Referring to the problem description from your link:

Now if I call loginFails() or loginSuccess(), then its showing error because its in controller Index and not in other view controller. How to solve this?

In order to reference an element inside a required view, you have to use getView('elementId').

index.xml

<Alloy>
    <Window id="fblogin" class="container">
        <Require src="loginsuccess" id="loginsuccess"></Require>
        <Require src="loginFailure" id="loginFailure"></Require>
        <Require src="loginPage" id="loginPage"></Require>
    </Window>
</Alloy>

loginsuccess.xml

<Alloy>
    <View class="container" id="successContainer" visible="false">
        <Label>Login Successful</Label>     
    </View>
</Alloy>

index.js

var successView = $.loginsuccess.getView('successContainer');

You can now perform your crossfade on successView.

Edit:
Added visible="false" to the container view
