I have created decision graph template and an instance for the same. I tired executing it by calling instance name using apply keyword. Instance has to return String value. But While executing the same, I received <Unavailable> return value. I am not sure whether I run it in correct way. It would be helpful, if anyone says how to run decision graph in Blaze Advisor IDE.
tripApp.carType = apply CarType_Decision_Graph_Template_Instance.
