Magento更新订单送货地址

Question

At the end of the purchase, the user has the possibility to change your shipping address. Im trying to update this information, but it dosen't work. This is my code:

$customer = Mage::getModel('customer/session')->getCustomer();
$order = Mage::getSingleton('checkout/session')->getLastOrder();
$postData = Mage::app()->getRequest()->getPost();

$_new_address = array (
    'firstname' => $postData['nombre'],
    'lastname'  => $postData['apellidos'],
    'street'    => array ('0' => $postData['direccion']),
    'city'      => $postData['localidad'],
    'region_id' => $postData['provincia_id'],
    'region'    => '',
    'postcode'  => $postData['codigo_postal'],
    'country_id'=> 'ES',
    'telephone' => $postData['telefono']
);

$customAddress = Mage::getModel('customer/address');
$customAddress->setData($_new_address)
    ->setCustomerId($customer->getId())
    ->setIsDefaultBilling('1')
    ->setIsDefaultShipping('1')
    ->setSaveInAddressBook('1');

// Save address
try {
    $customAddress->save();
} catch (Exception $e) {
    Mage::getSingleton('core/session')->addError($e->getMessage());
    header('Location: /');
    exit;
}

// Update the order
try {
    $order->setShippingAddress($customAddress)->save();
} catch (Exception $e) {
    Mage::getSingleton('core/session')->addError($e->getMessage());
    header('Location: /');
    exit;
}

Can I update an order or is not allowed? Can anyone give me a tip?

My problem was that the Billing address and shipping address in the order, are different than having the user has as default addresses.

At the end the code looks like this:

$order = Mage::getSingleton('checkout/session')->getLastOrder();

$postData = Mage::app()->getRequest()->getPost();

// Try to get shipping and billing address data.
$orderShippingAddress = $order->getShippingAddress()->getId();
$orderShipping = Mage::getModel('sales/order_address')->load($orderShippingAddress);

$orderBillingAddress = $order->getBillingAddress()->getId();
$orderBilling = Mage::getModel('sales/order_address')->load($orderBillingAddress);

// Updating data.
$orderShipping->addData($postData);
$orderBilling->addData($postData);

try {
    $orderShipping->implodeStreetAddress()->save();
    $orderBilling->implodeStreetAddress()->save();
} catch (Exception $e) {
    Mage::logException($e);
    Mage::getSingleton('core/session')->addError($e->getMessage());
    header('Location: /after/success/envio');
    exit;
}

Now, it works. Thanks for your help @R.S
