Description

If you're in the WRP suite and repeatedly execute a workflow, this NPE sometimes occurs with each execution. WRM does not show up in the stacktrace, but I'm fairly positive it's something to do with how WRM is using TableSorter. Afaict this bug doesn't cause any harm (let me know if you notice otherwise). Putting on 2.0 target since it's possible I may have to modify TableSorter:
