  ****************************************************************
  A process containing user defined Business
  Objects is install and an instance
  started.  Subsequently, the process is
  updated such that parameters are removed
  from a Business Object, and a new snapshot
  is taken.  Upon installing the new
  snapshot on the process server, the
  "Migrate" option is selected for the
  currently running process.  The Migration
  succeeds but REST APIs such as
  http://localhost:9081/rest/bpm/wle/v1/proces
  s/<piid>?parts=all, will fail with a
  CWTBG0019E error response.  The
  SystemOut.log will show a stack trace
  similar to the following:
  [2/7/13 13:25:24:384 CST] 00000090 wle
  E   CWLLG2015E:  An unexpected
  runtime exception occurred. See exception

Problem conclusion

• The REST API runtime has been corrected to ignore missing
  parameters on Business Objects instead of throwing an
  exception. The fix will be available on v7.5.1.0 and included
  into the next fixpack.
