Hi, everyone
I'm a newbie of logback. I found a small mistake of the logback manual in Chapter 3: Logback configuration.
A /logger/ element takes exactly one mandatory name attribute, an optional level attribute, and an optional *aditivity *attribute, which admits the values /true/ or /false/.
The *aditivity* *should be **additivity* *, right? I tested for it and the **aditivity doesn't work.* * *-- Sent from Hangzhou, 33, China Joan Crawford <http://www.brainyquote.com/quotes/authors/j/joan_crawford.html> - "I, Joan Crawford, I believe in the dollar. Everything I earn, I spend."
