[jboss-user] [JBoss jBPM] - subprocess token positioned at next node
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>
|
| <bean name="jbpm.sub.process.resolver"
class="com.jbpm.tutorial.subprocess.CustomSubProcessResolver"
singleton="false" />
|
| </jbpm-configuration>
