Afte completing a product split into serial numbers on a delivery order, the delivery order isnt updated and still shows the unsplit product. Only once u go to list view and back to the individual item can see the split product.

1. Create Delivery Order.
2. Add product with qty 3
3. Split product into individual serial numbers (once complete notice that delivery order doesnt show split items)
4. Go to delivery order list view
5. Click on new delivery order
6. See that individual lots for that product with serial numbers. (this is what i expected to see after step 3).
