/**
 * Is invoked when the user clicks on the Retransmit button on both the PO tabbed page and on the Purchase Order
 * Retransmit Document page, which is essentially a PO tabbed page with the other irrelevant tabs being hidden. If it was
 * invoked from the PO tabbed page, if the PO's pending indicator is false, this method will invoke a method in the
 * PurchaseOrderService to update the flags, create the PurchaseOrderRetransmitDocument and route it. If the routing was
 * successful, we'll display the Purchase Order Retransmit Document page to the user, containing the newly created and routed
 * PurchaseOrderRetransmitDocument and a retransmit button as well as a list of items that the user can select to be
 * retransmitted. If it was invoked from the Purchase Order Retransmit Document page, we'll invoke the
 * retransmitPurchaseOrderPDF method to create a PDF document based on the PO information and the items that were selected by
 * the user on the Purchase Order Retransmit Document page to be retransmitted, then display the PDF to the browser.
