Basic usage failing

[msimonc]

Thanks for this project!

When I wrap a tag in an otherwise working render() function:

import { Collapse } from 'react-collapse';
...
return (
                <Collapse isOpened={true}>
                    <h3>Cars</h3>
                </Collapse>
            );

I get:
Warning: React.createElement: type should not be null, undefined, boolean, or number. It should be a string (for DOM elements) or a ReactClass (for composite components).

Dependencies installed, Babel 6 / ES6, webpack build...

import Collapse from 'react-collapse';

react-collapse exports only one component.

Thanks, but I now get:

Error: Invariant Violation: addComponentAsRefTo(...): Only a ReactOwner can have refs. You might be adding a ref to a component that was not created inside a component's render method, or you have multiple copies of React loaded (details: https://fb.me/react-refs-must-have-owner).

[nkbt]

Are you adding ref anywhere? To <Collapse> for example? That would not work I believe.

Can you clone http://codepen.io/nkbt/pen/MarzEg?editors=101 and put your example there to reproduce the issue?

I am also having this error with latest version of react. Using as follows:

<Collapse isOpened={this.state.expanded}>{this.props.children}</Collapse>

[nkbt]

@calvinfroedge which version of React you are using?
http://codepen.io/nkbt/pen/MarzEg?editors=101 -- this demo works pretty well with react@0.14.6

I reckon I can close this now...
