It appears just linking an form input with a path is not enough. There is some manual parsing or binding required. Thanks

If you have a property editor for User, the dropdown list and the checkboxes in the midterm can be easily handled by <form:select> and <form:checkbox>. The reason why binding a <form:input> is simple is because both the property in the server object and the input in the HTML form are strings. But when the property is an object, e.g. a User object for committee chair or a List<User> for committee members, a property editor is needed to translated it to string in an HTML form.
