The “factory_etoile” (a collection factory) calling on the prototype “EtoileCarte.collection” with this hierachy :

*EtoileCarte.collection
** EtoileCarte.go
***Etoile.go
***Label

By this code :

		local idf = collectionfactory.create("#factory_etoile", pos, nil, props, 1)
		pprint (idf)

Give me things like that :

{ --[[0x7f4319166cf0]]
  hash: [/Label] = hash: [/collection99/Label],
  hash: [/EtoileCarte] = hash: [/collection99/EtoileCarte],
  hash: [/Etoile] = hash: [/collection99/Etoile]
}

Meaning, no hierarchy. I’m not sure I understand correctly. Is it normal ?
