To repeat: Probably not repeatable, but I ran the restart op on a unix RHQ Agent Launcher service. See screenshot - the operation status shows as "in progress" and "success" at the same time. Probably a timing issue where the two tables render at different times and see different data. maybe should somehow render the "completed" table first to avoid this problem.
On further reflection, rending the 'completed' table first wouldn't solve the problem, it would just cause the op to not show up at all, rather than twice.
