Re: [aspectj-users] JSF Project with AspectJ in Tomcat 5
|
I am not yet familiar with JSF but won' the bean action be invoked reflectively?
You may post here a stack trace you would get by throwing a fake
runtime exception from auxHello() and hello() methods.
This could be the cause as call pointcut does not match reflective calls
