Which version of JBoss Tools are you using?
Hello, thanks for a fast reply, I'm using 3.1.0 M2 (Development milestone for Eclipse 3.5)
Content assist for xhtmls has been improved In 3.1.0 M3. It will show all tags/attributes from TLDs within class-path of your project. See http://www.jboss.org/community/wiki/NewKBplug-inandCodeAssistinJBossTools310M3 for details.
But I'm not sure about visual tab of XHTML editor... I hope VPE guys will answer if there support of the newest RichFaces components.
3.1.0 is not available yet. But you can download the latest nightly build or wait a liytle bit for official release.
Allright, thanks very much :).
