Partial payments or installment payment not working in payment selection

1. Create Payment term named as 25% installment

2. Create 4 Schedule lines each having percentage as 25% and net days as 30, 60, 90, 120 respectively

3. Create Invoice (Vendor) for business partner Patio Fun, Inc and payment rule as "On Credit" and Payment term as created in #1 (25% Installment)

4. Create a Invoice line for a product Azalea Bush and make the qty as 10, unit price as 100 and tax as Exempt.

5. This would make a grand total of $1000

6. Complete Invoice (Vendor)

7. Goto Payment Selection (Manual) window ( this happens in Payment Selection window as well)

8. Select business partner as Patio Fun, Inc

9. List will show 4 payments of the invoice created above with payment amount as $250 which is correct

10. Now select the first due payment of $250 and process it.

11. Now refresh payment selection (Manual), all other pending payments of $250

    are gone

Attached is the patch for Payment selection (manual) and I am working on Payment Selection window
