Re: Grails and Spring AOP

Hi,

I am desperately trying to make Spring AOP work in my Grails project. I define
an advice on a service method, which works fine, but as soon as the pointcut
matches and the advice is executed, Grails throws an exception:

"java.lang.IllegalArgumentException: object is not an instance of declaring
class"

I guess this has something to do with Groovy and meta objects? Not sure.

Since I have seen Graeme saying on this mailing list that Spring AOP works just
fine in Grails, I am wondering what I am doing wrong.

Thanks,
Matthias

PS:
Here is my resources.xml, it's just for testing purposes right now (MyAspect is
annotated with @Aspect and defines a public method "foo"):

<?xml version="1.0" encoding="UTF-8"?>
