CA Gen 8.6 Toolset add Call External statement crashes with 0xc0000005 in IEFAD.dll
Support confirmed similar behaviour with the customer's file. The Toolset identifies the operation inside the WSDL file but after selecting it and using the Add button the Toolset crashes. Windows Event Viewer shows similar exceptions:

Cause

The crash is occurring because the wsdl file has no "wsdl:output" operation.
The concept of a one-way operation (either only request or response or fault) is not supported in the original Call External design.
It was designed that way because in the SOAP world the HTTP POST verb is used which requires Call External to send the request to the server and receive some response.
It was always assumed that both "wsdl:input" and "wsdl:output" would be present in the WSDL and for a Gen user the flexibility of what data to use is provided in terms of the optional mapping.

Environment

Release : 8.6

Component : CA Gen Workstation Toolset

Resolution

Simply by duplicating the existing "wsdl:input" in the "wsdl:operation" section of the file to add the new "wsdl:output", stops the crash from occurring i.e.

Change:
    <wsdl:operation name="...">
      <wsdl:documentation/>
      <wsp:Policy>
        <wsp:PolicyReference URI="..."/>
      </wsp:Policy>
      <wsdl:input message="p1:xmln...."/>
    </wsdl:operation>

To:
    <wsdl:operation name="...">
      <wsdl:documentation/>
      <wsp:Policy>
        <wsp:PolicyReference URI="..."/>
      </wsp:Policy>
      <wsdl:input message="p1:xmln...."/>
      <wsdl:output message="p1:xmln...."/>
    </wsdl:operation>
 

Additional Information

The fact that a crash occurs for this scenario rather than it being handled more gracefully is something Gen Engineering will look into changing as a backlog defect.
