             Summary: 'Bookmark no longer valid' CursorError caused by HierarchicalCollectionView's conversion of CollectionEventKind.REPLACE into CollectionEventKind.REMOVE
                 Key: FLEX-34440
                 URL: https://issues.apache.org/jira/browse/FLEX-34440
             Project: Apache Flex
          Issue Type: Sub-task
          Components: Advanced Data Grid, mx: Tree
    Affects Versions: Apache Flex 4.13.0
            Reporter: Mihai Chira
            Assignee: Mihai Chira
             Fix For: Apache Flex 4.14.0


*Steps to reproduce*:
# Create a HierarchicalCollectionView with the structure below
# Create a HierarchicalCollectionViewCursor, and call seek(new CursorBookmark(10));
# Call setItemAt(new DataNode*("Replaced Node"), 1) on the collection of companies (effectively replacing "Region(2) -> City(1) -> Company(2)TBR" with a new node)

*Expected behaviour*: no error.
*Actual behaviour*: this runtime error is thrown:
Error: Bookmark no longer valid.
