Does anyone know why, if two records with equivalent values (ie. same dates) are sorted using the RecordComparator by those values, the second value entered always comes before the first one in the final sorted order.
It seems that it should work the opposite such that if two values (which the RecordComparator is sorting by) are equivalent, the most recently added value would be returned after the previous one of equivalent value in the final sorted order.
To try and solve this problem, I tried making the "equivalent" case in the RecordComparator's compare function return "PRECEEDS" instead of "EQUIVALENT", but this only caused other problems and greatly disturbed the sorted order.
If anyone knows why this design decision was made or has any ideas on how to reverse the order in which two equivalent values are returned in for enumeration, I'd greatly appreciate your help.
I agree. Here's the link:
