Is there any more information on this topic? (I may have missed it with project priorities shifting...)
It looks to me like it snuck in somewhere…
If you right-click a View, you can configure onStartup events and oShutdown events. In my (limited) testing over the last 60 seconds, they seem to work correctly (onStartup sets the text of a TextField to ‘Reset’, while the Designer has a default starting text of ‘First’. The TextField always shows ‘Reset’ as the text, even after manually changing it and then navigating to other Views and back, and after using the Browser “Back” button).
