How to get the finished, pending and upcoming tasks in the workflow at runtime?

As we transition to the new Hyland Community, some post links may be temporarily disrupted as we finalize redirects. We apologize for the inconvenience and are working to resolve this as quickly as possible. Details.

We have the following model:
Start -> Service Task -> User Task -> Mail Task -> End
Suppose the current task under execution is User Task, is there a way to get the list of tasks that have been completed before this User Task(Service Task according to our model)
and the upcoming tasks that need to be executed after the completion of this User Task(Mail Task according to our model)
and unfinished tasks(suppose the mail task doesn't get triggered as the user has not completed the task assigned to him).

We have tried using "historyService.createHistoricActivityInstanceQuery().finished().processInstanceId(processid).list();" and "historyService.createHistoricActivityInstanceQuery().unfinished().processInstanceId(processid).list();"
but it fetches the task list only after the process is instantiated and completed and not during runtime.

Hi,

is there a way to get the list of tasks that have been completed before this User Task(Service Task according to our model)

use http://activiti.org/userguide/index.html#history and HistoryService queries

and the upcoming tasks that need to be executed after the completion of this User Task(Mail Task according to our model)

I see 2 possibilities simulation (crystalball) or you can just simply parse xml file and see the next tasks in the row (BpmnModel stores this information too, you can get it from the repository service)

and unfinished tasks

see previous
