                 Key: LBCORE-103
                 URL: http://jira.qos.ch/browse/LBCORE-103
             Project: logback-core
          Issue Type: Improvement
          Components: Appender
    Affects Versions: 0.9.15
         Environment: Windows XP, Java 1.5 Sun JVM, Tomcat 5.0.27
            Reporter: Johan Bos
            Assignee: Logback dev list
            Priority: Trivial


I was expecting "message" implicit variable to contain the full message rendered by the %message or %msg from the pattern, but the recommanded way of logging,
using LOG.debug("I want to log an object {}", object); is only formatted in the event.getFormattedMessage(), event.getMessage <=> message, but only contains the "I want to log an object {}"
so if my matching string for the expression setting for the EvaluatorFilter is the dynamical part I can't never match my string, instead it got "{}".

So, it would be less confusing for users to find in the documentation an explicit information on what message variable contains, and does not contain!

Thank you

I would be happy to explain my point if you find it unclear or irrelevant.
