Hi, I'm attempting to deploy a MyFaces 1.1.5 based portlet to JBossPortal2.4.1 (bundled with JBossAS) - i'm getting a long stream of exception from MyFaces, on the lines of: | 11:36:33,909 ERROR [FacesConfigurator] failed to configure class org.apache.myfaces.renderkit.html.ext.HtmlRadioRenderer | java.lang.ClassCastException: org.apache.myfaces.renderkit.html.ext.HtmlRadioRenderer | at org.apache.myfaces.config.FacesConfigurator.configureRenderKits(FacesConfigurator.java:754) | at org.apache.myfaces.config.FacesConfigurator.configure(FacesConfigurator.java:149) | at org.apache.myfaces.portlet.MyFacesGenericPortlet.initMyFaces(MyFacesGenericPortlet.java:210) | at org.apache.myfaces.portlet.MyFacesGenericPortlet.init(MyFacesGenericPortlet.java:128) | at javax.portlet.GenericPortlet.init(GenericPortlet.java:270) | at org.jboss.portal.portlet.container.PortletContainer.initPortlet(PortletContainer.java:387) | an exception for each MyFaces component. I've tried "upgrading" the portal to MyFaces 1.1.5 (by simply overwriting the myfaces api/impl Jar in the tomcat.sar jsflibs folder with the newer ones). but it doesn't seem to help. Any ideas on how to solve this - does my application need to be compiled against MyFaces 1.1.4 - the same version as in the original bundled tomcat jsflibs?
