Is there perhaps a way in which you can convert a TreeModel to a JSON string. That way it can be stored and then later recreated using tree.parse()
?
Currently when attempting JSON.stringify(root)
it gives an obvious error about cyclic references (because children contain parents and parents contain children).
Use JSON.stringify(root.model)
instead.
