Mihai Chira updated FLEX-34853:
-------------------------------
Description:
{code}
_sut.addAll(from4To0); //values["name"]: Object4, Object3, Object2,
Object1, Object0
const sortByIndexAscending:Sort = new Sort();
sortByIndexAscending.fields = [new SortField("index", false, false,
true)];
_sut.sort = sortByIndexAscending;
_sut.refresh(); //should be: Object0, Object1, Object2, Object3,
Object4
//when
sortByIndexAscending.fields = [new SortField("name", false, true,
false)]; //should have no effect
//then
assertThat(_sut.getItemIndex(from4To0.getItemAt(i)) != -1); //an
RTE is thrown here
{code}
*Expected behaviour*: the collection should redo the sort when any of its
sort's flags changes, or whenever one of the sortFields' flags changes.
*Note*: the solution being pursued is to make Sort and SortField immutable. See
more of the discussion
