Hello Rickard,

Thanks for trying logback!

The problem with parametrized logging wasn't on your side.

It's now fixed. I made a test case (ch.qos.logback.classic.MessageFormattingTest), to
check that.

The corrected code was committed. You can checkout the project by using the following
svn co http://svn.qos.ch/repos/logback/trunk DESTINATION_DIR

Nothing special needs to be done in order to use parametrized logging. It's built in 
logback and any configuration can benefit from it.

Thanks for your feedback, do not hesitate to email the list again if you encounter 
any other problems.
