Dan,
I just discovered @MemberGroups tonight. I did a little "fake it until you
make it" work and pushed it to Heroku[1]. By applying the Law of Demeter[2]
and names on the @MemberOrder annotation I have what may be a good way of
displaying @Aggregated objects in Wicket. Check out the Find All action
under Cargo. I've "exploded" each quasi-Aggregated object into Cargo so
that it has getters for each property that defer to the Aggregated property.
public class Cargo {
private RouteSpecification routeSpecification;
@MemberOrder(sequence="1", name="Route Specification")
public Location getRouteSpecificationOrigin() {
return routeSpecification.getOrigin();
}
...
}
Full Cargo class here[3].
Do you like this better (automatically creating member groups for
@Aggregated properties and faking them to Wicket) than creating a separate
panel? For my purpose I think the visual distinction given by member groups
is adequate.
