problem with ExtendedType in Cayenne 4.2

Hi!

We are migrating from 4.0.2 to 4.2. We have a class that implements ExtendedType. 
In 4.0.2 the method:

public SourceId materializeObject(ResultSet rs, int index, int type) throws Exception 

was invoked, but not in 4.2.

We register our class in this way:

public class DataloyOracleAdapter extends OracleAdapter {

	public DataloyOracleAdapter(@Inject RuntimeProperties runtimeProperties, 
			@Inject(Constants.SERVER_DEFAULT_TYPES_LIST) List<ExtendedType> defaultExtendedTypes,
			@Inject(Constants.SERVER_USER_TYPES_LIST) List<ExtendedType> userExtendedTypes, 
			@Inject(Constants.SERVER_TYPE_FACTORIES_LIST) List<ExtendedTypeFactory> extendedTypeFactories,
			@Inject(Constants.SERVER_RESOURCE_LOCATOR) ResourceLocator resourceLocator, 
			@Inject ValueObjectTypeRegistry valueObjectTypeRegistry) {
		super(runtimeProperties, defaultExtendedTypes, userExtendedTypes, extendedTypeFactories, resourceLocator,
				valueObjectTypeRegistry);
		setSupportsGeneratedKeys(false);
		//super.setPkGenerator(new DataloyPkGenerator());
		
		setSupportsBatchUpdates(false);
		this.extendedTypes.registerType(new SourceIdType());
	}


}


What is wrong? What should be changed?

Many regards,
Andrea
