Action chaining isn't just to access logic in two separate action classes, but is often necessary when intermediate input is required from the user, for example complex forms which need to be broken down into multiple pages, wizards if you like.
Since Struts 1 we have been sticking the user entered data in the session scope, which poses its own problems. I thought the big advantage of S2 was the ability to "easily" implement action chaining and let the framework deal with how to persist the data across multiple requests. But I'm finding that it's not the case.
