I have the same problem since Glassfish 3.1, 3.1.1, 3.1.2 and now 4.0 when I go out from a CRUD JSF page to other page.
The error is:
Grave: WELD-000019 Error destroying an instance Managed Bean [class control.intranet.MotoristaController] with qualifiers [@Default @Named @Any] of control.intranet.MotoristaController$Proxy$_$$_WeldSubclass@28a047fc
where "MotoristaController" is just a sample, this occurs with all CRUDs from my webapp, that uses Conversation Scope from CODI.
I use now JSF 2.2, CODI 1.0.6, Richfaces 4.3.5, JPA 2, Hibernate 4.3.5 and DB Firebird 2.5.2.
But this problem is the same since some years ago.
I would to know if there is some configuration to show what object injected by Weld is blocking the correct destruction of my Managed Bean.
please increase the log level to DEBUG (simply add "org.jboss.weld.level=FINE" to the logging.properties file in your domain) so that we could analyze the cause.
