Copy property from old to new tree (using HierarchicalDataSource)

[Kake]

Hi

Currently using the treeView to display a "filesystem". when a user files the tree must refresh to sync the data (count etc)
When the is updated the tree goes back to the initial collapsible state. (the expanded property is provided from the backend)

Q: Is there a way to maintain the state or copy the state from the old to the new ?
