Hi,
is there a solution on Leopard to implement the autosaving of expanded/
collapsed state of an NSOutlineView (bound to Core Data via
NSTreeController).
I tried to implement outlineview:persistentObjectForItem; and
outlineView:itemForPersistentObject:. But it doesnt't work, because
NSTreeNode and NSManagedObject don't encode with NSKeyedArchiver.
Is there something I am missing, or couldn't state autosaving be done
in Leopard without 'hacks' like in Tiger?
Ralph.
