multiple import for one files to scene, not working!

[phproot]

A.js

....
export default connect( .... )(A)

B.js

....
export default connect( .... )(B)

C.js

....
export default connect( .... )(C)

Scene.js

...
import { A, B, C } from './Page';
...
<Scene key='a' component={A} ...>
<Scene key='b' component={B} ...>
<Scene key='c' component={C} ...>

Error : Component property is not set for key=A or B or C
When such a reference, an error occurs. Supports multiple import manner?

Page.js

import A from '../controllers/initial/A.Controller';
import B from '../controllers/initial/B.Controller';
import C from '../controllers/guest/C.Controller';



export {
    A,
    B,
    C
};

connected component.
