Hi,
Actually I can have an incoming in my editor. But I see in the user guide where it says that "A Signal Event should have no incoming connections and one outgoing connection. "
I tried to test the one with incoming arrow, and it appears to function like the previous process will step in a waiting status for defined signal, and this event will only react to the signal sent by the previous step.
Plz let me know if my understanding is correct on this.
