[jboss-user] [jBPM] - JBPM 5.4 - boundary signal event to abort reusable subprocess stopped in a Human Task

Jose Pereira [https://community.jboss.org/people/zeca9] created the discussion "JBPM 5.4 - boundary signal event to abort reusable subprocess stopped in a Human Task" To view the discussion, visit: https://community.jboss.org/message/827709#827709 -------------------------------------------------------------- Hi, I'm new in Jbpm and beacuse of that, struggling to get something work :) Let me explain: I've a *main* process with a reusable subprocess that have a boundary signal event: https://community.jboss.org/servlet/JiveServlet/showImage/2-827709-21129/... https://community.jboss.org/servlet/JiveServlet/downloadImage/2-827709-21... The reusable *subprocess* calls a process that have a script, a catch signal event and a human task: https://community.jboss.org/servlet/JiveServlet/showImage/2-827709-21130/... https://community.jboss.org/servlet/JiveServlet/downloadImage/2-827709-21... *CASE 1: Perfect!* When I launch a instance by API: +ProcessInstance processInstance = ksession.startProcess("Process_Name", params);+ everything works like expected. The instance stops in signal event from the *subprocess*, waiting to be fired. Then I signal the boundary event from the *main* process; +ksession.signalEvent(boundary_event, params, idMain);+ and again the result is the expected: The *subprocess* is aborted and *main* jumps to the next task (Scrip Task 1). *CASE 2: Error!* I start the instance like in case 1, but this time I signal the event of the subprocess, making this go foward to the human task TESTE_SUB. Then I signal the boundary event from the *main* process (just like in case 1) and I get a error!!!
