position->getId();

        // The position model will refresh the product stock, so the product stock         // will be assigned to the view to refresh the grid or form panel.
