Using Eclipse. If you're using Eclipse to compile your project, then you're using Scala 2.7.2-RC1/2 which has different method signatures than the version that Lift is compiled against: 2.7.1
So, please exit Eclipse, got into your project directory and type: mvn clean jetty:run and see if the problem goes away.
