javascript - Input data cannot be processed in the non-chronological order - Error being thrown from WinRT -


i using below code detecting gestures

var inputmanager = (function () {     var = {};     var gr;     var canvas;     var manipulating = false;       that.manipulationhandler = function (evt) {         if (evt.delta) {             //         }     };      that.ismanipulating = function () {         return manipulating;     };      that.processdown = function (evt) {         gr.processdownevent(evt.currentpoint);     };      that.processmove = function (evt) {         gr.processmoveevents(evt.intermediatepoints);     };      that.processup = function (evt) {         gr.processupevent(evt.currentpoint);     };      that.processmouse = function (evt) {         gr.processmousewheelevent(evt.currentpoint, evt.shiftkey, evt.ctrlkey);     };      // following functions registered handle gesturerecognizer gesture events     that.manipulationstartedhandler = function (evt) {         manipulating = true;         that.manipulationhandler(evt);     };      that.manipulationdeltahandler = function (evt) {         that.manipulationhandler(evt);     };      that.manipulationendhandler = function (evt) {         manipulating = false;         that.manipulationhandler(evt);     };      that.tappedhandler = function (evt) {     };      that.initialize = function () {          gr = new windows.ui.input.gesturerecognizer();          gr.gesturesettings =             windows.ui.input.gesturesettings.manipulationrotate |             windows.ui.input.gesturesettings.manipulationtranslatex |             windows.ui.input.gesturesettings.manipulationtranslatey |             windows.ui.input.gesturesettings.manipulationscale |             windows.ui.input.gesturesettings.manipulationrotateinertia |             windows.ui.input.gesturesettings.manipulationscaleinertia |             windows.ui.input.gesturesettings.manipulationtranslateinertia |             windows.ui.input.gesturesettings.tap;          // turn off ui feedback gestures (we'll still see ui feedback pointerpoints)         gr.showgesturefeedback = true;          // register event listeners gestures configured         gr.addeventlistener('manipulationstarted', that.manipulationstartedhandler);         gr.addeventlistener('manipulationupdated', that.manipulationdeltahandler);         gr.addeventlistener('manipulationcompleted', that.manipulationendhandler);         gr.addeventlistener('tapped', that.tappedhandler);          canvas = document.getelementbyid("canvas");          // register event listeners dom pointer events, these         // raw touch events using feed gesturerecognizer         canvas.addeventlistener('mspointerdown', that.processdown, false);         canvas.addeventlistener('mspointermove', that.processmove, false);         canvas.addeventlistener('mspointerup', that.processup, false);         canvas.addeventlistener('mspointercancel', that.processup, false);         canvas.addeventlistener('wheel', that.processmouse, false);     };      return that; })();

but getting error

0x80400000 - javascript runtime error: input data cannot processed in non-chronological order.

winrt information: input data cannot processed in non-chronological order.

thrown in processmove function when tapped away crazy on device. device using multi touch tablet. adding try catch blocks around each of functions seemed fix it. 

that.processdown = function (evt) {         try {              gr.processdownevent(evt.currentpoint);         } catch (e) { }     };      that.processmove = function (evt) {          try {             gr.processmoveevents(evt.intermediatepoints);          } catch (e) { }     };      that.processup = function (evt) {         try {             gr.processupevent(evt.currentpoint);         } catch (e) { }     };

is correct/best approach detecting gestures on multi touch device , handling error been thrown?
