JR63863: CONSUMING AN EXPOSED WEB SERVICE MIGHT RESULT IN A TYPE MISMATCH ERROR AT RUN TIME

APAR status

• Closed as program error.

Error description

• You may encounter an issue in the following scenario:
  
  You exposed a web service, and that web service is implemented
  using a service flow. The service flow has a list parameter
  typed by a business object with advanced property "Namespace"
  set to "<default>". The business object is contained in a
  workflow automation, process app or toolkit that does not define
  a namespace itself.
  
  You consume this exposed web service as external service. At run
  time, a type mismatch error occurs.
  
  For example, the "NameValuePair" business object of the "System
  Data" toolkit has the "Namespace" advanced property set to
  "<default>" and the "System Data" toolkit does not define a
  namespace in the process app or toolkit settings. Therefore, if
  you use the "NameValuePair" business object as a parameter for a
  service flow that is used by a web service, and you discover
  that web service the resulting external service has a wrong
  interface. At run time, a type mismatch error occurs:
  TeamWorksException: Type mismatch. Expected
  "tw.object.ArrayOf_NameValuePair[]" type, but found
  "tw.object.NameValuePair[]"
