I'm going to answer my own question: create the bean for the target "builder" page in the session scope, not the request scope. Having several cups of coffee, a walk, and a long think, led me to this logical conclusion (if I want to manipulate a bean that exists in a session data structure, then the bean I copy it to has to exist accross multiple pages too). However I still have an uneasy feeling that I may be doing this the wrong way.
Any comments appreciated. Getting a bit frazzled with all this.
