Re: [aspectj-users] 'around advice a method call under cflow' does not w

[Andrew Eisenberg <andrew@xxxxxxxxxxxx>]

This is a fairly complex pointcut.  Just by eyeballing it, it is hard
for me to see what the problem is.  Whenever I am in a situation like
this and I need to find out why a pointcut is not matching, I try
breaking things down into simpler pointcuts and see if they match.

First, are you using AJDT and do you see the gutter annotations in the
places where you expect them to be?

Also, try creating advice for each of your named pointcuts.  In the
body of the advice, print something the sysout.  Once you have all of
your named, component pointcuts working properly, you can then start
combining them to create the pointcut that you actually need.

I hope this helps.
