Rails - Sep 2008 - edge rails config.cache_classes = true breaks applications

when using current edge rails, i am getting trouble when using the
production environment -- i tracked down the problem to the following
line

config.cache_classes = true

if i disable the class caching, everything works just fine, when
enabling the cache_classes, lots of errors get dropped -- see the output
below:


error #1:

when i comment out the parts with "file_field" i keep getting the
following errors:

demo_mode? is a method that checks if the rails env is either
development or staging.
everything just works fine with rails 1.2, 2.0 and 2.1 ...


any ideas?

thanks a lot!
