Local fix

• Create a service flow with input and output of the same name and
   of type business object with list parameters, switch the
  undercover agent's implementation type to "service" and select
  the newly created service flow as the attached service.
  

Problem summary

• No additional information is available.
  

Problem conclusion

• A fix is available or will be available that will generate a
  correct runtime artifact when an undercover agent of variable
  implementation implemented as business object that contains a
  list parameter is saved.
  

Temporary fix
