I'm trying to use CRUD-add-on with Vaadin 14. But when I try to run this view:
@Route("configuration")
@JsModule("./styles/shared-styles.js")
@CssImport("./styles/views/main/main-view.css")
public class ConfigurationView extends AppLayout {
/**
*
*/
private static final long serialVersionUID = 1L;
public ConfigurationView(YoloObjectService yoloObjectService, ObjectNameService objectNameService) {
System.out.println(yoloObjectService == null);
System.out.println(objectNameService == null);
// crud instance
GridCrud<YoloObjectEntity> crud = new GridCrud<>(YoloObjectEntity.class);
// grid configuration
crud.getGrid().setColumns("email", "active", "objectName", "threshold");
crud.getGrid().setColumnReorderingAllowed(true);
// form configuration
crud.getCrudFormFactory().setUseBeanValidation(true);
crud.getCrudFormFactory().setVisibleProperties("email", "active", "threshold", "objectName");
crud.getCrudFormFactory().setFieldProvider("objectName", new ComboBoxProvider<>("Object Name", objectNameService.findAll(), new TextRenderer<>(ObjectNameEntity::getName), ObjectNameEntity::getName));
// layout configuration
setContent(crud);
crud.setFindAllOperationVisible(false);
// logic configuration
crud.setOperations(() -> yoloObjectService.findAll(),
user -> yoloObjectService.save(user),
user -> yoloObjectService.save(user),
user -> yoloObjectService.delete(user)
);
}
}
I get this error because of crud.getCrudFormFactory().setUseBeanValidation(true); above.

Reproduce issue:
To reproduce the issue, run the project and then go to http://localhost:8080 then to the configuration tab and press + sign. Now you will have two errors about Bean Validation.

Question:
How can I find this Bean Validator?
