I have installed last version of Opendaylight (karaf-0.17.2) and I have launched karaf. When I send GET requests to ODL, everything is fine (Ex : "http://<MY_ODL_IP>:8181/rests/data/opendaylight-inventory:nodes/node=openflow:108841855832911?content=nonconfig ==> OK) But when I try to add a flow rule with a PUT request I get "409 Conflict" response. Here is an example : URL : http://<MY_ODL_IP>:8181/rests/data/opendaylight-inventory:nodes/node=openflow:108841855832911/table=0/flow=0
