> addSortField method in the AdvancedDataGridEx works inconsistently

>
> Key: FLEX-33158
> URL: https://issues.apache.org/jira/browse/FLEX-33158
> Project: Apache Flex
> Issue Type: Bug
> Components: ADG:MultiColumnSorting
> Affects Versions: Adobe Flex SDK 4.5 (Release)
> Reporter: Robert Bar
> Assignee: Justin Mclean
> Priority: Minor
> Fix For: Adobe Flex SDK 4.5 (Release)
>
> Original Estimate: 24h
> Remaining Estimate: 24h
>
> Please assume you have the ADG instance which has a data provider set to an
> ArrayCollection with custom compare function associated with the Sort object.
> The Sort object contains some fields, so that the ADG shows many sorting
> arrows.
> If you ctrl+click header of an unsorted column, then ADG reuses the existing
> Sort object and adds the field to the collection, so that your custom
> comparison function is still in use. Next, if you click header of another
> column, so that only one column is sorted, then as the result, ADG will
> replace the custom Sort object with blank Sort object and the custom
> comparison function is lost.
> Basic workaround:
> coll.addEventListener("sortChanged", sortChangedHandler);
> private function sortChangedHandler(event : Event) : void
> {
> if (coll.sort)
> coll.sort.compareFunction = myCustomSortFunction;
> }
