Version 7.5.1 Fix Pack 1 for the IBM Business Process Manager products

APAR status

• Closed as program error.

Error description

• Outbound web service integrations may expect a response
  containing optional response elements.  Response elements are
  defined as optional in the WSDL by setting the attribute
  "minOccurs=0" on the element.
  If an outbound web service integration expects a response with
  optional elements, and those elements are not present in the
  response, an  exception similar to the following will be seen:
  com.lombardisoftware.core.TeamWorksException: CWLLG1128E:
  Deserialization Error, Unable to fetch parameter from the soap
  envelope. at

  Outbound web service integrations may expect a response
  containing optional response elements.  Response elements are
  defined as optional in the WSDL by setting the attribute
  "minOccurs=0" on the element.
  If an outbound web service integration expects a response with
  optional elements, and those elements are not present in the
  response, an exception similar to the following will be seen
  but will not prevent the response from being processed normally:
  com.lombardisoftware.core.TeamWorksException: CWLLG1128E:
  Deserialization Error, Unable to fetch parameter from the soap
  envelope. at
  com.lombardisoftware.core.TeamWorksException.asTeamWorksExceptio
  n(TeamWorksException.java:136) at
  com.lombardisoftware.core.RegexExceptionRewriter.rewrite(RegexEx
  ceptionRewriter.java:76)
  If an empty response is expected, the CWLLG1128E message can be
  ignored.
  

Problem conclusion

• Code changes have been made to handle the optional elements
  properly.  The fix will be available in fix pack v7.5.1.1 and
  v8.0.1.0.
