Creating Invoice & Capturing on Shipment

Question

We've got some API integrations that will periodically create shipments for orders.

What I'd like to do is create an observer to also create an appropriate invoice & capture payment when this shipment is created. I have this tied to sales_order_shipment_save_after:

public function autoInvoice($observer){

    $shipment = $observer->getEvent()->getShipment();
    $order = $shipment->getOrder();

    $items = $shipment->getItemsCollection();

    $qty = array();

    foreach($items as $item)
        $qty[$item['order_item_id']] = $item['qty'];

    $invoice = Mage::getModel('sales/order_invoice_api');

    $invoiceId = $invoice->create($order->getIncrementId(), $qty);

    $invoice->capture($invoiceId);

}

(The code for the actual capture is somewhat naive, but bear with me.)

What's strange is that this code works just fine -- the shipment is created, the invoice is created and marked as 'Paid.' However, the order itself stays in limbo and retains a status 'Pending.'

Looking into it further, the items on the order itself have the correct quantities for both Ordered and Shipped, but there's no listing of the quantity Invoiced. I think this is what's causing the status hangup. It's as though the qty_invoiced on the sales_order_item table is getting reverted somehow.

Again, the Invoice shows the right items, so I'm quite confused here.

Any ideas?

This is indeed a very interesting one @bahoo.

maybe try:

$shipment = $observer->getEvent()->getShipment();
$order = $shipment->getOrder();

$qty = array();

$invoice = Mage::getModel('sales/order_invoice_api');
$invoiceId = $invoice->create($order->getIncrementId(), $qty);

$invoice->capture($invoiceId);
