jbpm 4.1 - execution not waiting for Task Form inputs

[makarandk502]

Hi,
Simple process definition( with a taskform ) when run using jbPM APIS is not getting stopped at task form node but it completes its execution.
I am trying to test the process using jBPM APIs not console.
Code attached below for reference.

Process should wait for user inputs through a form which is attached to "review" task. I also tried removing line " taskService.completeTask(task.getId());"
from jbpm test case but no sucsess.

Can anybody guide me in this regard ?

Process definition :

<?xml version="1.0" encoding="UTF-8"?>

<process name="FormDynamic" xmlns="http://jbpm.org/4.0/jpdl">

 <start g="20,20,48,48">
 <transition to="review"/>
 </start>

 <task assignee="peter" form="org/jbpm/examples/formdynamic/givedetails.ftl" g="96,16,127,52" name="review">
 <transition to="wait"/>
 </task>
 <state g="268,24,96,31" name="wait"/>

</process>

jbpm test case :

package org.jbpm.examples.formdynamic;

import java.util.HashMap;
import java.util.List;
import java.util.Map;

import org.jbpm.api.ProcessInstance;
import org.jbpm.api.task.Task;
import org.jbpm.test.JbpmTestCase;

public class FormDynamicTest extends JbpmTestCase {
 String deploymentId;

 protected void setUp() throws Exception {
 super.setUp();

 deploymentId = repositoryService.createDeployment()
 .addResourceFromClasspath("org/jbpm/examples/formdynamic/FormDynamic.jpdl.xml")
 .deploy();
 }

 protected void tearDown() throws Exception {
 repositoryService.deleteDeploymentCascade(deploymentId);

 super.tearDown();
 }

 public void testTaskAssignee() {
 Map<String, Object> variables = new HashMap<String, Object>();
 variables.put("order", "johndoe");
 ProcessInstance processInstance = executionService.startProcessInstanceByKey("FormDynamic", variables);
 String pid = processInstance.getId();
 //ProcessInstance processInstance = executionService.startProcessInstanceByKey("FormDynamic");
 List<Task> taskList=taskService.findPersonalTasks("peter");
 Task task=taskList.get(0);

 taskService.completeTask(task.getId());

 System.out.println("List is"+taskList);

 // verify that process moved to the next state
 processInstance = executionService.findProcessInstanceById(pid);
 assertTrue(processInstance.isActive("wait"));



 }
}

Hi makarandk502,

if I remove the
taskService.completeTask(task.getId());

and change the assert to check for "review" instead of "wait" the tests works for me. I only had a 4.0 to hand, not 4.1 but I think this should work in 4.1....

.......
 Task task=taskList.get(0);

 //taskService.completeTask(task.getId());

 System.out.println("List is"+taskList);

 //verify that process moved to the next state
 processInstance = executionService.findProcessInstanceById(pid);
 assertTrue(processInstance.isActive("review"));

regards!

Hi,

Even in my case, its reaching at "review" task. print statements like "List is[Task(review)]" But in "review" task, we have associated a form which can be viewed in jbpm console. Ideally we should view the form and once we enter "submit" , it should proceed further. Basically it is not waiting for user inputs in taskform

But I am not able to see the form in jbpm console and it is deleting process instance. I am attaching jbpm test case result below.

Correct, since your unittest ends (how can the test know it has to wait for something..... If you e.g. build in a Thread.sleep(1000) loop endlessly and check in the loop if the task has ended (do a break then) it could work. That is *not* the way unittests are *normally* used though. The user is also 'simulated' in the unittest.
