There is a sort order property on NodeRelation. But it seems like this property is not taken into consideration when calling GetChildren on IContentLoader and passing a content reference to a node.
Entries are not sorted correctly in the Item List view in the new catalog manager either.
I'm able to sort entries by getting them via ILinksRepository, but that's an extra unnecessary call.
Is this by design, or shouldn't GetChildren care about the sort order? If not, how are entries sorted when calling GetChildren?
I'm on version 7.6.1 (Update 13 I think)
This is confirmed as a bug, please see http://world.episerver.com/Support/Bug-list-beta/bug/114577/.
This bug is now resolved and finding its way to the release.
