groupPaging and groupHeaderColumnTemplate cause an error in the Grid

Bug report

The DataSource's property groupPaging: true prevents the Grid's group from expanding if it has a defined groupHeaderColumnTemplate.

Reproduction of the problem

  1. Open this Dojo
  2. Try to expand the Grid's groups

Also reproducible in the Core wrapper where an error is thrown: kendo.all.js:8743 Uncaught TypeError: Cannot read property 'hasSubgroups' of undefined

Current behavior

groupPaging is not compatible with the groupHeaderColumnTemplate

Expected/desired behavior

groupPaging and the groupHeaderColumnTemplate should be compatible

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!
