Hi, This post with reference to: http://www.jboss.com/index.html?module=bb&op=viewtopic&t=106625 I want to migrate my application to use the latest Seam cvs (to test a fix which has been submitted) which requires jboss 4.2.0CR. It seems that jb4.2.0 uses the JSF1.2 RI and not the myfaces jsf as earlier. This is quite troublesome as I make use of quite a large number of tomahawk components. 1. Is it possible to use tomahawk with the JSF 1.2 RI ? 1.1. If so, how do I configure my web.xml/faces-config.xml ? by adding the tomahawk jar I get the following error: Error configuring application listener of class org.apache.myfaces.webapp.StartupServletContextListener 1.2 If not, will it be possible to downgrade from JSF 1.2 RI to myfaces 1.1 (both JBoss and Seam) ? Alternatively will I be forced to remove all tomahawk dependencies from my application (a major piece of work) ?
