Comparisons (uppermost VM) calls a method in ConfigComparisons (another VM).

{code:java}
@DomainService(nature = NatureOfService.VIEW)
@Named("knife.Comparisons")
@RequiredArgsConstructor(onConstructor_ = {@Inject})
public class Comparisons {
    private final ReleaseComparisons releaseComparisons;
    private final ConfigComparisons configComparisons;
[...]
 {code}

{code:java}
@DomainService(nature = NatureOfService.VIEW)
@Named("knife.ConfigComparisons")
@RequiredArgsConstructor(onConstructor_ = {@Inject})
@Slf4j
public class ConfigComparisons {
    private final MessageService messageService;
    private final Configurations configurations;
    private final Stages stages;
    private final com.kn.ife.Properties properties;
[...]
{code}

{code:java}
@DomainObject(logicalTypeName = "knife.ConfigComparison")
public class ConfigComparison implements Comparable<ConfigComparison> {
[...]
{code}
