[jbosstools-issues] [JBoss JIRA] Commented: (JBIDE-6957) Erroneous error about decorators and delegate types

[Viacheslav Kabanovich (JIRA)]

    [ https://jira.jboss.org/browse/JBIDE-6957?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12548318#action_12548318 ] 

Viacheslav Kabanovich commented on JBIDE-6957:
----------------------------------------------

Please, clear out for me the example from tck.

We have these classes and interfaces

public class FooDecorator extends AbstractFooDecorator implements Foo, Bar {...}
public interface Foo extends Baz, Serializable {}
public class AbstractFooDecorator implements Boo {}
public interface Bar {}
public interface Baz {}
public interface Boo {}

We have delegate point
@Inject @Delegate FooBar foobar;
where
public interface FooBar extends Foo, Bar...

Since these objects are not in a 'broken' section, it is assumed that delegate point has all required bean types: Foo, Bar, Baz, and that Boo is not required.

But why Boo is not a bean type of FooDecorator? It is its bean type as of managed bean, and it is interface and not superclass.

> Given a decorator like
> @Decorator
> public abstract class FloodingDecorator implements CodeFragmentManager, Serializable
> {
>    private static final long serialVersionUID = -4615837206290420112L;
>    @Inject @Delegate 
>    private CodeFragmentManager codeFragmentManager; 
> }
> JBoss Tools errors, telling me "The delegate type must implement or extend the decorated type Serializable [JSR-299 §8.1.3]"
> However, it doesn't have to implement serializable - the delegate type must be one of the decorated types, not all of them
