I forgot to add something...

Tree data which is lazy loaded should be placed into the session else
you are likely to get all sorts of confusing problems.

from albatross import LazyTreeIterator

def restore_tree(ctx):
    # Create the tree root and fetch the previous state of the tree.
    ctx.locals.root = create_tree_root(ctx)
    ctx.add_session_vars('root')
