Add Form - required field bypassed if data filtred

Hi All!
I have add form where one column is filled by “Choise” component. The field is required. But there is conditions so sometimes all possible variants from Choise are filtered. In this case normally user should not be able to add new record as it marked “required”
BUT
as all variant filtred out “choise” component just disappear and form let to add record with empty column!

how to block possibility to add record in this case?
Looks like a bug for me.

Thanks in advance.

If you can determine the list of choices before the user opens the form, you can block their opportunity to open that form, if that choice list is empty.
