[AC-2679] Issue with Facebook Login and Navigation Group

I have a navigation group that is used for login. If the user is logged in succesfully the app closes the navigation group (with navGroup.close which I assume that this is destroy the navigation group) and create a tab group. When the user logged out the tabgroup is closed and the navigation group is created again. The issue is that the facebook login button(which is on navigation group) is works fine the 1st time that the navgroup is created but the second time is execute the 'login' listener 2 times and the 3d time 3 times and so on. Here is a simplified code that generate this bug: app.js Ti.App.Properties.setString("fbAccess","login"); Ti.Facebook.appid = 'xxxxxxxxxx'; Ti.Facebook.permissions = ['publish_stream','offline_access','email']; //Ti.Facebook.forceDialogAuth = false; Ti.include('preLogin.js'); loginFBC.js Ti.Facebook.addEventListener('login', function(e) { Ti.API.info("inside login"); if ((e.success) && (Ti.App.Properties.getString("fbAccess")=="login")) { Ti.API.info("inside if"); navGroup.close(); Ti.include('preLogin.js'); }}); preLogin.js var buttonLoginFB = Titanium.UI.createButton({ top: "90%", width: "70%", height: "12%"}); var preLoginWin = Titanium.UI.createWindow({ titleImage:'/icons/logoForBar.png', title:"Back", backgroundColor:'#fff', barColor:'00aeef', }); var buttonLogin = Titanium.UI.createButton({ title: 'Login', top: "30%", width: "70%", height: "12%", opacity:1 }); var buttonRegister = Titanium.UI.createButton({ title: 'Register', top: "60%", width: "70%", height: "12%", opacity:1 }); var navGroup = Ti.UI.iPhone.createNavigationGroup({ window:preLoginWin }); preLoginWin.add(buttonLogin,buttonRegister,buttonLoginFB); var main = Ti.UI.createWindow(); main.add(navGroup); main.open(); Ti.include('/loginFBC.js'); //include the preLoginC.js that holds the code for the buttons listeners Ti.include('/preLoginC.js'); and the preLoginC.js buttonLoginFB.addEventListener("click", function(e) { Ti.API.info("button"); Ti.Facebook.logout(); Ti.Facebook.appid = 'xxxxxxxxxxx'; Ti.Facebook.permissions = ['publish_stream','offline_access','email']; //Ti.Facebook.forceDialogAuth = false; Ti.Facebook.authorize(); });
