We are using common app and transformer approach to implement translib support for a openconfig module. For replace operation we are seeing an issue. Consider following test objects ======================= container A { container B { list C { key id; leaf id { type uint; } } } } Current DB content ============== A/B/C/1 A/B/C/2 Two instance of object C exists in DB. Request Payload for PUT operations =========================== url = /A/B url_body = { B { C [{ 1, {}}, {3, {}}] } So, We are trying to replace object /A/B with two instances of C (1 & 3) Expectation ========= As requested payload as only instance 1 & 3 And DB has instance 1 & 2 So, framework should **delete instance 2**, **keep instance 1** as it is and **Create instance 3**. Current Behaviour ============= Instance 1 is kept as it is (Expected) Instance 3 is Created. (Expected) **Instance 2 is not deleted (Not expected)** Observation ========= From the processReplace code, looks like currently only dbMapCreate is handled for Replace operation, IMO dbMapDelete should also be handled here
