The problem is that when a row is deleted from the Vector, how should the current_row value be adjusted? Currently nothing happens so current_row effectively points to the next row so that when next() is called that row is skipped. Simply decrementing current_row on a delete won't work because it introduces the exact same problem except with previous(). When I looked at this problem before I wanted to see if a cleaner solution presented itself than adding a new variable like "boolean onDeletedRow" that would need to be checked or reset in a significant number of places, but perhaps that's the only way to go.
