Element ref was specified as a string (value0) but no owner was set. You may have multiple copies of React loaded. (details: https://fb.me/react-refs-must-have-owner)

Are you asking a question?

No, just a proposal

Are you reporting a bug or runtime error?

Yes. all error just after I upgrade react to version 16.

Element ref was specified as a string (value0) but no owner was set. You may have multiple copies of React loaded. (details: https://fb.me/react-refs-must-have-owner).

My code is here:

<Select
    name="foo"
    value={this.state.input.get('foo')}
    options={fooOptions}
    placeholder="foo"
    onChange={this.metaUpdateInput('foo')}
/>

and I review this repo, notice this line may occur this error:

ref={'value' + index}

in src/Select Line 929

React 16, React-Select 1.0.0-rc.10

I finally resolved this by making an edit in my webpack setup to specifically state where to use the required version of react. Something similar to the following, with an alteration to the node modules path, will hopefully help some people:

resolve: { alias: { 'react': path.resolve(__dirname, '../../node_modules', 'react') } }
