Run setter on mixin??

[jdoklovic]

I'm trying to use a mixin that inherits from DelegatingIntroductionInterceptor and is instantiated by a DefaultIntroductionAdvisor.
The problem is that the mixin object needs to have a property set to run the method i'm trying to implement but i'm not sure how to do that since the advisor constructor runs: super(new MyMixinClass());

is there anyway to inject or run a setter on the mixin object itself?

Thanks!
