I have a complete working demo of spring webflow checked in under my username in the ICEsoft SVN repository. The working demo requires the following update to the class SeamUtilities found in the icefaces-compat/src/main/java/com/icesoft/util/SeamUtilities

The code below should handle the conditional case where (2 == springLoaded) (Line 537):

         try {
                String flowExecutionKeyFinderClassName = "com.icesoft.spring.webflow.FlowExecutionKeyFinder";
                log.fine("Creating instance of: " + flowExecutionKeyFinderClassName);
                Class flowExecutionKeyFinderClass = Class.forName("com.icesoft.spring.webflow.FlowExecutionKeyFinder");
                Object flowExecutionKeyFinderInstance = flowExecutionKeyFinderClass.newInstance();
                //see
                if(null != flowExecutionKeyFinderInstance) {
                    value = flowExecutionKeyFinderInstance.toString();
                }
                if (null != value) {
                    //Spring Web Flow 2.x confirmed
                    flowIdParameterName = "org.springframework.webflow.FlowExecutionKey";
                }
            } catch (Exception e) {
                log.log(Level.WARNING,"Unable to load spring flow execution key finder");
            }

An integration class should be defined by application integrators as follows (will describe this in the Wiki/Tutorial):

package com.icesoft.spring.webflow;

import org.springframework.webflow.execution.RequestContextHolder;

import java.util.logging.Logger;

/**
 * @author ICEsoft Technologies, Inc.
 *
 * Purpose of this class is to provide access to the Spring Webflow RequestContextHolder
 * while not introducing Spring Webflow as a build or runtime dependency unless its actually being
 * used.
 *
 */
public class FlowExecutionKeyFinder {

    private static Logger log = Logger.getLogger("com.icesoft.spring.webflow");

    public FlowExecutionKeyFinder() {
        log.fine("Constructed FlowExecutionKeyFinder - must be a Spring Webflow 2+ environment.");
    }

    public String toString() {
        String key = RequestContextHolder.getRequestContext().getFlowExecutionContext().getKey().toString();
        log.fine("Returning webflow key: "+ key);
        return key;
    }
}
