I don't think the proxy stuff is your problem. Is your DAO class
interface-based (it should be). Meaning, do you have a DAO interface

Yes, the classes are interface-based. Eg.,
public class ProtocolDAO extends JpaDaoSupport implements IProtocolDAO
I think it's down to fiuring out what I've done wrong in my Panel. I
get a classcastexception at the "(Protocol) item.getModelObject();"
line. Listed below is both my Panel and the appropriate signature from
ProtocolDAO.findAll().
public class ShowProtocolsPanel extends Panel {
@SpringBean(name="ProtocolDAO")
private ProtocolDAO dao;
public ShowProtocolsPanel(String id) {
super(id);
IModel protocolModel = new LoadableDetachableModel() {
protected Object load() {
return dao.findAll();
}
};
add(new ListView("eachItem", protocolModel) {
@Override protected void populateItem(ListItem item) {
final Protocol protocol = (Protocol)
item.getModelObject();
item.add(new Label("keyword", protocol.getKeyword()));
item.add(new Label("description",
protocol.getDescription()));
}
});
}
}
public class ProtocolDAO extends JpaDaoSupport implements IProtocolDAO {
...
@Transactional(readOnly = true)
@SuppressWarnings("unchecked")
@Override
public List<Protocol> findAll(final int... rowStartIdxAndCount) {
...
}
...
}
