----------------------------------------
Summary: Charges submitted on the same day replay in creation
order instead of due-date order
Key: FINERACT-2898
URL: https://issues.apache.org/jira/browse/FINERACT-2898
Project: Apache Fineract
Issue Type: Bug
Reporter: Piotr Wargulak
On progressive loans, ChangeOperation#compareTo orders charges by effective
date, then by submitted date, then by creation time. Two charges submitted on
the same day therefore replay in creation order.
When a payment made before that day is reprocessed, it is applied to those
charges in that order. A charge due later can then be paid ahead of one due
earlier. The order of rows in the loan's charge set is not meaningful, so the
outcome can differ between otherwise identical loans.
Steps to reproduce:
Create a progressive loan.
Add several specified-due-date fees on the same day, in an order different from
their due dates.
Post an in-advance payment dated before that day.
Observe which fees it pays.
Proposed fix: when both operations are charges with equal effective and
submitted dates, compare their due dates (nulls last) before falling back to
creation time. Add a unit test with charges created out of due-date order.
