APAR status

• Closed as program error.

Error description

• Attempt to set nillable="true" for a complex element in a DFDL
  schema gives CTDV1464E error.
  

Local fix

• NA
  

Problem summary

• ****************************************************************
  USERS AFFECTED:
  All users of IBM Integration Bus V10.0 who attempt to set
  nillable="true" for a complex element in a DFDL schema.
  
  
  Platforms affected:
  MultiPlatform
  
  ****************************************************************
  PROBLEM DESCRIPTION:
  An attempt to set nillable="true" for a complex element in a
  DFDL schema gives a CTDV1464E error.  Users may want to do this
  to preserve the positions of occurrences in a sparse array. This
  was a documented restriction, which has now been removed.
  
  
  There are a number of resource name changes between WebSphere
  Message Broker and IBM Integration Bus Version 9.0.  For details

Problem conclusion

• The DFDL editor in the IIB Toolkit now displays the nillable
  property for complex elements in edit mode. If set to "true",
  the DFDL properties nilKind, nilValue and
  nilValueDelimiterPolicy are also displayed. DFDL property
  useNilForDefault is not displayed as this is for simple elements
  only. Property nilKind must be "literalValue" and nilValue must
  be "%ES;".
  
  The DFDL parser now checks if a complex element can be nil. If
  so then it looks for the nil value of %ES; in accordance with
  section 9 of the DFDL specification, including checking that the
  nilValueDelimiterPolicy is obeyed. If the element is nil, an
  element value event occurs with special value "nil".
  
  The DFDL serializer now allows an element value event for a
  complex element, but the value must be the special value "nil".
  If such an event is received, no events are expected for child
  elements. As the nil value is %ES; nothing is output to the data
  stream, and the nilValueDelimiterPolicy is obeyed.
  
  The restriction documented in the Knowledge Center,
  https://www.ibm.com/support/knowledgecenter/SSMKHH_10.0.0/com.ib
  m.etools.mft.doc/df00150_.htm, has now been removed.
