Since this week I am allowed to post to the jsr-314-open mailing list and thus considered a member of the JSR-314 extended expert group. I am very happy with this, because I can finally raise my concerns with JSF 2.0 and 2.1 and also join some interesting discussions.
I already started a thread about the targets attribute of composite components. I kinda consider it an epic fail, and I already got consent of other EG members. Check it out: http://lists.jboss.org/pipermail/jsr-314-open-mirror/2010-October/000604.html
