If any of the filters has null values in the data, processFilters method getting failed.
in pivot_unminified.js (v 4.3.0, line # 342)
I need to change this line from
for (var s in r) o = r[s][e], webix.isUndefined(o) || a[o] || (n.push({
to
for (var s in r) o = r[s][e] !== null? r[s][e] :"", webix.isUndefined(o) || a[o] || (n.push({
to make it work.
Is there any way I can override this method?
