[Flow] Using aspects to change EmailAddressValidator

[Steffen Wickham]

Happy new year everybody! Hope you got a good start.

But new year means even new problems to be solved. I ran into a problem
regarding AOP to intercept the EmailAddressValidator and don't know how
to "debug" it the proper way.
Please have a look at the following gist:
https://gist.github.com/anonymous/8251626

It is the very first time for me to program in AOP style but the new
e-mail validator isn't suitable for me so I will replace it with the old
RegEx Validation.
I also tried to write some log as shown in the definitive guide
examples, but there is no entry. For me, it seems that the pointcut
expression will fail. :-/

Is it possible to debug AOP in an easy way?

Greetings,
Steffen
