Subject @PageActivationContext vs. ComponentMethodAdvice
Date Fri, 04 Jul 2008 22:35:20 GMT

Earlier I had stated that you should have found a way to use
ComponentMethodAdvice, advising the dispatchComponentEvent() method,
to implement support for the @PageActivationContext annotation.

I now think I was in error; the ComponentMethodAdvice approach only
works if the advice can be implemented in terms of the public API of
the component, or the method parameters.  @PageActivationContext
requires access to the fields of the component.  Short of changing
ComponentMethodAdvice to allow access to private fields of the advised
component, it simply is not a good fit.
