API for Activiti explorer functionality

sarbx

Hello,

I'm trying to find out if all the functionality exposed in 'Activity Explorer' like,

- Subtasks
- event stream/discussions
- Transfer and Reassign functionality
- Creating standalone cases

are available through the Activiti API's?

If they are could you please give pointers to those APIs.

We have a requirement that after a task is assigned to a user, there will lots of back and forth between the current owner of the task and the person who started the process. How is this scenario to be modeled in BPMN/Activiti.

Thanks for your help.

The source of the explorer is also open… Why don't you check that out?

I did spend some time reading the docs/api and 'Activiti in Action' ebook and found the corresponding mapping for my request,

Subtasks - using the ParentTaskId
event stream/discussions - using the Comments on Tasks or Process instance
Transfer and Reassign functionality - Using Delegation PENDING/RESOLVED
Creating standalone cases - Creating tasks without a Process instance

So I'm good on these questions.

But I'm still confused with back and forth between the process initiator and one of the task assignee downstream. Take the following vacation process request as example,

- Employee submits the number of days of vacation as part of StartFormData of 'Vacation Request' process
- A 'Decide' task (taskA) is assigned to the manager to make a decision on the vacation request.
- The manager should be able to 'Approve', 'Reject' or 'Request Edit' of the vacation days.
- On 'Request Edit' a task (taskB) should be assigned to the employee. The employee can change the days and the 'Decide' task should be assigned back to the 'Manager'
- And this back and forth can happen multiple times.

My confusion is what should happen when the Manager selects 'Request Edit',

- Should taskB be created as a dynamic 'Sub Task' of taskA
- Or should I model the taskB at design time and have some kind of loop connecting these two tasks.

Hi,

That's up to your preference.
But as you describe it I would model it at design time.
Sub tasks etc is more useful when you want to split up a larger piece of work.

Best regards,
