Select in Spring

[Pavan Tummala]

Whats the best way to deal with html:select in Spring framework, Is spring:bind helpful?

Pavan,

Typically in Spring MVC, you will manually extract the select parameter value by overriding the onBindAndValidate method in your controller. For example:

    protected void onBindAndValidate(HttpServletRequest request, Object                             command, BindException errors) {
        Roster roster = (Roster) command;
        Long id = Long.valueOf(request.getParameter("type_id"));
        roster.setType(getGamerServices().findContestantType(id));
    }

This ensures that the parameter is set during the binding and validation process and the workflow will result in a call to onSubmit if all is OK or showForm (with appropriate error messages) if not. The jsp code containing the select should be wrapped inside a spring:bind tag.
