Problem with clustered sessions

Problem described in the forum at http://forum.springsource.org/showthread.php?t=86144
It seems fairly easy to fix this at the source, re-put the conversationContainer at end of FlowExecutorImpl.launchExecution (or at end of SessionBindingConversationManager.beginConversation() as mentioned in forum).

Workaround right now is using a custom filter with the app which re-puts the conversationContainer at end of every request. Something like below filter:

public class SpringWebflowWorkaroundFilter implements Filter {
private static final String WEBFLOW_CONVERSATION_CONTAINER_KEY = "webflowConversationContainer";
public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws IOException,
ServletException

{ chain.doFilter(request, response); springWebflowWorkaround(((HttpServletRequest) request).getSession()); }

private void springWebflowWorkaround(HttpSession session) {
if (session == null) return;
// reput the conversationContainer after every request
Object conversationContainer = session.getAttribute(WEBFLOW_CONVERSATION_CONTAINER_KEY);
if (conversationContainer != null)

{ session.setAttribute(WEBFLOW_CONVERSATION_CONTAINER_KEY, conversationContainer); }

}
}
