Hi there everyone,

I have a curious problem. I've created a lookup service that is triggered by a smartfield on a form. When the form is displayed, the smartfield remains empty and turns red with the message "Treatment Error". When I look at the Eclipse IDE console, I see a BeanCreationException: could not create bean class message for my ContractTypeRestLookupService class.

The class is as detailed below:
public class ContractTypeRestLookupService extends AbstractRestClientHelper
    implements IContractTypeRestLookupService {

  protected static final String RESOURCE_PATH = "contrattype";
  public static final Logger LOG = LoggerFactory.getLogger(ContractTypeRestLookupService.class);


  // Fetch contract types from the REST server (TO DO!)
  private List<? extends ILookupRow<Integer>> getContractType() {
    ArrayList<ILookupRow<Integer>> rows = new ArrayList<>();

    rows.add(new LookupRow<>(1, "Full time"));
    rows.add(new LookupRow<>(2, "Part time"));
    rows.add(new LookupRow<>(3, "Temporary"));

    return rows;
  }

  @Override
  public List<? extends ILookupRow<Integer>> getDataByKey(ILookupCall<Integer> call) {
    return null;
  }

  @Override
  public List<? extends ILookupRow<Integer>> getDataByText(ILookupCall<Integer> call) {
    return null;
  }

  @Override
  public List<? extends ILookupRow<Integer>> getDataByAll(ILookupCall<Integer> call) {
    return getContractType();
  }

  @Override
  public List<? extends ILookupRow<Integer>> getDataByRec(ILookupCall<Integer> call) {
    return null;
  }
}


This is the console listing with the exception message:

Can anyone please help me figure out what I'm doing wrong?

Thanks a lot for your kind assistance.

Cheers,

Your at ContractTypeRestLookupService extends the class AbstractRestClientHelper which seems to require a IRestClientConfigFactory in org.eclipse.scout.rt.rest.client.AbstractRestClientHelper.createClientConfig().

You could add a dependency to your server application

    <dependency>
      <groupId>org.eclipse.scout.rt</groupId>
      <artifactId>org.eclipse.scout.rt.rest.jersey.client</artifactId>
    </dependency>


which should solve at least this error (JerseyClientConfigFactory is an instance for this bean).

See https://github.com/eclipse-scout/scout.rt/tree/releases/22.0/org.eclipse.scout.rt.rest.jersey.client
