RangeSlider and Grid cause null pointer exception

[azurek]

Hi, We use rangeslider together with the grid.

Pagination is turned on for the grid and we noticed that sometimes when user changes pages they witness null pointer exception. We tracked it down to dispatchDragAndDrop function where payload is null.

By introducing null checking around payload we resolved the error. Please see below and disregard console messages as they were just internal testing.

This seems to be caused by rerendering and i have noticed that you already have a failsafe for that where if you detect scroll you exit the function without even using payload, however this failsafe exists below code which extracts payload and raises exception because it was null.
