Thanks Martin, I'll have to look at this. For now I just went back to using the Session. My form was going to need to nest maps of maps to N levels. And the values that could be set for some of the maps could be a String[] or List[]. I got fed up trying to figure out how to get this to play nice using request scope.
I'm going to look at how other frameworks (maybe even Struts2) handle these nested item issues with backing beans using Request scope. (I happen to be a fan of Stripes but haven't looked at how they manage this behind the scenes either because I'm swamped with work.)
