There is a mention of Grails in most of the Griffon references. I want to understand whether the basic features of Grails are supported - like CRUD like editors with a few commands, widely used plugins - like security, UI, search, filter, hibernate.
The reason behind Grails being mentioned is that Griffon is inspired by it; it even borrows code from grails (on the build side mostly).
The plugin ecosystem continues to grow, the following is a list of plugins that are shared by both frameworks (same or similar behavior): REST, protobuf, codenarc, code-coverage, J2D/GFX, remoting(hessian/rmi), xml-rpc, ws, jabber, gpars, scala, clojure, easyb, spring.
Peesistence plugins are starting to emerge, current ones include: GSQL (Groovy sql), Db4o, CouchDB, Neo4j, MongoDB. These plugins provide direct acces to their persistence backends, they do not provide domain class support. Another batch of plugins will do that, i.e, GORM-like domain classes.
