I recently pushed out an upgrade to 3.15. Previously the purchase order number was populated on the PDF Order details if the PO had a value. Now it is not showing.
I checked the database for my orders and confirmed that the PurchaseOrderNumber field was populated. I then downloaded the latest version of SmartStore.Net from GitHub and ran it in debug mode in Visual Studio 2017 (with the appropriate App_Data files copied over from my production instance). I put a debug point on line 73 of the Details.Print.cshtml page and found that although PurchaseOrderNumber is *not* null in the database, it is showing as null in the paused code.
Any ideas on why this is happening?
