Doesn't work with Navigator

It seems not to work with navigator as tab item.

```
getTabView() {
switch (this.state.page) {
case 'Home':
return
break;
case 'Drafts':
return
break;
case 'Tasks':
return
break;
}
}

render() {
return (

{this.getTabView()}



Home



Drafts



Tasks



);
}
```

In this if I change my view as any other view instead of HomeNavigator, it works perfectly. But not with a navigator component which is original navigator. However the same HomeNavigator works well if not inside tabs.

Can anyone help please?
