Peter Hall commented on FLEX-34101:
-----------------------------------
We've run into the same issue, which appears to be caused by a change in how
CollectionEvents are distpatched when a collection is sorted.
Previously, when a property change causes an item to not match the filter, the
collection would dispatch a CollectionEvent with kind "remove". Since 4.10 the
event will have kind "update". DataGroup is not notififed that the item has
been removed and gets into an inconsistent state.
> Regression from 4.8 to 4.10: Spark list doesn't refresh with filterFunction
