Check the render method of Text. See http://fb.me/react-warning-keys for more information.\r\n```\r\n\r\nAfter some searching I ended up in `react.js`, where I found (in `ReactElement.createElement`):\r\n\r\n```\r\nkey = config.code === undefined ? null : '' + config.code;\r\n```\r\n\r\nI finally managed to get rid of the warning by using `React.createElement(\"li\", {code: ...})` instead of `React.createElement(\"li\", {key: ...})`.\r\n\r\nThis should be fixed, probably in `.createElement`, or at least in the docs/warning."}}
