Use cases for detached models are e.g. database data. As the data are already stored in the database there is no need to keep them in the model, and potentially copy them across a cluster. Model data get detached / released at the end of the request and re-attached at the beginning of the next request. Remember there may be minutes between requests and you may not want to keep all the data in memory. If think your use case is different. Wicket always creates a session because it maintains the component hierarchy across requests. Your component could very easily be based on a shared model maintained in the session and you don't have to care about relasing it from session, because wicket takes care of releasing the session (and your model). IMO it is straightforward and very easy. . Juergen ------------------------------------------------------- SF.Net email is sponsored by: Discover Easy Linux Migration Strategies from IBM.
