 Description  « Hide
We currently just provide simple collection/map wrappers. These mean that when we load the collection/map field we load all elements/keys/values. If we supported backed wrappers then we could provide lazy loading of elements etc.

Sort Order: Ascending order - Click to sort in descending order

No clear benefit of providing this feature since the ids of the elements are stored in the owner anyway, so we only ever just update the owner when the field is changed. Provision of lazy loaded SCO doesn't need backing stores since we have the ids and could just load them one by one for the collection field.
