Application type: mobile Titanium SDK: 3.3.0GA Platform & version: iOS 7.1 Device: iOS simulator Host Operating System: OSX 10.9.5 Titanium Studio: 3.2.3.201404181442 a simple test case:

it working first but after changing direction one more times it stops and not working specially in rtl direction

// this function will open left slider
Alloy.Globals.openLeftMenu = function() {
    //console.log('menu '+isSliderOpen);
    var newWidth = Ti.Platform.displayCaps.platformWidth;
    if (OS_ANDROID)
        newWidth /= Ti.Platform.displayCaps.logicalDensityFactor;
    $.AppWrapper.width = newWidth;
 
 
    if (isSliderOpen) {
 
        closeMenu();
 
    } else {
 
        openMenu();
 
    }
 
};
 
function openMenu() {
 
 
    console.log("Alloy.Globals.langProp.direction "+Alloy.Globals.langProp.direction );
     if (Alloy.Globals.langProp.direction == "ltr") {
 
        $.SlideMenu.Wrapper.animate(animate_left_reset);
        $.AppWrapper.animate(animate_left);
 
    } else {
 
      $.SlideMenu.Wrapper.animate(animate_right_reset); 
     $.AppWrapper.animate(animate_right);
 
    } 
 
    // set slider is open isSliderOpen as true
    isSliderOpen = true;
}
 
function closeMenu() {
 
    console.log("Alloy.Globals.langProp.direction "+Alloy.Globals.langProp.direction );
     if (Alloy.Globals.langProp.direction == "ltr") {
        $.AppWrapper.animate(animate_left_reset);
        $.SlideMenu.Wrapper.animate(animate_left_minus); 
 
    } else {
        $.AppWrapper.animate(animate_right_reset);
        $.SlideMenu.Wrapper.animate(animate_right_minus); 
 
    } 
 
    //console.log(Ti.Platform.displayCaps.platformWidth + " : "+$.AppWrapper.width);
    // set slider is close isSliderOpen as false
    isSliderOpen = false;
}
 
 
var animate_left_reset = Ti.UI.createAnimation({
            left : 0,
            duration : 200,
            curve : Ti.UI.ANIMATION_CURVE_EASE_IN_OUT
        });
  var animate_left = Ti.UI.createAnimation({
            left :280,
            duration : 200,
            curve : Ti.UI.ANIMATION_CURVE_EASE_IN_OUT
        });
var animate_left_minus = Ti.UI.createAnimation({
            left :-280,
            duration : 200,
            curve : Ti.UI.ANIMATION_CURVE_EASE_IN_OUT
        }); 
 
 var animate_right_reset = Ti.UI.createAnimation({
            right : 0,
            duration : 200,
            curve : Ti.UI.ANIMATION_CURVE_EASE_IN_OUT
        });
 var animate_right = Ti.UI.createAnimation({
            right :280,
            duration : 200,
            curve : Ti.UI.ANIMATION_CURVE_EASE_IN_OUT
        });
var animate_right_minus = Ti.UI.createAnimation({
            right :-280,
            duration : 200,
            curve : Ti.UI.ANIMATION_CURVE_EASE_IN_OUT
        });
