This is all happening locally in my development environment.  I am using JBoss AS 5.1 and Seam 2.2.2.Final. Here is a snippet from the Seam Component that is failing: @Scope(ScopeType.CONVERSATION) @Name("scoringManagementAction") @Restrict("#{identity.loggedIn}") public class ScoringManagementAction implements Serializable, ScoringManager, Mutable {     private static final long serialVersionUID = -1266492462210968391L;     @Logger     private Log log; .... ....     @In(required = true, scope = ScopeType.SESSION)     @Out(required = true, scope = ScopeType.SESSION)     private BreadCrumbStackView breadCrumbStackView; .... ....     @Override     public boolean clearDirty() {         final boolean isDirtySet = this.scoringView.isDirty();         this.scoringView.setDirty(false);         return isDirtySet;     } Thanks for your help. -------------------------------------------------------------- Reply to this message by going to Community [https://community.jboss.org/message/725993#725993] Start a new discussion in Clustering Development at Community [https://community.jboss.org/choose-container!input.jspa?contentType=1&...]
