NullPointerException encountered when creating Message Mapping

19 Views

Hi experts,

I created 3 messages using a wsdl external definition

- GetPatientDemographicOutput

- GetPatientDemographicInput

- SOAPFaultMessage

With this, I wanted to to create a message mapping object, to map GetPatientDemographicInput to a pre-defined message format.

However, when I try to select "GetPatientDemographicInput" as "Source Message" in the "Message Mapping" window, I encounter a NullPointerException.

The wsdl file I used is:
