I have a custom entity and form where I have enabled a sub-grid. I want to expand the space as the number of records increases, so I checked ''Automatically expand to use available space'' box, and I have published many times. but it's not working! nothing different then before. I consulted some experienced developer, they advise me to check that have another sub-grid checked this box, But there is NO. Is anyone else experiencing this problem or have a solution? Thanks
