Congratulation for the great work on react_on_rails! 👍

I have just started trying it out. I am facing an issue where I cannot access the railsContext in the constructors of my components. It is always an empty Object {}.

Tracking down the stack brings me to node_package/src/createReactElement.js, because my component is a react component and not a generator function that returns one, it uses React.createElement(component, props) thus, discarding the railsContext.

export default class NavigationBar extends React.Component {

  constructor(props, _railsContext) {
    super(props)

    console.log(_railsContext) // Object {}
  }
  ...
}
import ReactOnRails from 'react-on-rails'
import NavigationBar from '../containers/navigation-bar'

ReactOnRails.register({
  NavigationBar
})
  <body>
    <%= react_component 'NavigationBar' %>
    ...
  </body>

What am I doing wrong ?

Hi @othierry, the docs specify your answer. You need to use a generator function.
