React-starter-kit: How to call child's method or child's refs?

[joonhocho]

I want to call child method or reference to child's refs.
It should work, but refs.child returns ProxyComponent rather than Child. And, the ProxyComponent does not have method nor refs.root.
I think this is due to having hot module reloading together with withStyles.
Any ideas? I've tried with release mode as well, but to no avail.

Child.js

import React, {PropTypes} from 'react';
import withStyles from 'isomorphic-style-loader/lib/withStyles';
import s from './Child.css';


class Child extends React.Component {
  method() { console.log('child'); }

  render() {
    return (
      <div ref="root">
      </div>
    );
  }
}

export default withStyles(s)(Child);

Parent.js

import React, {PropTypes} from 'react';
import withStyles from 'isomorphic-style-loader/lib/withStyles';
import s from './Parent.css';
import Child from './Child';


class Parent extends React.Component {
  callChildMethod() { this.refs.child.method(); } // doesnt work.

  render() {
    return (
      <div>
        <Child ref="child" />
      </div>
    );
  }
}

export default withStyles(s)(Parent);

Like so?

@frenzzy I've tried the suggestion, but it didnt work. It also returned the proxy component.

Please explore the demo more carefully: https://jsfiddle.net/frenzzy/z9c46qtv/3/

@frenzzy The demo doesn't really help because I think it's problem caused by hot module reloading.

This approach works fine with hot reload in master branch.
Maybe you want to use this and just forgot to bind context?

P.S.: Added a tiny new section to React docs: When to Use Refs

@joonhocho Did you resolve it?
I think it is no RSK issue → closing.
Feel free to reopen if you need more help.

You have to call the function callChildMethod() of your parent component from inside render function.

That's a horrible hack, sorry
