Major Description
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="#
"
value="#
" />
<f:ajax
listener="#
"
execute="@this"
render=":blogPosts" />
</h:commandLink>
This will cause the following exception:
