Problem summary

• ****************************************************************
  * USERS AFFECTED:  BPM REST API users.                         *
  ****************************************************************
  * PROBLEM DESCRIPTION: Property "step" is not returned when    *
  *                      the current step is in a subprocess.    *
  ****************************************************************
  * RECOMMENDATION:                                              *
  ****************************************************************
  Property "step" is returned by examining the current workflow
  step and matching it with the process items in the service
  model. The root cause of the problem was the correct "step"
  could not be found when it is inside a subprocess.
  The problem can be reproduced by using the REST API
  Tester application, it is available at:
  http://<bpm server>:9080/bpmrest-ui/
  Steps to reproduce:
  1) Start a process instance in the Process Designer and
  look for the task id.
  2) Go to the REST API Tester application and navigate to
  WLE REST APIs -> Service API -> Resume Service. In the "Service
  Instance ID:" field, use the task id from the previous step and
  in the "Button or Endpoint:" field use the button or endpoint
  on the coach.
  3) Click Execute Call and it should show the return result.
  4) Review the response, the property "step" is missing.
  

Problem conclusion

• New logic was added to look inside the subprocess to find the
  correct step.
