Tomhawk 20051214 is breaking my program

[Yee CN]

The myfaces-api.jar and myfaces-impl.jar are from 1.1.1 release. Component nav_1 is a navigationMenuItem:   <t:navigationMenuItem id="nav_1" itemLabel="#{bundle['nav_Home']}" action="go_home" />   I also tried using the nightly built of myfaces-impl and myfaces-api – but they gave me other problems. This got me a bit nervous – that there could be some fundamental flaw in the way I use JSF.   Any idea?   Many thanks, Yee   --------------------------------------------------- 10:04:07,092 ERROR [jsp]:704 - Servlet.service() for servlet jsp threw exception java.lang.IllegalArgumentException: Component nav_1 is no UICommand       at org.apache.myfaces.taglib.UIComponentTagUtils.setActionProperty(UIComponentTagUtils.java:237)       at org.apache.myfaces.taglib.UIComponentTagBase.setActionProperty(UIComponentTagBase.java:172)       at org.apache.myfaces.custom.navmenu.HtmlNavigationMenuItemTag.setProperties(HtmlNavigationMenuItemTag.java:76)       at javax.faces.webapp.UIComponentTag.findComponent(UIComponentTag.java:392)       at javax.faces.webapp.UIComponentTag.doStartTag(UIComponentTag.java:219)       at org.apache.jsp.home_jsp._jspx_meth_t_navigationMenuItem_0(org.apache.jsp.home_jsp:343)       at org.apache.jsp.home_jsp._jspService(org.apache.jsp.home_jsp:189)       at org.apache.jasper.runtime.HttpJspBase.service(HttpJspBase.java:97)       at javax.servlet.http.HttpServlet.service(HttpServlet.java:802)       at org.apache.jasper.servlet.JspServletWrapper.service(JspServletWrapper.java:322)       at org.apache.jasper.servlet.JspServlet.serviceJspFile(JspServlet.java:314)       at org.apache.jasper.servlet.JspServlet.service(JspServlet.java:264)       at javax.servlet.http.HttpServlet.service(HttpServlet.java:802)       at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:252)       at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:173)      at org.apache.catalina.core.ApplicationDispatcher.invoke(ApplicationDispatcher.java:672)       at org.apache.catalina.core.ApplicationDispatcher.processRequest(ApplicationDispatcher.java:463)       at org.apache.catalina.core.ApplicationDispatcher.doForward(ApplicationDispatcher.java:398)       at org.apache.catalina.core.ApplicationDispatcher.forward(ApplicationDispatcher.java:301)       at org.apache.myfaces.context.servlet.ServletExternalContextImpl.dispatch(ServletExternalContextImpl.java:415)       at org.apache.myfaces.application.jsp.JspViewHandlerImpl.renderView(JspViewHandlerImpl.java:234)       at org.apache.myfaces.lifecycle.LifecycleImpl.render(LifecycleImpl.java:352)       at javax.faces.webapp.FacesServlet.service(FacesServlet.java:107)       at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:252)       at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:173)       at org.apache.myfaces.component.html.util.ExtensionsFilter.doFilter(ExtensionsFilter.java:129)       at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:202)       at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:173)       at com.traleva.erp.web.filter.HibernateFilter.doFilter(HibernateFilter.java:56)       at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:202)       at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:173)       at de.mindmatters.faces.spring.support.RequestHandledFilter.doFilter(RequestHandledFilter.java:150)       at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:202)       at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:173)       at com.traleva.erp.web.security.SecurityFilter.doFilter(SecurityFilter.java:80)       at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:202)       at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:173)       at org.apache.catalina.core.StandardWrapperValve.invoke(StandardWrapperValve.java:213)       at org.apache.catalina.core.StandardContextValve.invoke(StandardContextValve.java:178)       at org.apache.catalina.core.StandardHostValve.invoke(StandardHostValve.java:126)       at org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:105)       at org.apache.catalina.core.StandardEngineValve.invoke(StandardEngineValve.java:107)       at org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:148)       at org.apache.coyote.http11.Http11Processor.process(Http11Processor.java:868)       at org.apache.coyote.http11.Http11BaseProtocol$Http11ConnectionHandler.processConnection(Http11BaseProtocol.java:663)       at org.apache.tomcat.util.net.PoolTcpEndpoint.processSocket(PoolTcpEndpoint.java:527)       at org.apache.tomcat.util.net.LeaderFollowerWorkerThread.runIt(LeaderFollowerWorkerThread.java:80)       at org.apache.tomcat.util.threads.ThreadPool$ControlRunnable.run(ThreadPool.java:684)       at java.lang.Thread.run(Thread.java:595)
