Hi Arnaud,

I have used session to store my dataContext

something like this

public DataContext getSessionDataContext(){
        synchronized(this){
            if(this.dataContext==null){
                this.dataContext = DataContext.createDataContext();
            }
        }
        return this.dataContext;
    }


anywhere I need this, I perform this

DataContext dctx = ((MyAppSession)getSession()).getSessionDataContext();

I think it may not solve the serialization issue, if session objects are
serialized. But you avoid creating DataContext at every page.

Not sure if this helps you.

You may want to see how DataBinder[1] has implemented it.
