I understand why the grouped column can't be filtered by
null.
I am looking for documentation on how to prevent the range filter on a grouped column from allowing a
null selection in the first place.
Something like:
minCheck = 1;
OR when
null keep the range selection open until something is selected
On the attached image, Year is grouped. If you attempt to filter to 1 year, you might click deselect all. Which results in
null and the following error.
Here is the error.
