Gavin, I apologize if I've done something wrong. I've proceeded to follow your advice and download the beta version of seam from the downloads page. I've already analyzed the booking example and I'm trying to get something simple that I can understand set up. After changing all the jars in my project to use the ones from the beta I just downloaded, I get the original exception I posted. 11:16:31,240 ERROR [PhaseListenerManager] Exception in PhaseListener RENDER_RESPONSE(6) afterPhase java.lang.IllegalStateException: No active application context at org.jboss.seam.core.Pages.instance(Pages.java:298) at org.jboss.seam.jsf.SeamStateManager.saveSerializedView(SeamStateManager.java:47) at org.ajax4jsf.framework.ajax.AjaxStateManager.saveSerializedView(AjaxStateManager.java:83) at org.ajax4jsf.framework.ajax.AjaxContext.saveViewState(AjaxContext.java:417) at org.ajax4jsf.framework.renderer.AjaxPhaseListener.afterPhase(AjaxPhaseListener.java:103) at org.apache.myfaces.lifecycle.PhaseListenerManager.informPhaseListenersAfter(PhaseListenerManager.java:89) at org.apache.myfaces.lifecycle.LifecycleImpl.render(LifecycleImpl.java:390) at javax.faces.webapp.FacesServlet.service(FacesServlet.java:138) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:252) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:173) at org.jboss.seam.servlet.SeamRedirectFilter.doFilter(SeamRedirectFilter.java:32) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:202) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:173) at org.ajax4jsf.framework.ajax.xmlfilter.BaseXMLFilter.doXmlFilter(BaseXMLFilter.java:67) at org.ajax4jsf.framework.ajax.xmlfilter.BaseFilter.doFilter(BaseFilter.java:223) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:202) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:173) at org.jboss.web.tomcat.filters.ReplyHeaderFilter.doFilter(ReplyHeaderFilter.java:96) 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.jboss.web.tomcat.security.SecurityAssociationValve.invoke(SecurityAssociationValve.java:175) at org.jboss.web.tomcat.security.JaccContextValve.invoke(JaccContextValve.java:74) 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:869) at org.apache.coyote.http11.Http11BaseProtocol$Http11ConnectionHandler.processConnection(Http11BaseProtocol.java:664) at org.apache.tomcat.util.net.PoolTcpEndpoint.processSocket(PoolTcpEndpoint.java:527) at org.apache.tomcat.util.net.MasterSlaveWorkerThread.run(MasterSlaveWorkerThread.java:112) at java.lang.Thread.run(Thread.java:595) If you don't have time to look at this, that's okay. I'm just trying to learn how to integrate the two technologies together. Thanks, Ben. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3981333#...
