Getting this with RC1 too, and also getting invalid proptypes for children:

static propTypes = {
  children: React.PropTypes.node.isRequired
}

When passing down JSX nodes we get this error:

Warning: Failed propType: Invalid prop ​`children`​ supplied to ​`Card`​, expected a ReactNode. Check the render method of ​`ContainerStatus`​.

Might this be because of the same checking? If not will open a separate issue.

@tonyhb no that would be unrelated. Can you file a new issue with code to reproduce.

[tonyhb]

Will do.

I'm having this problem using this lib (https://github.com/davidguttman/react-pivot/blob/master/index.jsx) as well. any thoughts?

[luisrudge]

@spicyj thoughts on this one?

[sophiebits]

@luisrudge Guessing react-pivot has its own copy of React. Try rm -rf node_modules/react-pivot/node_modules/react/.

[luisrudge]

I'm using npm3, so it's all flattened

Need to investigate how IE9 and IE10 behaves with these static properties. For anyone in this thread who's not on IE and not using scala-js, please file separate issues with repro steps.
