This is my observer:

public function changeStatus(Varien_Event_Observer $observer)
    {
        $order = $observer->getEvent()->getOrder();
        $getOrder =  Mage::getModel('sales/order')->load($order->getId());
        $OldOrder = Mage::getModel('sales/order')->load($getOrder->getData('relation_parent_id'));
        $OldOrder->setState('mystatushere', true)->save();

    }

I used this event: sales_order_save_before or sales_order_save_after. I know the code is not optimized, so please don't blame me :D . What I want to achieve is to change the parent order status. I edit an order, make some modification and save it. A new order is created with increment-id-1 and when it this one is save I want to change the status of its parent order.

But I 'm receiving this: Fatal error: Uncaught Error: Call to a member function getMethodInstance() on boolean in app/code/core/Mage/Payment/Model/Observer.php:46. Any idea why ? thx

You are getting this error because $order = $observer->getEvent()->getOrder(); is not working.

UPDATE:

$order = $observer->getEvent()->getOrder();
if(!$order->getId()){
    $order->setState(Mage_Sales_Model_Order::STATE_NEW, true);
}

OR :

$order = $observer->getEvent()->getOrder();
    if(!$order->getId()):
      $orderModel = Mage::getModel('sales/order')->load($order->getId());
       $orderModel->setState(Mage_Sales_Model_Order::STATE_NEW, true);
       $orderModel->setId($order->getId());
       $orderModel->save();
    endif;

  • If I do an echo $order->getId() I got the right id, so it works I also get the parent_id from $getOrder->getData('relation_parent_id'). Commented Feb 6, 2017 at 12:10
  • this line ` $OldOrder->setState(Mage_Sales_Model_Order::STATE_CANCELED, true)->save()` is the problem Commented Feb 6, 2017 at 12:10
  • better to use sales_order_place_after because order is not saved in sales_order_save_after
