Facebook login button and Navigation group

You must Login before you can answer or comment on any questions.

So I have a a preLogin.js which is create a navigation group. After login I put navGroup.close() and the navigation group is closed. If the user is logged out I include the preLogin.js and the nav group is created again. Everything was working fine until I enter this in preLogin.js:

var buttonLoginFB = Titanium.Facebook.createLoginButton({
         top: "90%",
         width: "70%",
         height: "12%",
        });
The navGroup is closing as before but when is create for the second time, if the user press the facebook login button the fb login listener is executed 2 times. If I log out again and I press fb login button is executed 3 times and so on. So, why the fb login button does not work as the other buttons? Why it remains there and is executed 2 or 3 times?

  • More details please? It sounds like you are adding the listener to the facebook button multiple times, or adding the facebook button multiple times.

  • it's the facebook button that it added several times.here is the prelogin.js

    var buttonLoginFB = Titanium.Facebook.createLoginButton({
         top: "90%",
         width: "70%",
         height: "12%",         
        });
 
 
 
var preLoginWin = Titanium.UI.createWindow({  
        titleImage:'/icons/logoForBar.png',     
        title:"Back",
        backgroundColor:'#fff',
        barColor:'00aeef',
       });
 
other buttons....
 
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('/code/loginFBC.js');
    here is the loginFBC.js:
    Ti.Facebook.addEventListener('login', function(e) {
 
 
      if (e.success) {
 
    some xhr.reguest
 
    xhr.onload = function(){
 
                    main.remove(navGroup);
                     navGroup.close();
 
                      //recreate the tabgroup
                 Ti.include('/view/tabGroup.js');
 
 
}
    and this is the logout.js
    some xhr request
 
if (reply="LOGOUT"){
 
 
                    tabGroup.close();
                    Ti.include('/view/preLogin.js');
 
 
                }
