APAR status

  • Closed as program error.

Error description

  • A CTDU4132E error is seen when serializing a message when an
    empty string value is used with a numeric field. In previous
    versions of the code some numeric types such as int or long
    would not result in the error for empty string values but would
    instead return a 0 value. This APAR reverts the code to the
    previous case when the DFDL feature is set

Problem summary

  • ****************************************************************
    USERS AFFECTED:
    Users of IBM Integration Bus v10 and App Connect Enterprise v11
     who use the DFDL serializer to serialize messages that contain
    elements that have been set to "" by nodes in a flow.
    
    
    Platforms affected:
    z/OS, MultiPlatform
    
    ****************************************************************
    PROBLEM DESCRIPTION:
    In previous versions of IIB the DFDL code would allow elements
    with numeric types to have "" as a value. This would then be
    converted to a zero value when serialising. Stricter type
    checking was introduced in the DFDL code which would not accept
    the "" value as it was a string instead of a number. IIB flows
    that were migrated from the older version would then stop
    working.
    

Problem conclusion

  • An environment variable,
    "MQSI_DFDL_SERIALIZE_EMPTY_STRINGS_IN_NUMERICS" was added that
    would cause the DFDL code to behave as in previous versions and
    accept "" as a value for numerically typed fields, converting
    them to a zero value.
