Cancelled OrderItems are still included in the calculation of the order price.
Tested with release 16.11, revision: 1781126
Steps to reproduce:
1. Setup a fresh OFBiz and do loadDefault
2. Go to the Order Manager and cancel the only existing demo order named DEMO10090 here: https://localhost:8443/ordermgr/control/orderview?orderId=DEMO10090
3. The "Total Due" at the bottom right still states 38.36$. It should be 0$ because all the items got cancelled.
The error is probably in OrderView.groovy line 119: OrderReadHelper.getOrderGrandTotal(orderItems, orderAdjustments)
This method apparently includes cancelled OrderItems in the grandTotal.
