Producing dependent instance into SessionScoped bean

[lfryc]

Hi,

I have problem with producer method injecting actual instance to SessionScoped bean.

It seems, that injection point behave as SessionScoped, but I annotated producer as Depedent, so each use of my InjectionProvider should obtain new reference for toInject, shouldn't it?

@Named @SessionScoped
public class InjectionProvider implements Serializable {
    private String toInject = "initial";

    @Produces @Dependent @ToInject
    public String getToInject() {
        return toInject;
    }

    public void setToInject(String toInject) {
        this.toInject = toInject;
    }
}

@Named
@SessionScoped
public class InjectionConsumer implements Serializable {

    @Inject @ToInject transient String toInject;

    public String getFromInject() {
        return toInject;
    }
}

@Qualifier
@Target({FIELD, PARAMETER, TYPE, METHOD})
@Retention(RUNTIME)
public @interface ToInject {
}

First invocation of InjectionConsumer.getFromInject gave initial as expected, but when we call InjectionProvider.setToInject("othervalue"), it got:

InjectionProvider.getToInject =  othervalue

InjectionConsumer.getFromInject = initial

Is it my misunderstanding of producer or can it be bug?

Workaround for this sample is use InjectionConsumer as RequestScoped, but it isn't desired solution.

Thans for reply,

(I verified that it misbehaves on  latest JBoss 6 Snapshot .
But it fails also on GlassFish v3.)

I think it's because the injection of toInject into InjectionConsumer happens at first reference to InjectionConsumer and since it's a dependent value, it's not proxied and you end up with the initial value

Try this:

1. Use InjectionConsumer as RequestScoped
2. Call InjectionConsumer.getFromInject within a requestScope
3. Call InjectionProvider.setToInject(othervalue)
4. Call InjectionConsumer.getFromInject within an other requestScope

Is this the good solution?

@Named
@SessionScoped
public class InjectionConsumer implements Serializable {

    @Inject Instance<String> toInject;

    public String getFromInject() {
        return toInject.get();
    }
}

It seems work for me.

@Inject @ToInject Instance<String> toInject

and toInject.get() could also be an option(?)

I started writing my response before you posted, honest! ;-)
