Hello, I've been experimenting with logback core/classic 0.9.27 (and slf4j 1.6.1) with Tomcat 6.0.29, Java 1.6 on Solaris for the past couple days, and have hit a wall viz conditional configuration processing. When I include a conditional like the following in my configuration file, nothing in the file is processed beginning with and after that directive: <if condition='property("HOSTNAME").contains("hactar")'> <then> <property name="foo" value="bar"/> </then> </if> Even a conditional as simple as the following causes processing to abort: <if condition='"foo".equals("foo")'> <then> <property name="foo" value="bar"/> </then> </if> No errors seen in the ViewStatusMessagesServlet. Am I doing something wrong? Thanks. /mcr
