[cdi-dev] [JBoss JIRA] (CDI-708) Serialization problems in section "1.3.1. JSF example".

[Martin Andersson (JIRA)]

    [ https://issues.jboss.org/browse/CDI-708?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13448697#comment-13448697 ] 

Martin Andersson commented on CDI-708:
--------------------------------------

Actually #2, I think I was wrong when it comes to the {{EntityManager}}. The CDI spec defines this guy as a "passivate capable dependency" as long as he was looked up through a CDI producer field.

> 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).
