const ApplicationSource = {
 withdrawApplication: {
    remote (state, application) {
      return $.ajax({url: 'somepath', method: 'GET'});
    },
    success: applicationActions.withdrawApplicationSuccess,
    error: applicationActions.withdrawApplicationFailure,
  }
}

Whenever /somepath returns a 200 it is handled by the success handler 'withdrawApplicationSuccess' but a non-200 (for ex 500 or 404), is not handled by error handler 'withdrawApplicationFailure'.

Note We are using jquery 1.11. So I am assuming the $.ajax returns a Promise.

Is there anything wrong with this?
