Spring Data R2dbc Explicit Converter never called

Question

I have the following model:

@Table("organisation")
public class OrganisationModel {

  @Id
  @Column("id_organisation")
  private OrganisationId id;

  @Column("id_parent")
  private OrganisationId parentId;
}

The IDs in the database are Integers. The class OrganisationId simply wraps the Integers. To map the IDs I define the following Converters:

public class OrganisationModelReadingConverter implements Converter<Row, OrganisationModel> {
  @Override
  public OrganisationModel convert(Row source) {
    OrganisationModel model = new OrganisationModel();
    model.setId(new OrganisaitonId(source.get("id_organisation", Integer.class)));
    model.setParentId(new OrganisationId(source.get("id_parent", Integer.class)));
    return model;
  }
}

public class OrganisationModelWritingConverter implements Converter<OrganisationModel, OutboundRow> {
  @Override
  public OutboundRow convert(OrganisationModel source) {
    OutboundRow outboundRow = new OutboundRow();
    outboundRow.put("id_organisation", source.getId().getValue());
    outboundRow.put("id_parent", source.getParentId().getValue());
    return outboundRow;
  }
}

and register the Converters with:

@Configuration
public class R2dbcConfiguration {
  @Bean
  R2dbcCustomConversions customConversions(ConnectionFactory connectionFactory) {
    R2dbcDialect dialect = DialectResolver.getDialect(connectionFactory);
    List<Converter<?, ?>> converters = new ArrayList<>();
    converters.add(new OrganisationModelReadingConverter());
    converters.add(new OrganisationModelWritingConverter());
    return R2dbcCustomConversions.of(dialect, converters);
  }
}

I expect that the convert() methods of the registered Converters are called but they never are. The Bean for the R2dbcCustomConversions is initialised at start up.

What am I doing wrong here?
