We used the older appfuse 7 years ago and we like it. We're going to start on a big project and use Appfuse 3. We ran into this issue: http://issues.appfuse.org/browse/APF-1383. If we can't find a way to get this work then we have to drop Appfuse.
I think Appfuse is a good framework and it help when we start a project from scratch.
