I had >20 "Other Artifacts". When I was paging through the list in the web UI, it apparently let me page off the end of them. Subsequently the UI fails to work correctly – a message is displayed "The call failed on the server; see server log for details". The console shows this error: [webapp 2008/03/28 09:07:14] - Exception while dispatching incoming RPC call java.lang.RuntimeException: com.google.gwt.user.server.rpc.UnexpectedException: Service
