Ontouchmove function throws error after content is loaded

[boazbch]

Hi all,

It seems that for laptops with integrated touch screen the following problem occurs when loading content dynamically:

• "this.remove" is invoked.
• as a part of handling the memory leakage issue, the last line in this method is "self = null;".
• the next call would be of "self.ontouchmove" function.
• the first condition of this function is "if (!self.rail.drag) return true;".
• since "self" is null at this point, an exception is being thrown.

Is there an override for this issue for laptops with touch-screen? maybe an option that can be disabled?

Thanks.

When I used bind instead of delegate for this event the error had disappeared. At the moment don't know why though

By the way, error also fires in IE 10 and 11 regardless device has touchscreen or not
