    JBPM 5.4 - send signal event to reusable subprocess

    Zeca9 ... Newbie




      I've a main process with a reusable subprocess:


      The reusable subprocess calls a process that has a catch signal event.


      When I launch the Main, I save the process instance id (idMain) in my own DB. But I don´t know anything about the id of the subprocess. That's the problem.



      Because I'm using the same session to start all the main process, when I want to signal the event whitin the subprocess for one single instance, i can't just do:

      ksession.signalEvent(event, params);

      because that will trigger all the instances and not just one.


      I tried to pass the id of the main (parent process) using the command:

      ksession.signalEvent(event, params, idMain);

      but nothings happens.


      I also found that this works

      ksession.signalEvent(event, params, idSubprocess);

      but like I said, I don't have the idSubprocess.



      Another way i tried was trying to transform the signalRef attribute unique using a variable (id_main) in the invocation of the subprocess, that will be used in the parameter signalRef=event.#{id_main}. Didn't work beacuse the value wasn't replaced.



      Can anyone point me to the right direction?



      Is any way to get the idSubProcess knowing only the IdMain?



      Or is a way to use a script task before the signal event just to update the signalEvent parameter?
