The DataSource's property groupPaging: true prevents the Grid's group from expanding if it has a defined groupHeaderColumnTemplate.
Also reproducible in the Core wrapper where an error is thrown: kendo.all.js:8743 Uncaught TypeError: Cannot read property 'hasSubgroups' of undefined
groupPaging is not compatible with the groupHeaderColumnTemplate
groupPaging and the groupHeaderColumnTemplate should be compatible
Kendo UI version: 2021.2.616

Hi Telerik Team,
I am also affected by this bug and wanted to check if the process of fixing it could be accelerated?
Or is there at least a better workaroud than just getting rid of the GroupHeaderColumnTemplate configuration as stated in the this forum post?
Thank you!
Janick
