Error description

  • If a coach view contains many service calls, and those service
    calls run concurrently, the following NullPointerExceptions
    might occur:
    java.lang.NullPointerException

    to coach view fields being not set.

Local fix

Problem summary

  • After a business object is loaded from the database, it is
    activated. Before this activation is complete, the business
    object is already used in concurrent service calls. As a result,
    exceptions occur.
    

Problem conclusion

  • A fix is available for IBM BPM V.8.0.1.2 that prevents the use
    of a business object before its activation is complete.
