Mihai Chira commented on FLEX-33058:
------------------------------------
It wouldn't help, because the next loop in
{{HierarchicalCollectionViewCursor.findAny()}} will throw a similar RTE about
the "children" property, and then about the "GroupLabel" property. It's the
anonymous objects that are created by {{GroupingCollection2.buildGroups()}}.
I'll say more about the cause in the commit message when I put in a fix.
> RTE in HierarchicalCollectionViewCursor when a refresh occurs and old cursor
> had an enumerable property that new cursor item doesn't
