> *Steps to reproduce A*: run [HierarchicalCollectionViewCursor_FLEX_34424_Test|https://git-wip-us.apache.org/repos/asf?p=flex-sdk.git;a=blob_plain;f=frameworks/tests/unitTests/mx/collections/HierarchicalCollectionViewCursor_FLEX_34424_Test.as;hb=develop] - ideally with a previous version of HierarchicalCollectionViewCursor, HierarchicalCollectionView and LeafNodeCursor, to see how it fails..
> *Steps to reproduce B*:
> # 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 (correctly) 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)
