9 Jun 2018 by Gerry Schmitz

The "banner" is just another "view"; I see no issue slotting in with the "other views". It should have it's own "model" that responds to "incoming messages" posted from "other models" (or whatever). You do not appear to be treating it as a view but as a "user control" (?); and therefore your...
