I have a form that gets pre-populated in an action. So in my PrepMappingAction it does a mappingForm.setYears(years).
The years populate a select box.
There are other input fields on the form that get validated. If they fail, server performs validation and then tries to forward back to that form. But I get an error saying that the options in the select box are null. This is because those were in the request and they dissapear after server validation.
I suggested using the session, and I got mocked despite being relatively new to web programming.
