If you configure a grid with a checkbox selection mode, and group summaries, when you collapse or expand a group the checkbox may disappear. It appears that this will happen to any rows that collapse/expand to where a summary record would have been.
Can be replicated in this grouping demo.
- Update the config to enable checkbox selection, and group summaries
- Note that row 5 is an empty group summary row
- Now collapse the first group
- Row 5 is now a record with a missing checkbox
