Filtering issue - Unable to get property 'push' of undefined or null reference


I am using igHierarchical grid using Load on Demand and row level editing.

I am using Simple Filtering feature which works fine the first time the grid is loaded. However if I make a change to the row and click on done I am not able to use this feature and it throws the following error:

Unhandled exception at line 23, column 15086 in localhost:31607/.../infragistics.ui.editors.js

0x800a138f - JavaScript runtime error: Unable to get property 'push' of undefined or null reference

On clicking on done , when saveChanges is called I need to call

grid.igHierarchicalGrid("dataBind"); and expand the grid using

var parentGrid = $("#igGrid").igHierarchicalGrid("rootWidget");

var domElement = parentGrid.rowById(rowID);

if (domElement != null) {

 $("#igGrid").igHierarchicalGrid("expand", domElement, function () {



After this is called the grid is refreshed with the latest values from the DB and the grid is expanded, but when I click on the filter icon on any of the columns and click on any option e.g Starts with it throws the above Js error.

I do not need to refresh the grid from the DB but want to have filter functionality work as it is.

Can you please help me with this?
