Spring MVC one input field form
===

what is the best way in Spring MVC to send to server only one field in form? I need to send select box value, but also I want the select-box to be pre-filled with right value.

Normally I would have some form backing object, and bind him to form, but when I have only one field to send, I don´t need any form backing object. But than I connot use form:form and form:select for binding becouse it requires field in form backing object to be specified. 

Thanks.
