>             Project: Flink
>          Issue Type: Bug
>          Components: CEP
>    Affects Versions: 1.1.2
>            Reporter: Michał Jurkiewicz
>            Assignee: Kostas Kloudas

> I configured the following flink job in my environment:
> {code}
> Pattern<Event, ?> patternCommandStarted = Pattern.<Event> begin("event-accepted").subtype(Event.class)
> .where(e -> {event accepted where statement}).next("second-event-started").subtype(Event.class)
> .where(e -> {event started where statement}))
> .within(Time.seconds(30));
> DataStream<Either<Event, Event>> events = CEP
>   .pattern(eventsStream.keyBy(e -> e.getEventProperties().get("deviceCode")), patternCommandStarted)
>   .select(eventSelector, eventSelector);
> static class EventSelector implements PatternSelectFunction<Event, Event>, PatternTimeoutFunction<Event, Event> {}
> {code}
> The problem that I have is related to timeout handling. I observed that: 
> if: first event appears, second event not appear in the stream  
> and *no new events appear in a stream*, timeout handler is not executed.
> Expected result: timeout handler should be executed in case if there are no new events in a stream
