Hello,
Hopefully this is easy and I’m just forgetting to do something, but I haven’t found examples in the documentation or Jmix UI Samples app.
This issue I’m running into is that I can’t seem to get any result other than detached entity objects when implementing the UIComponents bean to create a RadioButtonGroup or CheckboxGroup component.
I have an instance name set for my SurveyAnswerOption class, and I’ve tried expanding the fetchPlan to use streams from a collection container, as well as using a service instead of a collection container to pull a list of entities directly. In both of these attempts, I’m setting the list of options using RadioButtonGroup.setItems() or CheckboxGroup.setItems(). Anything I can think to try produces a detached visual representation of the entities to select from.
This Jmix 2.0 entity detail view builds components dynamically based off of a SurveyQuestion class.
Commented out lines are examples of what I have also tried:
View controller:
private void buildRadioButtonGroup(SurveyQuestion surveyQuestion) {
RadioButtonGroup radioButtonGroup = uiComponents.create(RadioButtonGroup.class);
radioButtonGroup.setId(String.valueOf(surveyQuestion.getId()));
radioButtonGroup.setLabel(surveyQuestion.getQuestionText());
radioButtonGroup.setRequired(true);
// radioButtonGroup.setItems(getAnswerOptions(surveyQuestion));
radioButtonGroup.setItems(surveyAnswerOptionsDc.getItems());
form.add(radioButtonGroup);
}
private List<SurveyAnswerOption> getAnswerOptions(SurveyQuestion surveyQuestion) {
return surveyResponseService.getAnswerOptions(surveyQuestion);
// return surveyAnswerOptionsDc.getItems()
// .stream().filter(answerOption -> surveyQuestion.equals(answerOption.getSurveyQuestion()))
// .sorted(Comparator.comparing(SurveyAnswerOption::getDisplayOrder))
// .collect(Collectors.toList());
}
Service class:
@Service
@Transactional
public class SurveyResponseService {
@Autowired
private DataManager dataManager;
private static final String GET_ANSWER_OPTIONS = "select e from SurveyAnswerOption e where e.surveyQuestion = :surveyQuestion order by e.displayOrder";
public List<SurveyAnswerOption> getAnswerOptions(SurveyQuestion surveyQuestion) {
return dataManager.load(SurveyAnswerOption.class)
.query(GET_ANSWER_OPTIONS)
.parameter("surveyQuestion", surveyQuestion)
.fetchPlan("_base")
.list();
}
}
View descriptor fetch plan:
<collection id="surveyAnswerOptionsDc" class="com.company.survey.entity.SurveyAnswerOption">
<fetchPlan extends="_base"/>
<loader id="surveyAnswerOptionsDl">
<query>
<![CDATA[select e from SurveyAnswerOption e]]>
</query>
</loader>
</collection>
