Local fix

Problem summary

• During the copying process, the BPDExternalTaskActivityImpl was
  not set up correctly. The TeamFilter and LaneFilter refer to an
  invalid BPDActivityImpl, which has no flowObject parent. As a
  result, there is no diagram object and you receive the
  exception.
  

Problem conclusion

• A fix is available for IBM BPM V8.5.5.0 that ensures copying an
  activity that has an external implementation is done correctly
  in Process Designer.
