Well, the point I was getting at was, in a dynamic form you would n't know what the form fields are going to be and so you can't use the form bean anyway. And like Craig mentioned in another thread, you will have to manipulate your parameterMap/parameterValues from the request yourself. Instead, if the framework was working with the parameterValues to begin with you wouldn't have this problem, right?
