Buggy source:
private void buildQuestion(Questionnaire questionnaire,GroupComponent group,Profile profile,ProfileStructureComponent structure,ElementComponent element,String path) throws Exception {
  group.setLinkIdSimple(path);
  group.setTextSimple(element.getDefinition().getShortSimple());
  group.setRequiredSimple(element.getDefinition().getMin().getValue() > 0);
  group.setRepeatsSimple(!element.getDefinition().getMax().getValue().equals("String_Node_Str"));
  if (Utilities.noString(element.getDefinition().getCommentsSimple()))   ToolingExtensions.addFlyOver(group,element.getDefinition().getFormalSimple() + "String_Node_Str" + element.getDefinition().getCommentsSimple());
 else   ToolingExtensions.addFlyOver(group,element.getDefinition().getFormalSimple());
  if (!element.getDefinition().getType().isEmpty() || element.getDefinition().getType().get(0).getCodeSimple().equals("String_Node_Str")) {

      sub.setTextSimple(t.getTag("String_Node_Str"));
      processDataType(questionnaire,profile,sub,element,element.getPathSimple() + "String_Node_Str" + t.getTag("String_Node_Str"),t);
    }
  }
 else   processDataType(questionnaire,profile,group,element,element.getPathSimple(),element.getDefinition().getType().get(0));
}

Fixed version (ground truth):
private void buildQuestion(Questionnaire questionnaire,GroupComponent group,Profile profile,ProfileStructureComponent structure,ElementComponent element,String path) throws Exception {
  group.setLinkIdSimple(path);
  group.setTextSimple(element.getDefinition().getShortSimple());
  group.setRequiredSimple(element.getDefinition().getMin().getValue() > 0);
  group.setRepeatsSimple(!element.getDefinition().getMax().getValue().equals("String_Node_Str"));
  if (Utilities.noString(element.getDefinition().getCommentsSimple()))   ToolingExtensions.addFlyOver(group,element.getDefinition().getFormalSimple() + "String_Node_Str" + element.getDefinition().getCommentsSimple());
 else   ToolingExtensions.addFlyOver(group,element.getDefinition().getFormalSimple());
  if (element.getDefinition().getType().size() > 1 || element.getDefinition().getType().get(0).getCodeSimple().equals("String_Node_Str")) {
    QuestionComponent q=addQuestion(group,AnswerFormat.choice,element.getPathSimple(),"String_Node_Str","String_Node_Str");
    List<TypeRefComponent> types=expandTypeList(element.getDefinition().getType());
    q.setOptions(makeTypeList(questionnaire,profile,types,element.getPathSimple()));
    for (    TypeRefComponent t : types) {
      GroupComponent sub=q.addGroup();
      sub.setLinkIdSimple(element.getPathSimple() + "String_Node_Str" + t.getTag("String_Node_Str"));
      sub.setTextSimple(t.getTag("String_Node_Str"));
      processDataType(questionnaire,profile,sub,element,element.getPathSimple() + "String_Node_Str" + t.getTag("String_Node_Str"),t);
    }
  }
 else   processDataType(questionnaire,profile,group,element,element.getPathSimple(),element.getDefinition().getType().get(0));
