Marko Lukša created CDI-221: ------------------------------- Summary: Throw definition error if the set of decorated types of a decorator is empty Key: CDI-221 URL: https://issues.jboss.org/browse/CDI-221 Project: CDI Specification Issues Issue Type: Feature Request Reporter: Marko Lukša I propose the following addition to section 8.1: "If the set of decorated types of a decorator is empty, the container automatically detects the problem and treats it as a definition error." This would be helpful in cases where the developer is not aware that a decorator and decorated bean must share the same interface, and thinks that a decorator can be defined simply by extending the decorated class (as in the following example). {code} public class MyBean { public Object foo() {...} } @Decorator public class MyDecorator extends MyBean { @Inject @Delegate MyBean delegate; public Object foo() {...} } {code} Even though the spec does explicitly state that "superclasses are not decorated types of the decorator", throwing an error would probably save some people's debugging time. -- This message is automatically generated by JIRA.
