[jboss-user] [jBPM Users] - Programmatic task execution reopens the task
My sub-process definition consists of 3 sequential task nodes: start, task 1, task2,
task3, end. At some point in the main process, I instantiate the sub-process. Later on, I
retrieve the sub-process by id and trigger execution of the first task. The task
successfully executes and
* falls down to initializeTaskVariables() of the task 2.
* commits task 1
* calls initializeTaskVariables() of task 1
* completes the token execution.
At the end of the run, the subprocess has 2 active tasks: a brand new task 1 and task 2.
Repeating the call twice, I end up with all 3 tasks being successfully processed and 3 new
tasks being created and pending in users' queue.
I observe the same problem running a much simpler case: a process definiton with 1 split,
2 tasks, 1 join. Seems that any programmatic execution of a task causes its execution
followed by immediate instantiation of the same task.
I would appreciate if you could point out what I'm doing wrong
Here's the code snippet from main process instance:
| final ProcessInstance subProcessInstance = ctx.getJbpmContext()
| .getProcessInstanceForUpdate(subprocessInstanceId);
|
| .....
|
| ExecutionContext subprocessContext = new
ExecutionContext(subProcessInstance.getRootToken());
| subProcessInstance.getRootToken().getNode().execute(subprocessContext);
|
This is debug output:
