<@U13A9PZC0> yeah.  and i'm not recommending this for every app, but the app I'm thinking about has a big update problem.  One aspect of the program can update the javafx data structures optimistically then follow up with a model call.  For example, add to a treeview, then update a pojo collection.  However, this puts that code in a special status, wanting to ignore notification from the event bus.

it's more consistent if everyone responds to the notifications as though someone else initiated it

if you have a strong view/model pairing, then i might be more direct.  but i've seen the simple case grow rapidly
