PK08829: WHEN INVOKING A WEB SERVICE THAT WILL RETURN NESTED VARIABLE ARRAYS, THE ARRAYS ARE RETURNED IN REVERSE ORDER.

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• Contents of the 'variable repeat' element get reversed on
  return from CICS.
  A web service is invoked that will return nested variable
  arrays. It has been set up to return 3 instances of the
  original string, sent as 1,2,3 concatenated to the end of the
  original string.
  
  But the service always returns the repeat array in 3,2,1 order.

  A SOAP message is being parsed by DFHPICC to produce a commarea
  from the incoming XML.  The XML contains a variable repeat
  element (i.e. a variable length array).  This will be passed to
  the target application in a container.
  
  The individual elements that make up the array are processed in
  turn by adding them to the head of the list.  When the container
  is built the list is processed starting at the head and each
  item is added to the container in order.  This has the effect of
  the data in the container being in the reverse order of what was
  sent in the XML.
  
  This problem occurs for requests being received by a service
  provider and for responses received by a service requester.
  

Problem conclusion

• DFHPICC has been altered so that the data in the container
  created for a variable repeat element is in the same order as
  the data in the incoming XML.
