Uncaught TypeError: Cannot read property 'show' of undefined

[kdon80]

I have ajax pages, when trying to leave the current page that has the scroll in it, it keeps throwing this message.
Before leaving the page (rewriting using ajax), I even tried destroying the scroll. It successfully destroys but somehow the following event gets called:

_showHideHotSpots: function () {

the actual error happens here when calling show().

if (o.hotSpotScrolling && o.autoScrollingMode !== "always" && el.data("autoScrollingInterval") !== null) {
    el.data("scrollingHotSpotLeft").show();
    el.data("scrollingHotSpotRight").show();

I don't understand how this if statement passes since the scroll is already destroyed...

thanks,

The issue is in the window resize binding! After destroying it, window resize is still bound!

 (window).bind("resize", function () {
            self._showHideHotSpots();

You should this in the instruction:
That when destroying the element, you might want to unbind the resize:
$(window).off("resize");
