<div class="jive-rendered-content"><p>Hi,</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>I'm new in Jbpm and beacuse of that, struggling to get something work <span> :) </span></p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>Let me explain:</p><p>I've a <strong>main </strong>process with a reusable subprocess that have a boundary signal event:</p><p><a href="https://community.jboss.org/servlet/JiveServlet/showImage/2-827709-21129/Teste.png"><span> https://community.jboss.org/servlet/JiveServlet/downloadImage/2-827709-21129/450-236/Teste.png </span></a></p><p>The reusable <strong>subprocess </strong>calls a process that have a script, a catch signal event and a human task:</p><p><a href="https://community.jboss.org/servlet/JiveServlet/showImage/2-827709-21130/TesteSub.png"><span> https://community.jboss.org/servlet/JiveServlet/downloadImage/2-827709-21130/450-126/TesteSub.png </span></a></p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p><span style="font-size: 14pt;"><strong>CASE 1: Perfect!</strong></span></p><p>When I launch a instance by API:</p><p><em>ProcessInstance processInstance = ksession.startProcess("Process_Name", params);</em></p><p>everything works like expected. The instance stops in signal event from the <strong>subprocess</strong>, waiting to be fired.</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>Then I signal the boundary event from the <strong>main</strong> process;</p><p><em>ksession.signalEvent(boundary_event, params, idMain);</em></p><p>and again the result is the expected: The <strong>subprocess</strong> is aborted and <strong>main </strong>jumps to the next task (Scrip Task 1).</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p><strong style="font-size: 19px;">CASE 2: Error!</strong></p><p>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.</p><p>Then I signal the boundary event from the <strong>main</strong> process (just like in case 1) and I get a error!!!</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>Log:</p><p><em>1    12/07 11:03:04,464[main] ERROR
