We have the following code after importing a WSDL:

```vb
Class GofilexAPI_n0

    Sub NEW
        Dim s As NotesSession
        Set s = New NotesSession
    End Sub

    Sub AuthenticationToken(password As XSD_STRING, username As XSD_STRING, AuthenticationTokenResult As XSD_STRING_HOLDER , ResultCode As XSD_INT_HOLDER)
        Print password.getValueAsString()
        Print username.getValueAsString()
        ResultCode.Value.setValueFromString("1")
        AuthenticationTokenResult.Value.setValueFromString("foobr")
    End Sub

End Class

```

We get error "Object variable not set" on trying to set values to return variables AuthenticationTokenResult and ResultCode (last two lines of the sub).
