----------------------------------
Summary: HierarchicalCollectionViewCursor.current returns null
when last item of current level selected and previous sibling is removed
Key: FLEX-34424
URL: https://issues.apache.org/jira/browse/FLEX-34424
Project: Apache Flex
Issue Type: Bug
Components: Advanced Data Grid, mx: Tree
Affects Versions: Apache Flex 4.12.1
Reporter: Mihai Chira
Assignee: Mihai Chira
I'm about to commit a unit test which uncovers this bug. Until then, brief
steps to reproduce:
# Create a HierarchicalCollectionView with a hierarchical structure with at
least 2 levels of depth. See structure at the end of the ticket for example.
# Create a HierarchicalCollectionViewCursor via
HierarchicalCollectionView.createCursor().
# Call HierarchicalCollectionViewCursor.seek(11), which makes
HierarchicalCollectionViewCursor.current ==
"Region(2)->City(1)->Company(2)->Department(2)->Employee(3)"
# Remove "Region(2)->City(1)->Company(2)->Department(2)->Employee(1)" from its
collection
*Actual behaviour*: HierarchicalCollectionViewCursor.current becomes null.
*Desired behaviour*: HierarchicalCollectionViewCursor.current stays
"Region(2)->City(1)->Company(2)->Department(2)->Employee(3)".
*Example structure*:
Region(1)
Region(2)
Region(2) -> City(1)
Region(2) -> City(1) -> Company(1)
Region(2) -> City(1) -> Company(2)
Region(2) -> City(1) -> Company(2) -> Department(1)
Region(2) -> City(1) -> Company(2) -> Department(1) -> Employee(1)
Region(2) -> City(1) -> Company(2) -> Department(1) -> Employee(2)
Region(2) -> City(1) -> Company(2) -> Department(2)
Region(2) -> City(1) -> Company(2) -> Department(2) -> Employee(1)
Region(2) -> City(1) -> Company(2) -> Department(2) -> Employee(2)
Region(2) -> City(1) -> Company(2) -> Department(2) -> Employee(3)
Region(2) -> City(1) -> Company(2) -> Department(3)
Region(2) -> City(1) -> Company(2) -> Department(3) -> Employee(1)
Region(2) -> City(1) -> Company(2) -> Department(3) -> Employee(2)
Region(2) -> City(1) -> Company(2) -> Department(3) -> Employee(3)
Region(2) -> City(1) -> Company(2) -> Department(3) -> Employee(4)
Region(2) -> City(1) -> Company(3)
