Inheritance issue in Errai CDI?
Hello together
I plan to develop a gwt application with dynamic loading of gui parts. I try to load bean instance with the IOCBeanManager against interfaces with a simple inheritance:
public interface A
{
}
public interface B extends A
{
}
@ApplicationScoped
public class AImpl implements A
{
}
@ApplicationScoped
public class BImpl implements B
{
}
Now, when i try to lockup this beans against their interfaces, the bean manager seems to ignore the inheritance after one step:
beanManager.lookupBeans(A.class).size() == 1
beanManager.lookupBeans(B.class).size() == 1
I found nothing about a definition of this behavior in the documentation and took a look in the source of the IOCBeanManager. There the lookup is done through a Map with one class typing .. thats the answer.
A further problem in this relation is the resolving of injection points:
A Qualifier
@Qualifier
@Retention( RetentionPolicy.RUNTIME )
@Target({ElementType.FIELD, ElementType.TYPE})
public @interface Q
{
}
and append it to class B:
@Q
@ApplicationScoped
public class BImpl implements B
{
}
My entry point class:
@EntryPoint
public class EntryPoint{
@Inject
@Q
private B b;
}
Then i get the follow compiler error:
[INFO] org.jboss.errai.ioc.rebind.ioc.exception.UnsatisfiedDependenciesException: @> ch.apkern.ui.client.view.ClientApplication
[INFO] - field org.jboss.errai.codegen.meta.MetaField:ch.apkern.ui.client.view.ClientApplication.loginPresenter could not be satisfied for type: ch.apkern.ui.client.view.defaults.presenter.DefaultPresenter

[INFO] Note: configure an alternative to take precedence or remove all but one matching bean.
But when i append also on class A its own qualifier then it works well.
Is this behavior as expect?
