It's already in the Seam Faces module.

Hi,

It's in Seam Faces module but it doesn't work :

https://issues.jboss.org/browse/SEAMFACES-44

You can use this custom annotation http://www.verborgh.be/articles/2010/01/06/porting-the-viewscoped-jsf-annotation-to-cdi/ while this bug is not fixed.
But it's a temporary solution, you can't use Seam Facelet with it and some other minor stuffs.

Saying the Seam Faces @ViewScoped does not work is a mis-representation. The @ViewScope does work, but one has to make sure the beans are Serializable, and you can't use it on Producer methods. Also, if you post back to the same form, be sure to use null, rather than a navigation case if you want the scope to be preserved.

I've been using it myself in several applications, and it works fine so long as you stay within the boundaries of what it's currently capable of. And hopefully we can address these issues in a future version of Seam Faces.

Hi Brian,

I'm surprised because I can't make @ViewScoped working with Weld. I've got a JBoss AS 6.0.0.Final (name="weld-api.jar" specVersion="1.1.Beta2", name="weld-core-jsf-only.jar" specVersion="1.1.0.CR3") and Seam Faces 3.0.2.Final.

Here my bean :

import java.io.Serializable;

import javax.annotation.PostConstruct;
import javax.inject.Named;

import org.jboss.logging.Logger;

//import be.verborgh.enterprise.context.ViewScoped;
import javax.faces.bean.ViewScoped;

@Named("TestViewscopeBBean")
@ViewScoped
public class TestViewscopeBBean implements Serializable {

     private static final long serialVersionUID = 1022525016745203651L;

     private static final Logger logger = Logger.getLogger(TestViewscopeBBean.class);
     private String chaineATester;

     @PostConstruct
     public void init() {
          chaineATester = "Phase init.";
     }

     public void appelFonction() {
          logger.info("Appel de méthode.");
     }

     public String getChaineATester() {
          return chaineATester;
     }

     public void setChaineATester(String chaineATester) {
          this.chaineATester = chaineATester;
     }
}

And my error when I try to display my page :

What is my mistake if @ViewScoped works well ?

Thanks you in advance for your help.

Sounds like you are trying to use a recent version of Weld with JBoss AS 6? Is that the case? Have you tried your test with the version of Weld that ships with AS 6 (vanilla AS6)? Or try AS7?

Also, try deploying the faces-viewconfig example. It has @ViewScoped beans in it, and is known to work.

As far as i understand:
Mojarra does not serializable the bean into viewmap - MyFaces does.

So Weld with Seam ViewScoped does only work with Mojarra but how about clustering then?

ViewScoped with OWB works for example without problems because OWB beans are serializable.

didier Aug 19, 2011 4:28 AM (in response to franekgc)

Brian,

I've got a JBoss AS 6.0.0.Final and the version of Weld is the one which is shipped. I didn't try with AS7.

I will try the faces-viewconfig.

Ok I found why, I had an error with the view scope because my javax.faces.STATE_SAVING_METHOD was client. With server it works.

Yes, I've just had this same problem. After changing the state from client to server the error went away. But I think that it is very important to save state in the client as it save resources like memory on the server. It would be nice if there was another way instead of this to prevent this bug. Saving state in the client is very important. Again, as I already said before, I hope that the @ViewScoped is included in the next version of the CDI specification, so we don't need to use libraries to use such an important and handy scope in our applications.

Saving on the client increases page size thouroughly and also increases CPU for parsing/serializing view at the page. Server mode has its shortcomings, but makes http responses much faster/

That's been the typical argument between the two. It's a very fine line to walk for each application to consider.
