Where do you have your LoadableDetachableModel declared? And what kind
of IDataProvider are you talking about? If it is wicket's
IDataProvider than it has to be serializable, because DataView/Table
keep it's reference.
LoadableDetachableModel is usually declared as anonymous class inside
component/page, which is serialized anyway, so the implicit reference
makes no difference.
