Are you keeping reference to it anywhere within your Session-scoped beans?Periodically when I restart my webapp (tomcat 5.5), I get the following error. Should UIViewRoot be declared as 'transient' in session (or whatever is its' parent). Is this an JSF-RI (and not Facelets) question? thanks -nikita INFO: Deploying web application archive envmanager.war Jul 19, 2006 2:27:38 PM org.apache.catalina.session.StandardManager doLoad SEVERE:
