How to access the processExecutionID of the currently created process.

[imthiaz_d]

Hi,

I am new to BPMN modeling and Activiti. I started working on it. I learnt to create a process by a post call

"runtime/process-instances" and passing the Process definition key to it.

I am able to mark the Tasks using "runtime/tasks/" + taskId" post call.

I am trying to implement an product ordering, manufacturing and delivering process. Lets call it order management system.

I want to map each order to the instance of the process created for it.

I am trying to set the variable order with the order ID while creating the process itself. like below

Map<String, Object> v =new HashMap<String, Object>();
v.add("orderID",orderId);

and passing the map to the post call like below

/runtime/tasks/" + taskId, pojo)

But thats not setting the process variable.

The other way is, I can set the process Execution Id on the order object and then I can map the process to the order object.

The problem is, I don't know how to access the processExecutionId of the currently created process.

It would be very help if the answer has some samples in it.

Thank you for the Help.

Imthiaz,

I'm not sure, based on your comments whether you're doing all of this in Java or Javascript - can you give a little more detail on where you're trying to do this? Is it in Java or Javascript, or potentially all over REST?

At a brief level:
If you're doing this in Java, there is something called a RuntimeService, that has several methods to start processes. Each of these methods has an overloaded version that allows for a parameter that contains the variable utilized within the process. This blog post has a couple utilization examples of the RuntimeService.

If you're doing this in Javascript over REST, since you have access to the 'TaskId', you should be able to perform a GET /tasks/{taskId} which will include the executionId if it has been set by that time.

If you're doing this in the Javascript (Angular) of Activiti, these values exist inside the $scope variable - particularly $scope.task will contain the data you're looking for, depending on your location inside the app.

Hope this is a start, but I can help more with a little bit more context,
