Hi there again This pointcut sounds right, but the aspect is not applied at all.
around() : get(@Annotation * *.*) -> Matches everything correctly, but no return value bound around(Object val) : get(@Annotation * *.*) && args(val) -> Matches nothing I tried to fiddle with the proceedingJoinPoint.proceed() to get the field access return value, but this always returns null. Any ideas? Regards Mirko -----Ursprüngliche Nachricht----- Von: aspectj-users-boun...@eclipse.org [mailto:aspectj-users-boun...@eclipse.org] Im Auftrag von Sertic Mirko, Bedag Gesendet: Freitag, 19.
