Use a static property named `defaultProps` instead.\r\n- **Warning**: Something is calling a React component directly. Use a factory or JSX instead. See: http://fb.me/react-legacyfactory\r\n- **Warning**: RaisedButton(...): No `render` method found on the returned component instance: you may have forgotten to define `render` in your component or you may have accidentally tried to render an element whose type is a function that isn't a React component.\r\n- **Warning**: Don't set the props property of the component. Mutate the existing props object instead.\r\n- **TypeError**: Can't add property context, object is not extensible\r\n\r\nIs material-ui dependent on a specific version of React? I am using the latest stable version."}}
