Siddhi non-occurrence pattern cannot be used with non source stream

[xtrmstep]

Hi all,

I'm using siddhi 5.1.2 in Docker.

I'm observing a limitation of this pattern to work only with sources. I mean if I've got two patterns an one is dependent on the other , I need to slice Siddhi application into two different applications just to make sure non-occurrence events are detected. If I'm using a single application and composing two dependent patterns inside it, it doesn't detect them.

Example is here http://binary-notes.ru/siddhi-non-occurrence-event-in-data-stream/

Can it be fixed so that any stream is possible to be used?
