How to retrieve ref to input when HOC used
See original GitHub issueWhen defining an input class as lower order component of Formsy, how does one go about retrieving a ref to the underlying input component?
If an input class is simply:
class Input {
render() {
return (<div><label ...props>{this.props.caption}</label><input ...props/></div>);
}
export default Formsy.HOC(Input);
And the form:
class AForm {
componentWillReceiveProps() {
// How to access the input component? this.refs.input refers to the HOC of Input.
}
render() {
return (
<Form>
<Input ref="input" ...props/>
</Form>
);
}
}
Say I would like the Input class to allow for the focus to be set programmatically on its {input,textarea} element; how would I go about doing so? How would such an interface be exposed from Input
above?

The HOC passes all props through to the component it is wrapping, so you can simply use a callback ref to achieve your goal.
