Example
Option1
One will usually use Long, Double or BigDecimal java types in DTO and Entity for storing this field type.
Next example shows Long usage: Step1 Add Double field to corresponding DataResponseDTO.
@Getter
@Setter
@NoArgsConstructor
public class MyExampleDTO extends DataResponseDTO {
@SearchParameter(name = "customField", provider = BigDecimalValueProvider.class)
private Double customField;
public MyExampleDTO(MyEntity entity) {
this.id = entity.getId().toString();
this.customField = entity.getCustomField();
}
}
@Entity
@Getter
@Setter
@NoArgsConstructor
public class MyEntity extends BaseEntity {
@Column
private Double customField;
}
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

Add fields.setPlaceholder to corresponding FieldMetaBuilder.
@Override
public void buildRowDependentMeta(RowDependentFieldsMeta<MyExampleDTO> fields, InnerBcDescription bcDescription,
Long id, Long parentId) {
fields.setEnabled(MyExampleDTO_.customField);
fields.setPlaceholder(MyExampleDTO_.customField, "100000.00");
}

Example
Step 1 Add custom field for color to corresponding DataResponseDTO. The field can contain a HEX color or be null.
@Getter
@Setter
@NoArgsConstructor
public class MyExampleDTO extends DataResponseDTO {
@SearchParameter(name = "customField", provider = BigDecimalValueProvider.class)
private Double 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.

Example
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);
}
@Override
public void buildIndependentMeta(FieldsMeta<MyExampleDTO> fields, InnerBcDescription bcDescription, Long parentId) {
if (configuration.getForceActiveEnabled()) {
fields.setForceActive(MyExampleDTO_.customField);
}
fields.enableFilter(MyExampleDTO_.customField);
}
}

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. Search uses equals (=) operator.

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 DrillDown

Option 1
Step 1 Add fields.setDrilldown to corresponding FieldMetaBuilder.
@Override
public void buildRowDependentMeta(RowDependentFieldsMeta<MyExampleDTO> fields, InnerBcDescription bcDescription,

fields.setEnabled(MyExampleDTO_.customField);
fields.setDrilldown(
MyExampleDTO_.customField,
DrillDownType.INNER,
"/screen/myexample/view/myexampleform/" + PlatformMyExampleController.myExampleBc + "/" + id
);
}
Step 2 Add "drillDown": "true" to .widget.json.
{
"name": "MyExampleList",
"title": "List title",
"type": "List",
"bc": "myExampleBc",
"fields": [
{

}
custom field to .widget.json. See more Drilldown
Step 2 Add "drillDown": "true" to .widget.json.
{
"name": "MyExampleInfo",
"title": "Info title",
"type": "Info",
"bc": "myExampleBc",
"fields": [
{
"label": "Custom Field",

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.
3) Field level validation: shows error next to all fields, that validation failed for
Option 1:

BusinessException describes an error within a business process.
Add BusinessException to corresponding VersionAwareResponseService.
@Override
protected ActionResultDTO<MyExampleDTO> doUpdateEntity(MyEntity entity, MyExampleDTO data,
BusinessComponent bc) {
if (data.isFieldChanged(MyExampleDTO_.customField)) {
if (data.getCustomField() < 100000) {
throw new BusinessException().addPopup(LESS_100000);
}
entity.setCustomField(data.getCustomField());
}
return new ActionResultDTO<>(entityToDto(bc, entity));
}
Works for List.

Works for Form.
RuntimeException describes technical error within a business process.
Add RuntimeException to corresponding VersionAwareResponseService.
@Override
protected ActionResultDTO<MyExampleDTO> doUpdateEntity(MyEntity entity, MyExampleDTO data,
BusinessComponent bc) {
if (data.isFieldChanged(MyExampleDTO_.customField)) {
try {
//call custom function
throw new Exception("Error");
} catch (Exception e) {
throw new RuntimeException("An unexpected error has occurred.");

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 (dto.getCustomField() < 100000) {
entity.addField(MyExampleDTO_.customField.getName(), "The field 'customField' cannot be less than 100 000.00");
}
if (dto.getCustomField() < 100000) {
entity.addField(
MyExampleDTO_.customFieldAdditional.getName(),
"The field 'customFieldAdditional' cannot be less than 100 000.00"
);
}
if (entity.getFields().size() > 0) {
throw new BusinessException().setEntity(entity);
}
}
Step 2 Add сustom method for check to corresponding VersionAwareResponseService.
