Example
Step1 Add String field to corresponding BaseEntity.
@Entity
@Getter
@Setter
@NoArgsConstructor
public class MyEntity extends BaseEntity {
@Column
private String customField;
}
Step2 Add field String to corresponding DataResponseDTO.
@Getter
@Setter
@NoArgsConstructor
public class MyExampleDTO extends DataResponseDTO {
@SearchParameter(name = "customField")
private String customField;
public MyExampleDTO(MyEntity entity) {
this.id = entity.getId().toString();
this.customField = entity.getCustomField();
}
}
Step3 Add to .widget.json.

Placeholder
Placeholder
allows you to provide a concise hint, guiding users on the expected value. This hint is displayed before any user input. It can be calculated based on business logic of application.

Step 1 Add custom field for color
to corresponding DataResponseDTO. The field can contain a HEX color or be null.
@Getter

@NoArgsConstructor
public class MyExampleDTO extends DataResponseDTO {
@SearchParameter(name = "customField")
private String customField;
private String customFieldColor;
public MyExampleDTO(MyEntity entity) {
this.id = entity.getId().toString();
this.customField = entity.getCustomField();
this.customFieldColor = "#edaa";
}
}
Step 2 Add "bgColorKey" : custom field for color
to .widget.json.
Step 2 Add "bgColorKey" : custom field for color

Example
Step1 Add mapping DTO->entity to corresponding VersionAwareResponseService.
@Override
protected ActionResultDTO<MyExampleDTO> doUpdateEntity(MyEntity entity, MyExampleDTO data,
BusinessComponent bc) {
if (data.isFieldChanged(org.demo.documentation.fields.text.basic.MyExampleDTO_.customField)) {
entity.setCustomField(data.getCustomField());
}
return new ActionResultDTO<>(entityToDto(bc, entity));
}
@Override
public void buildRowDependentMeta(RowDependentFieldsMeta<MyExampleDTO> fields, InnerBcDescription bcDescription,
Long id, Long parentId) {
fields.setEnabled(MyExampleDTO_.customField);
}
Works for List.

Works for Form.
Option 1 Enabled by default.
@Override
public void buildRowDependentMeta(RowDependentFieldsMeta<MyExampleDTO> fields, InnerBcDescription bcDescription,
Long id, Long parentId) {
//
}
Not recommended.
Property fields.setDisabled() overrides the enabled field if you use after property fields.setEnabled.
Works for List.
Works for Info.
Works for Form.
Filtering
Filtering
allows you to search data based on criteria.
For MyExample field
filtering is case-insensitive and retrieves records containing the specified value at any position (similar to SQL Like %value%
).

private String customField;
public MyExampleDTO(MyEntity entity) {

Drilldown
DrillDown
allows you to navigate to another view by simply tapping on it. Target view and other drill-down parts can be calculated based on business logic of application
Also, it optionally allows you to filter data on target view before it will be opened see more

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

RuntimeException
describes technical error within a business process.
Add RuntimeException to corresponding VersionAwareResponseService.
@Override
protected ActionResultDTO<MyExampleDTO> doUpdateEntity(MyEntity entity, MyExampleDTO data,

if (data.isFieldChanged(MyExampleDTO_.customField)) {
entity.setCustomField(data.getCustomField());

@NoArgsConstructor
public class MyExampleDTO extends DataResponseDTO {
@SearchParameter(name = "customField")
@Pattern(regexp = "[A-Za-z]+", message = ONLY_LETTER)

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 (!String.valueOf(dto.getCustomField()).matches("[A-Za-z]+")) {
entity.addField(MyExampleDTO_.customField.getName(), "The field 'customField' can contain only letters.");
}
if (!String.valueOf(dto.getCustomFieldAdditional()).matches("[A-Za-z]+")) {
entity.addField(
MyExampleDTO_.customFieldAdditional.getName(),
"The field 'customFieldAdditional' can contain only letters."
);
}
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));
}

Sorting
allows you to sort data in ascending or descending order.
MyExample field
is a text field, so lexicographic sorting is used for it
