... 9 common frames omitted
what I'm doing:
I'm trying to access recoveryRunning at onTransition handler:
onTransition {
case _ -> S_Begin =>
loggerScenario.write(ScenarioTraceItem(
sStage = S_Begin.identifier,
sEvent = Some("startWith")
), recoveryRunning)
}
while having
startWith(S_Begin, StateData())
Is it a bug or right behavior?
Thanks,
Nikolay
