[jboss-user] [JBoss jBPM] - problems creating task instances
Hi,
I'm having a problem creating task instances, specifically for the 1st task node in
the fairly simple workflow I've created. I can create the first task ok, and I can end
it, and save the instance.
However upon creating the context again and reloading the process instance, things go
badly - I can't create a task instance from there.
Here is a JUnit4 test case that illustrates what I am trying to do, and the
processdefinition.xml is below. If anyone can point out what I'm doing wrong or point
me in the right direction, I'd be most grateful.
| @Test
| public void nativeTaskInstanceCommits() {
| File f = TestFiles.getFile("SimpleWorkflow");
| JbpmContext context = JbpmConfiguration.getInstance().createJbpmContext();
|
| try {
| jbpmContext.setActorId("user");
| ProcessDefinition processDefinition = ProcessDefinition.parseXmlReader(new
FileReader(f));
| context.deployProcessDefinition(processDefinition);
|
| ProcessInstance processInstance = new ProcessInstance(processDefinition);
| context.save(processInstance);
|
| TaskInstance taskInstance =
processInstance.getTaskMgmtInstance().createStartTaskInstance();
| Long id = processInstance.getId();
| Assert.assertTrue("startTask".equals(taskInstance.getName()));
| taskInstance.end();
| context.save(taskInstance);
| context.close();
|
| context = JbpmConfiguration.getInstance().createJbpmContext();
|
| //this doesn't seem to work for me
| processInstance = context.loadProcessInstanceForUpdate(id);
| taskInstance = processInstance.getTaskMgmtInstance().createTaskInstance();
| Assert.assertTrue("firstTask".equals(taskInstance.getName()));
|
| List<?> list = taskInstance.getToken().getNode().getLeavingTransitions();
|
| for(Object o : list) {
| Transition trans = (Transition)o;
| String name = trans.getName();
| Assert.assertTrue( (name.equals("finish")) || (name.equals("to
taskNode2")) );
| }
|
| taskInstance.end("finish");
|
Assert.assertTrue("end".equals(taskInstance.getToken().getNode().getName()));
|
| } catch (RuntimeException e) {
| Assert.fail(e.getMessage());
| }
| catch (Exception e) {
| Assert.fail(e.getMessage());
| }
| }
