Comment 4 for bug 1242947

from the heat-api server:

2013-10-29 15:58:14.308 ERROR root [-] Returning 404 to user: The resource could not be found.
2013-10-29 15:58:14.309 DEBUG root [-] JSON response : {"explanation": "No event 11 found", "code": 404, "error": {"message": "No event 11 found", "traceback": " File \"/home/asalkeld/work/heat/heat/common/wsgi.py\", line 661, in __call__\n request, **action_args)\n File \"/home/asalkeld/work/heat/heat/common/wsgi.py\", line 729, in dispatch\n return method(*args, **kwargs)\n File \"/home/asalkeld/work/heat/heat/api/openstack/v1/util.py\", line 30, in handle_stack_method\n return handler(controller, req, **kwargs)\n File \"/home/asalkeld/work/heat/heat/api/openstack/v1/util.py\", line 46, in handle_stack_method\n return handler(controller, req, dict(stack_identity), **kwargs)\n File \"/home/asalkeld/work/heat/heat/api/openstack/v1/events.py\", line 121, in show\n raise exc.HTTPNotFound(_('No event %s found') % event_id)\n", "type": "HTTPNotFound"}, "title": "Not Found"} from (pid=18232) to_json /home/asalkeld/work/heat/heat/common/wsgi.py:562

seems to be returning the correct thing.
I'll move the bug to python-heatclient
