Igor,
I'm not using a loadable detachable model because I was hoping to get the
list of foos directly from the Bar object, as opposed to having a dedicated
dao method to get the list of foos, which seems to defeat the benefit of
using JPA's object chaining. To answer your question, here's my
implementation of dataprovider#model():
public IModel model(Object object)
{
return new Model((Serializable) object);
}
Of course, it's very possible I'm missing a fundamental point about loadable
detachable models...
