Task changes priority after SignalBoundary

Question

I have a UserTask that can optionally be cancelled by firing a Signal. When the Signal is actually received the Task seems to change its Priority from HIGH to LOW. Why does that happen?

Accepted Answer

SignalBoundaries on a UserTask are normally used to Expire a Task on an exceptional path. So it is a feature, that the state of this Task can be adjusted by configuring an expiry Priority.

However if you don't like that behaviour you can change the priority back to its original state within the SignalBoundary event that handles the signal:

List<ITask> destroyed = signal.getDestroyedTasks();
ITask last = destroyed.get(destroyed.size()-1);
ivy.task.setOriginalPriority(last.getOriginalPriority());
