Getting the process ID of a called subprocess

Dear community,I need some help with the following scenarioescription of the situation:I have got two processes, one parent process and one subprocess which is triggered by its parent via a call activity. The subprocess contains multiple user tasks where the user has to input various values. All p

If I understand you correctly you do not need subprocess id for completing its tasks. When the state transfers from parent to sub-process you have at least one task (assuming the subprocess is not completely wait-state free) and calling:

Task task = taskService.createTaskQuery().processInstanceId(processInstance.getId()).singleResult();

with the processInstance which is your parent process you will get your task waiting for user action. As I know there is no REST/API method to complete subprocess completely. You need to complete subprocess's tasks one by one.
You need to check whether your process state is inside subprocess or not when you tried to call "Get open tasks for a process instance".

That is exactly what I wanted. But no, that does not work. It gives me an NPE when using Java and an empty JSON object when using the REST API.

Hmmm , seems to me the process instance details request should be enhanced to include that data … could you create a JIRA request for this?

In rest, use process-instances?superProcessInstanceId=123 (see http://www.activiti.org/userguide/#restProcessInstancesGet). In java, there is a query-counterpart. This way, you can get the called process-instance. The other way around is also supported using subProcessInstanceId.

Hi, I have similar scenario , I need to query for all the active user tasks including from Sub process (Call Activity). When I query the task service using process Instance Id, I get only parent process user tasks. How to achievet that?

There is no single query, for the moment, to do this. Alternative is to either 1) do a native task query (see API), 2) do multiple queries or 3) add jira requesting this feature, perhaps suggesting solution with pull-request

Here is the work around we are using for this (see last post). It took me a few days to put all of the pieces together.

Activiti Team, this scenario seems to come up quite a bit in these forums.
The use case is described perfectly by the OP where the deployment model is to use
Activiti in a "headless mode" where Activiti is only used for process orchestration and not for the UI/Forms.

It would save some of us a lot of head scratching if there was an official way to handle this and if it was
described as a usage scenario in the user guide.

We should indeed consider enriching the task-query with the possibility to include sub-process tasks as well. Can you make a JIRA-issue for this, so we can schedule this accordingly?

Done.

Hi ,
I have created userTask which needs multilevel approval. when process get initiated, task id and other details are wrapped in response. But once first level1 approves(action: complete) the task a new user task gets created for level2 . let me know how to establish connection between created task for level 2 and level 1. When i marked task action as complete response is null. I am using rest API.

@Rahul and how is that related to this post?
