Server behaviours in Dreamweaver CC2017
I have 'acquired' the 'Database and Server Behaviors' add-on from the Adobe site but CC2017 apps, add-ons can (Adobe says) only be updated through the Creative Cloud Desktop app.
When I did eventually get the add-on to install (confirmed by the Creative Cloud Desktop activity log) it did not provide any access to database / server behaviors as promised by the documentation. I can only conclude that the add-on doesn't work with CC2017 despite what Adobe says.
So the WebAssist extension isn't going to be very helpful.
