List all user tasks from bpm file

darshan_hardas — Thu, 23 May 2013 04:51:00 GMT

We have a requirement to list all the user task/tasks defined for a process from an BPM file. I have used the TaskService query filtered with process instance id but all task are not listed.String processInstanceId = processInstance.getId();List<Task> instanceTaskList = taskService.createTaskQ

The taskservice will only give you existing tasks. The historyservice will only give you completed tasks.

Use the following method on the RepositoryService to get a POJO representation of your process, allowing you to get all user tasks defined in the process:

<code>
/**
   * Returns the {@link BpmnModel} corresponding with the process definition with
   * the provided process definition id. The {@link BpmnModel} is a pojo versions
   * of the BPMN 2.0 xml and can be used to introspect the process definition
   * using regular Java.
   */
BpmnModel getBpmnModel(String processDefinitionId);
</code>

Thanks for the response .

Below is the code I have used

<code>
ProcessDefinitionEntity processDefinition =
    (ProcessDefinitionEntity) ((RepositoryServiceImpl) repositoryService).getDeployedProcessDefinition(processInstance.getProcessDefinitionId());

        if (processDefinition != null) {
            for (ActivityImpl activity : processDefinition.getActivities()) {
              String type = (String) activity.getProperty("type");
              String name = (String) activity.getProperty("name");
              String taskId = activity.getId();

              System.out.println("test "+type+" name "+name + " id: " + taskId);


            }
        }
</code>

Make sure the class you are referencing is on your classpath (the jar containing the .class-file or the .class-file itself) and double-check the fully-qualified name of the class is correct..

Next time, create new topics for now questions instead of piggy-backing on old ones, may be lost otherwise…

Not slow. Just very few people use CDI it seems.

Thanks in Advance.
