wekk you want to hide the region when 3 conditions are valid:
- data is not loaded yet
- you have items
- data is being loaded
according to Patrick - hasItems() returns undefined/true/false - not loaded, has items or no items (but loaded),
so you can do it in one, with strict checks, show only when there are really no items, otherwise hide:
dmx-show="scNews.data.repeatNews.hasItems() === false"
very important the 3 === for strict checks
