             Summary: Serialization problems in section "1.3.1. JSF example".
                 Key: CDI-708
                 URL: https://issues.jboss.org/browse/CDI-708
             Project: CDI Specification Issues
          Issue Type: Bug
          Components: Concepts
    Affects Versions: 2.0 .Final
            Reporter: Martin Andersson

Section "1.3.1. JSF example" provide an example of a class {{Login}}, that saves in its state an {{EntityManager}} reference and two {{Parameter}} references.

The JPA specification does not say that a {{Parameter}} instance is serializable.

This is also true for the {{EntityManager}} reference which is {{@Dependent}} (see section "1.3.3. Java EE component environment example"). JPA does not specify that the {{EntityManager}} is serializable and the EJB specification only specifies serialization semantics for passivation-enabled {{@Stateful}} EJB:s (which encourages the bean provider to not mark an {{EntityManager}} reference as transient, see EJB §4.2.1).
