Flowable Engine

My user set two same sequenceFlow from startEvent to the same UserTask unintentionally；

And then runtimeService create two tasks which is not meant；

I test the model with ProcessValidator and it succeeds；

Why is it valid?

Hi @orangecj

This is valid by BPMN 2.0 specification:

Multiple outgoing, unconditional sequence flows behave like a parallel gateway split.
