Extending Seam core class and overriding methods

[asookazian]

@Scope(ScopeType.EVENT)
@Name("org.jboss.seam.core.manager")
@Install(precedence=BUILT_IN)
@BypassInterceptors
public class Manager

org.jboss.seam.annotations.Install
public static final int      APPLICATION      20
public static final int      BUILT_IN      0
public static final int      DEPLOYMENT      30
public static final int      FRAMEWORK      10
public static final int      MOCK              40

I'd like to @Override some methods in this Seam component for learning/experimentation purposes and substitute with my own.  What is the best approach to do this?

I'm guessing write a public class that extends Manager and use @Install(precedence=MOCK) or anything higher than BUILT_IN (0).

public class NewManager extends org.jboss.seam.core.Manager {
     
     private static final LogProvider log = Logging.getLogProvider(NewManager.class);

     @Override

        {      
           ConversationPropagation propagation = ConversationPropagation.instance();
           
           if (propagation.getPropagationType() == null)

              return;
           }

           switch (propagation.getPropagationType())
           {
              case BEGIN:
                 /*if ( super.isLongRunningConversation() )

                    throw new IllegalStateException("long-running conversation already active");
                 }*/
                 beginConversation();
                 
                 if (propagation.getPageflow() != null)
                 {

                 }
                 break;

I forgot an @Override for public void beginConversation(), so I added that and reproduced exceptions.

Note:

2009-07-12 08:00:11,841 INFO  [org.jboss.seam.init.Initialization] two components with same name, higher precedence wins: org.jboss.seam.core.manager
2009-07-12 08:00:11,841 INFO  [org.jboss.seam.init.Initialization] two components with same name, higher precedence wins: org.jboss.seam.core.manager

It would be nice if Seam logged the names (package and class) at DEBUG level.

Why is it logging that line twice?

I only see one reference to an installed component named org.jboss.seam.core.manager after those logging statements:

08:00:12,210 INFO  [Component] Component: org.jboss.seam.core.manager, scope: EVENT, type: JAVA_BEAN, class: org.jboss.seam.example.booking.NewManager

So why is this line being hit?

public static FacesManager instance()
   {
      return (FacesManager) Manager.instance();
   }

as evidenced by my debugger brkpt and this output:

08:08:05,159 ERROR [SeamPhaseListener] swallowing exception
java.lang.ClassCastException: org.jboss.seam.example.booking.NewManager_$$_javassist_seam_2
     at org.jboss.seam.faces.FacesManager.instance(FacesManager.java:313)

From a UI perspective, the home page renders fine (booking app - 2.1.2.GA).

When I login, I see this again:

08:09:25,960 ERROR [ContainerBase] Servlet.service() for servlet Faces Servlet threw exception
java.lang.ClassCastException: org.jboss.seam.example.booking.NewManager_$$_javassist_seam_2
     at org.jboss.seam.faces.FacesManager.instance(FacesManager.java:313)

So what is the fix here?

It helps to carefully analyze the call stack in the stack trace:

protected void afterRenderResponse(FacesContext facesContext)
   {
      //do this both before and after render, since conversations 
      //and pageflows can begin during render
      FacesManager.instance().prepareBackswitch(facesContext);
      
      PersistenceContexts persistenceContexts = PersistenceContexts.instance();
      if (persistenceContexts != null) 
      {
          persistenceContexts.afterRender();
      }
      
      ExternalContext externalContext = facesContext.getExternalContext();
      Manager.instance().endRequest( externalContext.getSessionMap() );
      FacesLifecycle.endRequest(externalContext);
   }

So there is the reference to FacesManager which did not require an injection.

Ok, so now I'm not sure if I can extend the original Manager class with my NewManager class....

Any recommendations other than altering the src code for org.jboss.seam.core.Manager?

I renamed my class from NewManager to Manager and reproduced the exception...

Hi Arbi,

do you remember if/how you resolved this?
I want to install an extended FacesMessages component with capabilities like e.g. message filtering by (resource bundle) key.
I had a look at the StatusMessages source and i expect it to bring up the same problems you experienced (static methods instance(), runTasks() that will probably be bound somewhere)...

Thanks a lot, best regards
Flo

StatusMessages should work fine, it was designed for extension.

Arbi's problem was that he was inheriting from org.jboss.seam.core.Manager instead of org.jboss.seam.faces.FacesManager.
