Dan Allen has done some work (in my holiday absence, thanks Dan) to align the Seam/Wicket integration with Seam Solder (formerly Weld Extensions). With this release, the CDI/Wicket integration is part of Seam rather than part of Weld. This makes sense for a number of reasons, the most important of which being that it's our intention to eventually support other CDI implementations besides Weld.
The project now has a page on Seam's website as well as a github project for your forking pleasure.
The release is available on the Seam Downloads page as well as through maven.
Thanks again to Dan for his work, and to the entire Weld/Seam community for continuing to improve on these frameworks.
