After upgrading to 2019.3.1023, server filtering fails after the first search. Chrome console shows the following error. The control is no longer functional after this error occurs. Any ideas?
VM1837:3 Uncaught TypeError: Cannot convert undefined or null to object

Hello Steven,
We are not aware of such issue with the MultiColumnComboBox. Here's a link to the Server Filtering demo: https://demos.telerik.com/aspnet-mvc/multicolumncombobox/serverfiltering
It uses version 2019.3.1023, the component can be filtered multiple times consecutively and no exception is thrown. How does your MultiColumnComboBox configuration differ from that of the linked demo?

Hi Ivan
One difference I can think of is in my application I search for numbers rather than text.
The records that I can search for are a list of numeric IDs up to 6 digit long.

Hi Steven,
Attached to this reply you can find a sample runnable project that demonstrates MultiColumnComboBox with server filtering. Filtering is done over the NumericID field, which is a 6 digit long int in the items data.
