of-flow: sal-flow:update-flow return 400

odl:
org.opendaylight.controller.version = 0.1
org.opendaylight.controller.build.scm.version = 15e9db7d90e46f014aeba760263623094bc48f14
org.opendaylight.controller.build.user = jenkins-controller
org.opendaylight.controller.build.workspace = **********
org.opendaylight.controller.build.timestamp = 1410248111419
org.opendaylight.controller.build.machine = **********

when trying to use /restconf/operations/sal-flow:update-flow i get 400, the same xml works for add-flow, so the problem should be somewhere else.
