I am trying to follow the step-by-step instruction from Franklin Herbas's blog - https://www.sdn.sap.com/irj/sdn/weblogs?blog=/pub/wlg/8018. [original link is broken] [original link is broken] [original link is broken] It worked fine initially but I ran into problem when double-clicked on the small round icon on left-bottom side of the operation in the model, a window did pop up confirming creating object for the operation. But when I clicked on Create, nothing happened. No operation is created in the service interface. I have checked and there is no error in the Java log.
Any idea what I may have done wrong? I am running on ESR 7.1 SP4 on CE 7.1 SP4.
