Supposing it's a Vertex with VertexProperties that is deserialized (and not
only a VertexProperty on its own), will this really make the VertexProperty
link to the right parent Vertex? It looks like this will create another one.
However, I've recently found a nice way to make a deserializer sort of "context
aware" in order to, when a Vertex deserializer deserializes its own
VertexProperties, it can give to the VertexProperty deserializers the Vertex
object that's "above" them - the VertexProperty's parent. I haven't had time to
propose a fix here in TP but I intended to do so soon if you guys are
interested
