I tried this and was able to run it inspite of a small error in your processdefinition (task2 is in the processstate ;-) ) You signal the 'child-token' which is in the proces-state node, not in the subprocess itself. So to me ending that does not signal any parent node. It does transition this specific token to the next one. I think that should maybe not happen but still... If you want the subprocess to end and not signal the parent token, then end the rootToken of the subprocess with end(false) like processInstance.getRootToken().getChild("transition1").getSubProcessInstance().getRootToken().end(false); If I adapt the unittest this does exactely what you want ProcessInstance processInstance = jbpmContext.newProcessInstance("MainProcess"); | processInstance.signal(); | | assertNull(processInstance.getTaskMgmtInstance().getTaskInstances()); | | assertEquals("subProcess1", processInstance.getRootToken().getChild("transition1").getNode().getName()); | | // Abort one of the subprocesses | processInstance.getRootToken().getChild("transition1").getSubProcessInstance().getRootToken().end(false); | | assertNull(processInstance.getTaskMgmtInstance().getTaskInstances()); | assertTrue(processInstance.getRootToken().getChild("transition1").getSubProcessInstance().getRootToken().hasEnded()); | assertFalse(processInstance.getRootToken().getChild("transition1").hasEnded()); | assertEquals("subProcess1", processInstance.getRootToken().getChild("transition1").getNode().getName()); | View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4201537#...
