I need to tweak magento admin so after a new invoice is created at a link like this:
admin/sales_order_invoice/new/order_id/550/
to redirect to
/admin/sales_order_invoice/view/invoice_id/384/order_id/550/
Right now, after an order is created magento redirects to admin/sales_order/view/order_id/542/
L.E.
Found out that redirect url is set in saveAction() from app/code/core/Mage/Adminhtml/controllers/Sales/Order/InvoiceController.php
Does anyone know a way to retrieve created invoiced inside that function?
