Hi agrawalanish.

before starting the process, how to retrieve all the activities (user task, sub process, email task) for this process and allow admin of our application to assign custom role for each one. during execution use this custom role and allow users having this role from my database to claim and complete the task. how to achieve this.

You can start process with variables and use variables in candidateGroups for tasks.
To get list of tasks for the process you can get them from BPMNModel (as an example you can use ProcessDiagramGenerator).

Also want to understand how to achieve below -

a maker

What is it a maker?

multiple reviewers
multiple approvers

You could do that with several different ways.
One of them could be to use MultiInstance tasks.

Martin

Thanks a lot Martin.

I am a beginner in Activiti.

To get list of tasks for the process you can get them from BPMNModel (as an example you can use ProcessDiagramGenerator).
Anish: Is it possible to provide a sample example for this?

What is maker?
Anish: Maker is the user (with specific role) who can create a record for review and approval by other users.

Hi,

Anish: Is it possible to provide a sample example for this?

Based on ProcessDefinitionId (you can get it from the process instance), you can get process definition. Process definition contains list of activities.

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

        for (ActivityImpl activity : processDefinition.getActivities()) {
        …..
        }
</code>

Thanks a lot Martin.

Is it possible to assign a custom role for each activity while displaying the list of activities to our admin?

Say I have a multi instance activity to which I want to assign a custom role and multiinstances should be created for each user having this role. Please let me know how to achieve the same.

create list of users with specified role
put this list to the MultiInstanceLoop
user task in the multiinstance instance loop can address loopCounter (or loopIndexVariable) and fetch item from the list - do it in the expression and use this expression as assignee.

(I personally do not like assigning tasks directly to the users. (Vacations,….) )

could you please tell me the entire process to deploy code

Hi.
you can find example in the activiti tests


  @Deployment
  public void testParallelUserTasksBasedOnCollection() {
    List<String> assigneeList = Arrays.asList("kermit", "gonzo", "mispiggy", "fozzie", "bubba");
    String procId = runtimeService.startProcessInstanceByKey("miParallelUserTasksBasedOnCollection",
          CollectionUtil.singletonMap("assigneeList", assigneeList)).getId();
    
    List<Task> tasks = taskService.createTaskQuery().orderByTaskAssignee().asc().list();
    assertEquals(5, tasks.size());
    assertEquals("bubba", tasks.get(0).getAssignee());
    assertEquals("fozzie", tasks.get(1).getAssignee());
    assertEquals("gonzo", tasks.get(2).getAssignee());
    assertEquals("kermit", tasks.get(3).getAssignee());
    assertEquals("mispiggy", tasks.get(4).getAssignee());
    
    // Completing 3 tasks will trigger completioncondition
    taskService.complete(tasks.get(0).getId());
    taskService.complete(tasks.get(1).getId());
    taskService.complete(tasks.get(2).getId());
    assertEquals(0, taskService.createTaskQuery().count());
    assertProcessEnded(procId);
  }

how to configure h2 databse with activiti

Re: Immediate help needed

cshar — Tue, 02 Jun 2015 20:44:46 GMT

how can we add custom roles and give them permissions (read/ write)? Also will that be available in a activiti diagram while defining tasks?

Re: Immediate help needed

jbarrez — Thu, 11 Jun 2015 14:31:23 GMT

Roles match the candidate group concept in Activiti. They are set in the modeling tool, but are not visualized graphically.
Read/write permissions are not in Activiti, you'd need to add that in your logic above Activiti.
