[cdi-dev] Lifecycle Callback Interceptor and @Target "METHOD"

I need ElementType.METHOD since I want to use the same interceptor binding annotation for both business method and lifecycle callback interception. However I have a dedicated @AroundInvoke and @PostConstruct interceptor method. If I declare my annotation at method level I would expect that @AroundInvoke is applied only.

I just found the related sentence in the interceptor spec. "Method-level interceptors may not be associated with a lifecycle callback method of the target class." This statement seems to be OK but I believe this doesn't mean that my interceptor binding annotation may not specify ElementType.METHOD.

Why do you need ElementType.METHOD? You cannot use method-level bindings for lifecycle callback interceptor methods. This has been reverted from the interceptors spec.

Hi all!

While testing Weld 2.0.0.CR4 I have been running into a DefinitionException because of an interceptor that contains one @AroundInvoke and one @PostConstruct method. Since I use this interceptor at class AND method level it declares @Target({ElementType.METHOD, ElementType.TYPE}). The error message seems to indicate that I can not have a lifecycle callback interceptor with @Target METHOD:

"WELD-000619 An interceptor for lifecycle callbacks Interceptor XX declares and interceptor binding interface YYY with METHOD as its @Target."

Is this true? I just checked the current CDI 1.1 and Interceptor 1.2 spec and could not find this kind of restriction.
