Description

Currently the only way to sort by complex fields (e.g. "address.street") is to not specify any sort fields and to use a custom compare function which knows which fields to check.

Expected behaviour: The code below sorts the items by the address.street field:

const sortByNameAscending:Sort = new Sort();
sortByNameAscending.fields = [new SortField("address.street", false, false)];
_sut.sort = sortByNameAscending;

Note this will allow FLEX-34837 to be fixed.
