Your problem is that the catalog is not locatable itself during the
addition of its indexes (-> state within the create and add method),
therefore the location of the indexes cannot be located and the
NotYetError is raised. You can move your code to an
ObjectAddedEvent-subscriber for your object.
handler pseudo code:
def addCatalogAndIndex(obj, event):
sm = zapi.getNextSiteManager(obj)
catalog = Catalog()
addLocalUtility(sm, 'XY', ICatalog, catalog)
catalog[name] = Index(name, IAnyInterface)
