In case anyone is interested.
The example stores the routes in a map. These routes are persisted. So if you send the same message id it will not update the entry in the map.
When you back out of the detail route, the route is disposed. But if you send the same message it will not update the route that is stored. So producing the error when it tries to run the route again.
The solution if you want to send the same message each time is to remove the entry for the map before trying to add a new one.
Of course the routes map keeps on getting larger.
The same applies to the _item map. That keeps all entries permanently so keeps on growing.
