We are also trying to find the right balance of how much we move to declarative. It will depend on how well we get Web Flow to fit in. With Wicket being Controller-less and wanting to launch right into the home page, Web Flow is a clear candidate to do initial data load and logic to determine the

Also, because we run in very large clusters, redirects are out of the question due to the potential that the second request hits a different server before HTTP session has been properly persisted/shared. Can't you set up server affinity for the cluster to avoid that from occurring?

We use server affinity but you can't guarantee same server and I can't go in with a 100% plan. We have had funny routing in some cases where requests from the same user even bounce from one data center to another... and back. We've done a lot of work to prevent these things but in the end it's

Phil, Would an event-centric approach simplify things? I'm thinking that you could then have multiple listeners for a given event and the various listeners would not have to be aware of one another. This might reduce the task/sub-task interactions. Adding errors, or refreshing components could
