Local fix

Problem summary

• When a coach fires a boundary event, the data is sent to the
  server and processing the other steps, for example server
  scripts or service invocations, continues.
  If the navigation reaches the same coach or a Stay on page
  event, the server sends the data that was changed on the server
  back to the browser only. In this delta-comparison, a list
  property set to null was not correctly handled, causing the
  ClassCastException.
