Main process definition

Description of problem:

We execute a flow with subprocesses as you can see in the attached file "proc_encendido_v1.bpmn2". When the execution process arrives to "Subproceso de encendido de dispositivo", it receives a list of "dispositivos" and by using each element of the list, it triggers a process. At the end of the execution we can see that in PROCESSINSTANCELOG table the subprocesses info appears twice. Moreover you can see duplicated process instances in the Process Instances list in the business-central.

Version-Release number of selected component (if applicable):

EAP 6.4.5 + BPMS 6.2 + PostgreSQL

How reproducible:

You must log on the business-central and create an empty project although you can use the default project created the first time you installed BPMS. Then you can import the processes attached to this ticket "proc_encendido_v1.bpmn2" and "task_encender_v1.bpmn2" and deploy the project as "PER_PROCESS_INSTANCE" strategy. Finally you can start the process from a java code using REST API.

Steps to Reproduce:
1. Install EAP 6.4.5 + BPMS 6.2 + PostgreSQL
2. Create a user "bpmsAdmin" with roles: admin,analyst,rest-all
3. Log on the business-central.
4. Create an empty project or use the default project created the first time you installed BPMS.
5. Import the processes attached to this ticket "proc_encendido_v1.bpmn2" and "task_encender_v1.bpmn2".
6. Deploy the project as "PER_PROCESS_INSTANCE" strategy.
7. Start the process from a java code as following:

    } catch (Throwable e) {
      e.printStackTrace();
      results = "KOOOOOOOO";
    }

    return results;
  }
	
}
~~~

Actual results:

21 instances in PROCESSINSTANCELOG table where the subprocesses info appears twice. 
21 process instances in the Process Instances list in the business-central with duplicated process instances. 

Expected results:

11 instances in PROCESSINSTANCELOG table. 
11 process instances in the Process Instances list in the business-central.
