Subject: Re: conflict between active record and Log4R

I think the activerecord use Ruby's Inner Logger to overwrite the
Log4r's Logger.
you can see my post here

http://groups.google.com/group/comp.lang.ruby/browse_frm/thread/4281944fd2f359cb/27040ba3c4aa7b9a?q=log4r&rnum=4#27040ba3c4aa7b9a

It would be helpful
