Can't get showLoginScreen to work

Hi,

I’ve been trying to get auth.showLoginScreen to work. All I get is a blank screen when I run the code. I’ve broken my code down to its barest essentials, shown below. Any advice on how to get this to work would be appreciated.

var app = require('app');
app.init();

var authObj = require('auth').Auth;
 
var auth = new authObj();
if (auth.isLoggedIn()) {
    return auth.showLoginScreen();
}

I got this one to work. The log viewer wasn’t working on my browser. So I was flying blind. Once I switched to a new PC the log viewer started to work and I was able to debug the code. See below.

[code]var app = require(‘app’);
app.init();

var Language = require(‘localization_language’).Language;

var lang = new Language({‘langLocale’ : ‘en_us’});

var authObj = require(‘auth’).Auth;

var auth = new authObj({

'lang' : lang

});
auth.logout({
‘callback’ : callbackFunction,
});
auth.showLoginScreen({
‘callback’ : callbackFunction,
});

function callbackFunction (){};[/code]
