Bean instantiated twice

[pieter.martin]

Hi,

I am using weld in the standalone SE manner.

At the moment I only have 2 beans.

@ApplicationScoped
public class Entry {

     @Inject 
     TestInject testInject;
     
     public void train(@Observes ContainerInitialized event) {
          System.out.println("NeuralNetworkStart ");
          testInject.doStuff();
     }     
}

@ApplicationScoped
public class TestInject {

     public TestInject() {
          super();
          System.out.println("TestInject constructor");
     }
     
     @PostConstruct
     public void postContruct() {
          System.out.println("postContruct");
     }
     
     @PreDestroy
     public void preDestroy() {
          System.out.println("preDestroy");
     }

     public void doStuff() {
          System.out.println("doin stuff u know");
     }
     
}

The TestInject class is instantiated twice. Once before the ContainerInitialized event fires and again before the doStuff method call.

Further I noticed that the @PostConstruct fires but the @PreDestroy never fires.

What am I doing wrong?

Thanks

Ok I checked on the SE Guess example in the distro and it has the same behavior as explained above

Is this a bug or not?

Thanks

How is the JSF version behaving on this point?

Uhmm, don't know, going to sleep now but will have a look tomorrow.

Cheers

Still not sure about the jsf version's behavior (waiting for jboss6 to download) but I have spotted the ShutdownManager class.

So I

@Inject ShutdownManager shutdownManager;

and then call

shutdownManager.shutdown();

before the main thread exist.

This inturn calls the @PreDestroy methods of ApplicationScoped objects.

Cheers

Ok, another way I spotted now,

@Inject @Shutdown Event<BeanManager> shutdownEvent;
@Inject BeanManager beanManager;

and the before the mail thread exist call,

shutdownEvent.fire(beanManager);

I'll try to have a look at the double-instanciation thing over the next week, and will double-check the documentation to see if I can't clarify the use of the ShutdownManager.

Cheers,

Pete.
