Typically a custom request cycle for the actual object and store the key for getting access to the object in the session. If the cart is not a hibernate entity, but something really transient, I don't think there is any harm in putting it in the session, as long as you are certain you won't be doing resouce updates based on the session. Typically add/remove from carts are single requests that are synchronized on the session.
As for the property model, you can do this as well: add(new ShoppingCartPanel("panel", new PropertyModel(this, "session.cart "))); Martijn On 1/21/08, Martijn Lindhout <[EMAIL PROTECTED]> wrote: > > ok, and if the session isn't thread safe, where do I store my temporal > data? > > > 2008/1/21, Johan Compagner <[EMAIL PROTECTED]>: > > > > The session.
