Re: [aspectj-users] IllegalStateException: Can't answer binding questions prior to resolving ?
|
It is best if I can work on these issues with a failing testcase, but
if you can't construct one (I think we've ironed out most of the
simple bugs now so it's only ones with subtle interactions that are
left...) then I'll take a look based on the stack trace. Did you
raise a bug yet? I tend to lose bugs that only get mentioned on the
mailing list...
cheers,
Andy
