RE: [aspectj-users] Confused by cflow interaction - totally new confusio

["Mik Kersten" <beatmik@xxxxxxxxx>]

Hi Keith,

Any mismatches between the crosscutting structure views and the advice that
actually runs can be very confusing, and is probably the result of a bug
with the view.  Even without the enhancements suggested in my last email the
structure views should show *any* place that cflow advice *might* execute.

I'm a bit confused about your mentioning that only some of the advice is
"executed".  Could you please put together a bug report that describes any
mismatch between what executes and what shows up in the view?  Please
include this source code, the advice that actually ran, and the advice that
the structure view displayed.

Thanks,

Mik
