> the ModelDrivenInterceptor fetche twice the model by default, this is really anoying when we back the getModel on a database action.
> here is the code I propose :
> public class ModelDrivenInterceptor extends AbstractInterceptor {
>     public String intercept(final ActionInvocation invocation) throws Exception {
>         final Object action = invocation.getAction();
>         if (action instanceof ModelDriven) {
>             final ModelDriven<?> modelDriven = (ModelDriven<?>) action;
>             //avoid fetching the model twice.
>             final Object model = modelDriven.getModel();
>             if (model != null)
>                 invocation.getStack().push(model);
>         }
>         return invocation.invoke();
