Here's my code:

        case 2:
            if (Titanium.Facebook.isLoggedIn()==false)
            {
                Titanium.Facebook.LoginButton.fireEvent('click', fbButton);
                //fbButton.fireEvent('click');
                //Ti.UI.createAlertDialog({title:'Facebook', message:'Login before uploading your photo'}).show();
                //return;

            }
            else{
                if (!Titanium.Facebook.hasPermission("photo_upload"))
                {
                    Titanium.Facebook.requestPermission("photo_upload",function(evt)
                    {
                    if (evt.success)
                    {
                        uploadPhoto();
                    }
                });
                }
                else
                {
                    uploadPhoto();
                }            
            }

I've trying to trigger the facebook login window through a button in an options dialog. Is this even possible?
