When receiving an order where one or more items have no itemtype set, there is the usual "internal server error" from Plack. The Plack error log shows: item-level_itypes set but no itemtype set for item (3) at /home/vagrant/kohaclone/Koha/Schema/Result/Item.pm line 698. Can't call method "description" on an undefined value at /home/vagrant/kohaclone/acqui/orderreceive.pl line 150. To test: - Create a basket - Create an order (AceCreateItem set to 'on order') with multiple items - Make sure one or more of the items have no itemtype set - Close basket - Receive shipment - Try to receive one or more items from the order - Verify error shows For on order items it might make sense to allow an empty itemtype - libraries might want to decide about that when the items arrive.
