Hello Doug,
yes, this history implementation records every event in the engine.
You could write:
---8<---
history = dashboard.history.by_process(wfid)
p history.select { |h|
h['action'] == 'dispatched'
}.collect { |h|
h['participant_name']
}
--->8---
That'll only display the participant for 'dispatched' messages (emitted by
the engine we it has successfully handed a workitem to a participant).
You could also replace the history by your own implementation only keeping
track of the events you care for.
