Cannot read property "toString" from undefined

Hi David,

I have an issue with the renderOnServer, i the CommentList function
        var commentNodes = this.props.data.map(function (comment) {
            return (
                React.createElement(Comment, {author: 'comment.author'}, comment.text)
            );
        });
comment.text raise the exception : Cannot read property "toString" from undefined

Any idea ?

Thx
Bruno
