[jboss-dev-forums] [Design of JBoss jBPM] - processInstance.signal DelegationException in a Servlet

I am trying to test a simple processDefinition in servlet...i always get ' DelegationException in processInstance.signal();' org.jbpm.graph.def.DelegationException org.jbpm.graph.def.GraphElement.raiseException(GraphElement.java:352) org.jbpm.graph.def.GraphElement.raiseException(GraphElement.java:346) org.jbpm.graph.def.GraphElement.executeAction(GraphElement.java:249) org.jbpm.graph.def.GraphElement.executeActions(GraphElement.java:212) org.jbpm.graph.def.GraphElement.fireAndPropagateEvent(GraphElement.java:182) org.jbpm.graph.def.GraphElement.fireEvent(GraphElement.java:166) org.jbpm.graph.def.Node.enter(Node.java:301) org.jbpm.graph.def.Transition.take(Transition.java:119) org.jbpm.graph.def.Node.leave(Node.java:383) org.jbpm.graph.node.StartState.leave(StartState.java:70) org.jbpm.graph.exe.Token.signal(Token.java:178) org.jbpm.graph.exe.Token.signal(Token.java:123) org.jbpm.graph.exe.ProcessInstance.signal(ProcessInstance.java:217) org.example.web.WorkflowExcecuteServlet.SimpleNodeActionsFlow(WorkflowExcecuteServlet.java:162) Servlet code looks like this.. DefnString is : <process-definition> <start-state> <transition to=\'start\'/> </start-state> <state name=\'start\'> <event type=\'node-enter\'> <action class=\'org.example.web.MyActionHandler\'/> <event type=\'node-leave\'> <action class=\'org.example.web.MyActionHandler\'/> <transition to=\'end\'/> <end-state name=\'end\' /> </process-definition> ProcessDefinition processDefinition = ProcessDefinition.parseXmlString( defnString ); ProcessInstance processInstance = new ProcessInstance(processDefinition); // The next signal will cause the execution to leave the start // state and enter the state 's'. So the state 's' is entered // and hence the action is executed. processInstance.signal(); Can you someone help me ..what is wrong with this code? thanks BG View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4026704#...
