Error description

  • When an update is performed using a Uint64 value ( which is
    only possible using the C# .NET support ), an FFDC exception
    occurs that contains the text "XFError: XDF Error: Fields
    still need serializers".
    The update performs successfully, but the logic that merges
    the previous version of the data with the new value as part of
    the XDF class evoluion support will not be performed.  This
    will mean that all fields that do not exist in the current
    value's version are lost.  If you only have one version of the
    value class that contains the Uint64, then this FFDC message
    can be ignored.

    * RECOMMENDATION:                                              *
    ****************************************************************
    An eXtreme data format (XDF) serializer was added for C#
    unsigned
    64-bit integers (Uint64).
    

Problem conclusion

  • XDF now correctly serializes and deserializes C# unsigned
    64-bit integer (Uint64) and FFDC messages not generated.
