Hi, I see the following aspects:
1 experienced users migrating an application 2 novice users 3 effort in implementation Maybe a final decision can be postponed with being optimized for 3 right now. IMO a programming environment optimized for 2 that is as simple and consistent as possible should draw in more users.. -j -----Ursprüngliche Nachricht----- Von: Dan Haywood [mailto:d...@haywood-associates.co.uk] Gesendet: Mittwoch, 4.

I guess we're balancing this against the complexity within the framework, to be able to support both styles of programming model. So at the moment the framework is more complicated because it does need to support both modes. One plus if we do make this change is that @Programmatic goes away completely. A different perspective: this makes the framework more of an opt-in rather than an opt-out. I could argue that it also changes the "feel", to more of a library than a framework. That is, an Apache Isis v2 app is just a Spring Boot app with various domain objects, and they can be made visible in the UI if they are annotated. I'm about 60:40 myself for the proposal ... but that's perhaps because my head is in the "framework layer" at the moment rather than at the application layer. Anyone else?
