>          Components: Core
>    Affects Versions: 2.3.0.Final
>         Environment: JBoss AS 7.1.0.Final (JSF RI 2.1.5)

> The exception fails after render response phase if long running conversation is active and a bean in conversation scope (additions map) has page/conversation/session scoped outjection.
> Latest 2.3.1.CR1-SNAPSHOT (with JBSEAM-5045 fix): The same exception fails in ExceptionFilter after unhandled exception when there is active long running conversation and a component in conversation scope with a page scoped injection.
> The issue is not reproducible if http://java.net/jira/browse/JAVASERVERFACES-1685 is reverted. Call to equals in com.sun.faces.context.SessionMap#put (lines 132-138) introduced with 1685 fix causes injection/outjection to occur:
>         boolean doSet = true;
>         if (null != value && null != result) {
>             doSet = ! result.equals(value);
>         }
>         if (doSet) {
>             session.setAttribute(key, value);
>         }
