The project ZKGrails on Google Code started 2.5 years ago. The public first release there was 0.5. We have been blending ZK's best practices and Grails' ways of doing RIA together for the past 2 years. This results in a rapid and robust framework for developing Grails-based RIA applications.

ZKGrails 1.0 is released today!

You may find a presentation summerising ZKGrails features on its project page:

You can usually install the ZK plugin using the following commands:

$ grails install-plugin zk

and

$ grails install-plugin zk-ee

We also setup some roadmap for future versions of ZKGrails.
