You can solve this using Wickets PropertyModels. Map the Components
that are part
of your domain models as usual (CompoundPropertyModel?) and use
PropertyModels for the others:
TextFieldString tf = new TextFieldString(myWicketID, new
PropertyModel(PageOrComponent.this, spezialAttribute));
than
Wiket provides PropertyModel class to map to values accessible via
expressions.
You always can write your own models. For instance you can employ Spring
property expressions if you'd like map on collection projection.
You can yield values using great Google collections framework.
