subprocess token positioned at next node

[debnathm]

Hi

I am trying to execute a subprocess but after signalling the main
process, the token seems to go past the first state of the subprocess
and position itself at the second state. I was expecting it to stop at
the first state of the subprocess.

The print statements after executing the test case are as below:

After processInstance
Node is: ProcessState(process-state1)
Subprocess node is:fork1

Please let me know what's wrong.

Thanks,

Debnath

The test case and setup details are as follows:

Test case

package com.jbpm.tutorial.subprocess;

import junit.framework.TestCase;
import org.jbpm.graph.def.ProcessDefinition;
import org.jbpm.graph.exe.ProcessInstance;
import org.jbpm.graph.exe.Token;
import org.jbpm.graph.node.ProcessState;

public class SubProcessTest extends TestCase {
 public void setUp()
 {

 }

 public void testSubProcess()
 {
 ProcessDefinition mainprocessDefinition = ProcessDefinition.parseXmlString(
 "<process-definition name='mainprocess'>" +
 "<start-state name='start'>" +
 "<transition to='process-state1'></transition>" +
 "</start-state>" +
 "<process-state name='process-state1'>" +
 "<sub-process name='subprocess'></sub-process>" +
 "<transition to='task-node1'></transition>" +
 "</process-state>" +
 "<task-node name='task-node1'>" +
 "<task name='TaskNode1Task'></task>" +
 "<transition to='end'></transition>" +
 "</task-node>" +
 "<end-state name='end'></end-state>" +
 "</process-definition>");
 ProcessInstance mainprocessInstance = new ProcessInstance(mainprocessDefinition);
 System.out.println("After processInstance");

 assertEquals(false, mainprocessInstance == null);
 Token token = mainprocessInstance.getRootToken();
 token.signal();
 assertEquals(true, token.getNode() instanceof ProcessState);
 System.out.println("Node is: " + token.getNode());
 ProcessInstance subProcessInstance = token.getSubProcessInstance();
 Token subprocessToken = subProcessInstance.getRootToken();
 System.out.println("Subprocess node is:" + subprocessToken.getNode().getName());
 assertEquals(true, subprocessToken.getNode().getName().equals("start"));
 //System.out.println("Subprocess node is:" + subprocessToken.getNode().getName());
 }
}

The Subprocess Resolver is as follows:

package com.jbpm.tutorial.subprocess;

import org.jbpm.graph.node.SubProcessResolver;
import org.jbpm.graph.def.ProcessDefinition;
import org.dom4j.Element;

public class CustomSubProcessResolver implements SubProcessResolver
{

 /**
 *
 */
 private static final long serialVersionUID = 1L;

 public ProcessDefinition findSubProcess(Element subProcessElement)
 {
 ProcessDefinition subprocessDefinition = ProcessDefinition.parseXmlString(
 "<process-definition name='subprocess'> " +
 "<start-state name='start'> " +
 "<task name='StartNodeTask'> " +
 "<assignment actor-id='user'></assignment> " +
 "</task>" +
 "<transition to='fork1'></transition>" +
 "</start-state>" +
 "<fork name='fork1'>" +
 "<transition to='task-node1' name='to_task_node_1'></transition>" +
 "<transition to='task-node2' name='to_task_node_2'></transition>" +
 "</fork>" +
 "<task-node name='task-node1'>" +
 "<task name='TaskNode1Task'>" +
 "<assignment actor-id='user'></assignment>" +
 "</task>" +
 "<transition to='join1' name='to_join_1'></transition>" +
 "</task-node>" +
 "<task-node name='task-node2'>" +
 "<task name='TaskNode2Task'>" +
 "<assignment actor-id='user'></assignment>" +
 "</task>" +
 "<transition to='join1' name='to_join_2'></transition>" +
 "</task-node>" +
 "<join name='join1'>" +
 "<transition to='end'></transition>" +
 "</join>" +
 "<end-state name='end'></end-state>" +
 "</process-definition>");
 return subprocessDefinition;
 }

}

The jbpm.cfg.xml is as follows:

<jbpm-configuration>
