I am using Spring to handle an update form with multiple rows. The form jsp displays multiple lines of a format like this: CustomerID PriceList Month Amount
...where amount is an input text box. Since Spring allows POJOs as the command objects, I was assigning the results of this form to a Java.util.List. Unfortunately, when it came to to display validation errors in the Jsp, I found I could not figure out how to directly bind to any field that incurred an error (say, numeric format)- THey are all unnamed fields in a List! Do I need to start over or is there a good way of handling multiple input fields in a Spring form? (FYI- using a SimpleFormController with validations happening in onBindAndValidate)

Update: I have tried to implement the suggestions from this blog: Guide to Porting Struts to Spring but to no real advantage.
