I am using Kendo UI v2015.1.318, specifically the kendo.web.js.
A requirement I have is to support IE8. While my code works on Chrome, Firefox, IE9-11, it breaks on IE8 during aggregation in a grid.
This is the datasource for the parent grid:
This is the shortened grid definition:
The point where it breaks is
On all browsers, except IE8 the aggregates object is an array of objects with length 3, which is correct, since I have defined 3 columns to sum up. On IE8 the length is 4, and the for-loop breaks, because aggregates is undefined.
What causes this behaviour and how can I fix this?
