Hi all, I'm implementing an application that saves Order into database. Obviously, Order has many OrderItems, and I tend to allow user add and remove OrderItems dynmically on screen by using Ajax. I prefer that for each Ajax addOrderItem call, it adds a new OrderItem in an session scoped bean name "order". The problem is, for the Spring Annotation, I cannot find an annotation that maps form bean with an session scoped bean. @ModelAttribute and @SessionAttributes only support form backing bean for the conversation between HTTP GET and HTTP method. Is there any solution to store and map a session bean with the Spring MVC annotation?
