David Blevins commented on MYFACES-3581:
----------------------------------------
The proposed patch looks great -- not sure why that didn't occur to me.
On the spec requirements note, it's somewhat orthogonal as the root issue is
derialization of any java.lang.reflect.Proxy and should be fixed regardless,
but I'd say, yes. It's certainly a requirement for EJB and CDI that container
supplied refs like @EJB and @Resource survive passivation/activation. I
haven't checked the JSF spec, but if there is no such text we could maybe get
that added so there is a more direct A to B wording. It's currently sort of A
to B to C in that CDI has this requirement spelled out for all passivation
capable scopes. A primary one is @ConversationScoped which applies only to JSF.

> Key: MYFACES-3581
> URL: https://issues.apache.org/jira/browse/MYFACES-3581
> Project: MyFaces Core
> Issue Type: Bug
> Affects Versions: 2.1.8
> Environment: Oracle JVM 1.7.04, Apache TomEE
> Reporter: Jonathan S Fisher
> Assignee: Leonardo Uribe
> Attachments: MYFACES-3581-2.patch, MYFACES-3581.patch
>
> Original Estimate: 48h
> Remaining Estimate: 48h
>
> If you have a ViewScoped ManagedBean, @EJB injection appears to fail when an
> ajax request is submitted. This may be because the MyFacesObjectInputStream
> is not using the context class loader.
> See original bug report here:

> @ManagedBean
> @ViewScoped
> public class BlogMB implements Serializable {
> private static final long serialVersionUID = 1L;
> @EJB
> private CategoryService categoryService;
> }
> Here's the view code:
> <h:commandLink value="#{category.name}">
> <f:setPropertyActionListener
> target="#{blogMB.selectedCategory}"
> value="#{category}" />
> <f:ajax
> listener="#{blogMB.filterPostsByCategory()}"
> execute="@this"
> render=":blogPosts" />
> </h:commandLink>
