reactjs - How to use react-router 4.0 to refresh current route? not reload the whole page

'react-router-dom' has refresh function here, but I don't know how to call this method, also their well formatted document doesn't bother to explain this.

window.location.reload() doesn't work for me, because it wipes out the app store as well. I changed some data, and then need to reload the route with updated data.

I also read this: https://github.com/ReactTraining/react-router/issues/1982 https://github.com/ReactTraining/react-router/issues/2243

this thread is exactly discussing my question: https://github.com/ReactTraining/react-router/issues/4056

and still clueless how to do it. This basic function should not require too much effort, but after spending huge amount of effort, I can't reload current route.

here is my code:

@inject('store') @observer
export default class PasswordInput extends Component {
    constructor (props) {
        super(props)
        this.setPwd = this.setPwd.bind(this)
        this.submit = this.submit.bind(this)
    }

    componentWillMount() {
        this.case = this.props.store.case

        this.setState({refresh: false})
    }
    setPwd(e) {
        // console.log(e)
        this.case.pwd = e.target.value

    }
    submit() {
        console.log(this.props.caseId)
        this.setState({refresh: true})

    }

    render() {
        return (
            <Container>
                <div>{this.state.refresh}</div>
                { (this.state.refresh) && <Redirect refresh={true} to={'/cases/' + this.props.caseId}></Redirect>}
                <br />
                <Grid columns="three">
                    <Grid.Row>
                        <Grid.Column key={2}>
                            <Form>
                                <label>Enter Password</label>
                                <input placeholder="empty"  type="text" onChange={this.setPwd} value={this.case.pwd}></input>                               

                                <Button name="Save" color="green" size="mini" 
                                style={{marginTop:'1em'}}
                                onClick={this.submit}>
                                    Submit
                                </Button>                               
                            </Form>
                        </Grid.Column>
                    </Grid.Row>
                </Grid>
            </Container>
        )
    }
}

I solved this by pushing a new route into history, then replacing that route with the current route (or the route you want to refresh). This will trigger react-router to "reload" the route without refreshing the entire page.

if (routesEqual && forceRefresh) {
    router.push({ pathname: "/empty" });
    router.replace({ pathname: "/route-to-refresh" });
}

React router works by using your browser history to navigate without reloading the entire page. If you force a route into the history react router will detect this and reload the route. It is important to replace the empty route so that your back button does not take you to the empty route after you push it in.

According to react-router it looks like the react router library does not support this functionality and probably never will, so you have to force the refresh in a hacky way.
