Hi again,
I have some more informations about my problem:
the process is started as a reusable sub-process by another process; if the parent process send the event, I got the error.
The event is sent in a script task with this code:
kcontext.getKnowledgeRuntime().signalEvent("abort",null,subProcId);
I tried to change the process to send the signal event by the process itself and not by the parent

and everything works fine.
Where I'm wrong?
Antonio
