Congratulations! I have been using tapestry 4 since the beta versions and find is a pleasure to develop with. So much so that I chose it for the project at work. This is (as always) a project with very tight deadlines, lots of integration with various technologies and other projects. The new features of tapestry 4 has really helped speed up development and produce succinct less error prone code. The integration with hivemind and annotations, and the ability to inject services into pages components is such a great feature, and the fact that the parameters just work makes things a lot easier. The new validation system is a lot more powerful and easy to use, I was able to produces a required dhtml dojo text area in no time at all. Thanks again to everyone involved :)
