When running ICEfaces 1.7.1 with Spring Web Flow the back/forward browser navigation does not work properly. On of the benefits of Spring Web Flow is the built in well-defined support for using the browser back button, however, when Spring Web Flow is configured to work with ICEfaces, this does not work. Please see the stack trace below. If you need more information do not hesitate to write randahl@rockit.dk
