NotSerializableException on ViewScoped ManagedBean with CDI Injected properties

Question

I'm trying to create a scalable JSF application. I would like to save view states on client side but I have troubles with ViewScoped ManagedBean with CDI Injected attributes.

SomeService.java :

@Singleton
public class SomeService {
    // ...
}

SomeBean.java

@ManagedBean
@ViewScoped
public class SomeBean implements Serializable {

            @Inject
            private SomeService someService;
}

Unfortunately glassfish fails to serialize someService which I don't want to be serializabled but re-injected.

I tried to make it transient which ends up to a NullPointerException when accessing someService after de-serialization.

What shall I do?

I'm aware that I could use CDI ViewScoped with Seam Faces or CODI but I want to minimize at most dependencies.

I could also wait for JEE7 which will provide @ViewScoped for CDI but we won't be using JEE7 before months.

UPDATE :
I just wanted to add that I was using embedded EJB bundled in a jar which is itself linked to my war. NotSerializableException's stack trace has the following message : com.company.core.service.__EJB31_Generated__SomeService__Intf____Bean__

Why are you injecting an EJB by CDI's @Inject instead of EJB's @EJB? — BalusC
I don't really get the difference, according to link it's better to use @EJB in some cases. I tried to change from @Inject to @EJB without any improvement. Do you have any recommendation? — Alexandre Jacob

I don't like to self respond to my own questions but after some more research I found that it was a bug in Mojarra 2.1.6 (I'm using Glassfish 3.1.2.2) which is now solved in Mojarra 2.1.20.

To update Mojarra you just need to download a fresher version (eg: https://maven.java.net/content/repositories/releases/org/glassfish/javax.faces/2.1.20/javax.faces-2.1.20.jar) and place it in the $GLASSFISH/modules directory as javax.faces.jar.
