Hello, I am using callback in my use-case, the scenario is that the callback should happen (to the client) only after the approval from an approver. As I could see from the samples that the flow is streamlined, I had tried out a sample separating the service & client as different composites but it is not working as it is throwing some NullPointer Exception while invocation, I would be grateful if anyone would like to help me in this regard.
Thanks & Regards, Ashwini Kumar J
