But I don´t know anything about the id of the subprocess. That's the problem.</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>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:</p><p><em>ksession.signalEvent(event, params);</em></p><p>because that will trigger all the instances and not just one.</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>I tried to pass the id of the main (parent process) using the command:</p><p><em>ksession.signalEvent(event, params, idMain);</em></p><p>but nothings happens.</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>I also found that this works</p><p><em>ksession.signalEvent(event, params, idSubprocess);</em></p><p>but like I said, I don't have the idSubprocess.</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>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.</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>Can anyone point me to the right direction?</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>Is any way to get the idSubProcess knowing only the IdMain? </p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>Or is a way to use a script task before the signal event just to update the signalEvent parameter?</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>Thanks</p></div>
