[seam-dev] Issue resolved with JBoss AS 7 CR1 and Seam Social

Yes. However this is currently not possible due to a limitation in Seam Config. What is interesting is that having a beans.xml in WEB-INF/classes/META-INF makes stuff partially work ;-)

WEB-INF/classes/META-INF is not the right location for beans.xml in a war, but it's the only places Seam Config can read from :-(
