    public MyExampleDTO(MyEntity entity) {
        this.id = entity.getId().toString();
        this.customField = entity.getCustomField();
    }

}

Step1 Add mapping DTO->entity to corresponding VersionAwareResponseService.

    @Override
    protected ActionResultDTO<MyExampleDTO> doUpdateEntity(MyEntity entity, MyExampleDTO data,
            BusinessComponent bc) {
        if (data.isFieldChanged(MyExampleDTO_.customField)) {
            entity.setCustomField(data.getCustomField());
        }

        return new ActionResultDTO<>(entityToDto(bc, entity));
    }

Step2 Add fields.setEnabled to corresponding FieldMetaBuilder.

    @Override
    public void buildRowDependentMeta(RowDependentFieldsMeta<MyExampleDTO> fields, InnerBcDescription bcDescription,
            Long id, Long parentId) {
        fields.setEnabled(MyExampleDTO_.customField);
    }

Option 1 Enabled by default.

    @Override
    public void buildRowDependentMeta(RowDependentFieldsMeta<MyExampleDTO> fields, InnerBcDescription bcDescription,
            Long id, Long parentId) {
    }

Option 2 Not recommended. Property fields.setDisabled() overrides the enabled field if you use after property fields.setEnabled.

Step 2 Add fields.enableFilter to corresponding FieldMetaBuilder.

    @Override
    public void buildIndependentMeta(FieldsMeta<MyExampleDTO> fields, InnerBcDescription bcDescription, Long parentId) {
        if (configuration.getForceActiveEnabled()) {

Validation

Validation allows you to check any business rules for user-entered value. There are types of validation:

1) Exception:Displays a message to notify users about technical or business errors.

Business Exception: Live Sample · GitHub

Runtime Exception: Live Sample · GitHub

2) Confirm: Presents a dialog with an optional message, requiring user confirmation or cancellation before proceeding.

Live Sample · GitHub

3) Field level validation: shows error next to all fields, that validation failed for

BusinessException describes an error within a business process.

Add BusinessException to corresponding VersionAwareResponseService.

    @Override

            BusinessComponent bc) {
        if (data.isFieldChanged(MyExampleDTO_.customField)) {

            }
            entity.setCustomField(data.getCustomField());

        return new ActionResultDTO<>(entityToDto(bc, entity));
    }

            BusinessComponent bc) {
        if (data.isFieldChanged(MyExampleDTO_.customField)) {

                throw new Exception("Error");
            } catch (Exception e) {
                throw new RuntimeException("An unexpected error has occurred.");
            }
        }

        return new ActionResultDTO<>(entityToDto(bc, entity));
    }

                .newAction()
                .action("save", "save")

Create сustom service for business logic check.

Use if:

Business logic check required for fields

Step 1 Create сustom method for check.

    private void validateFields(BusinessComponent bc, MyExampleDTO dto) {
        BusinessError.Entity entity = new BusinessError.Entity(bc);
        if (Boolean.FALSE.equals(dto.getCustomField())) {
            entity.addField(MyExampleDTO_.customField.getName(), "The field 'customField' can contain only 'True");
        }
        if (Boolean.FALSE.equals(dto.getCustomFieldAdditional())) {
            entity.addField(
                    MyExampleDTO_.customFieldAdditional.getName(),
                    "The field 'customFieldAdditional' can contain only 'True"
            );
        }
        if (entity.getFields().size() > 0) {
                throw new BusinessException().setEntity(entity);
        }
    }

Step 2 Add сustom method for check to corresponding VersionAwareResponseService.

    @Override
    protected ActionResultDTO<MyExampleDTO> doUpdateEntity(MyEntity entity, MyExampleDTO data,
            BusinessComponent bc) {
        validateFields(bc, data);
        if (data.isFieldChanged(MyExampleDTO_.customFieldAdditional)) {
            entity.setCustomFieldAdditional(data.getCustomFieldAdditional());
        }
        if (data.isFieldChanged(MyExampleDTO_.customField)) {
            entity.setCustomField(data.getCustomField());
        }

        return new ActionResultDTO<>(entityToDto(bc, entity));
    }
