@PageActivationContext vs. ComponentMethodAdvice

[Howard Lewis Ship]

Igor,

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.

I also realized that the advice approach requires a change of
ComponentMethodAdvice. That's why I felt comfortable about using the
PageActivationContextWorker.
