Getting a warning accessing findDOMNode inside render

[sakin]

Warning: {COMPONENT} is accessing findDOMNode inside its render(). render() should be a pure function of props and state. It should never access something that requires stale data from the previous render, such as refs. Move this logic to componentDidMount and componentDidUpdate instead.

I could be doing it wrong, my ref looks like this:
<tr ref={row => { this.row = row; }} >

that looks correct... where are you calling findDOMNode?

this is coming from here i think.
So if you call scrollToComponent inside your render you will get this warning.

For me the following code made this error:
ReactDOM.findDOMNode(this.refs.textInput).focus();

I fixed the issue with this:
this.refs.textInput.focus();

My code looks like this:

constructor(props) { super(props); this.textInput = null; }
render() { return <input ref="textInput" />; }
