[Tbnl-devel] [hunchentoot-devel] 404 page

[Patrick May]

Hans,

	That would be “debugging by public embarrassment” in action.  ;-)

	Removing the incorrect eql specialization still doesn’t result in my 404 page being displayed.  Do I have to subclass acceptor to get it to work?

Thanks,

Patrick

In your method definition, you are trying to specialize the ACCEPTOR argument on (EQL *TEST-ACCEPTOR*)), but *TEST-ACCEPTOR* in that definition will be evaluated at compile-time, not at run-time.  Thus, you're probably specializing on NIL or some other random object.  Is there any reason why you want to specialize on a particular instance rather than the class of the acceptor (or T)?
