Leonardo Uribe commented on MYFACES-3581:
-----------------------------------------
It could be good to know the exact lines, to keep them as reference. Checking
again the stack trace, I can see that resolveClass() is not called in this
case, and instead resolveProxyClass() is called. Sounds like a not common use
case but valid. Anyway, the patch is incomplete, because it does follow the
protocol used in ClassUtils.classForName(), which is try to resolve the class
using the context classloader and then use the class classloader. Still need
some work and a justification about when it happens, but now sounds more
reasonable.

> 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.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:
> http://stackoverflow.com/questions/11371573/jsf2-0-ejb-injection-into-viewscoped-causing-myfaces-to-cfne/11371846#11371846
> @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>
> This will cause the following exception:
