Mihai Chira created FLEX-34440:
----------------------------------
Summary: 'Bookmark no longer valid' CursorError caused by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Error: Bookmark no longer valid.
