Environment

• Platform version: 7.2.15

Description of the bug or enhancement

Steps:

1. Create a new project
2. Create a new screen

3. Add to screen SuggestionPickerField (can use code example from below)

   @Inject
   private SuggestionPickerField<NewEntity> suggest;
   @Inject
   private Metadata metadata;
   
   @Subscribe
   public void onInit(InitEvent event) {
       NewEntity entity1 = metadata.create(NewEntity.class);
       entity1.setName("entity1");
       NewEntity entity2 = metadata.create(NewEntity.class);
       entity2.setName("entity2");
       List<NewEntity> entityList = Arrays.asList(entity1,entity2);
       suggest.setSearchExecutor((searchString, searchParams) -> {
           return entityList.stream().filter(entity -> entity.getName().contains(searchString)).collect(Collectors.toList());
       });
   }
   
   @Install(to = "suggest", subject = "optionIconProvider")
   private String suggestOptionIconProvider(NewEntity newEntity) {
       if (newEntity == null) {
           return null;
       }
       if ("entity1".equals(newEntity.getName())) {
           return CubaIcon.ADDRESS_BOOK.source();
       } else if ("entity2".equals(newEntity.getName())) {
           return CubaIcon.BLACK_TIE.source();
       }
       return null;
   }

4. Run the app
5. Open created screen
6. Pass entity name in SugestionPickerField and pick it

ER:

• Icons should be installed for the entities in the search field
• Icons should be shown for suggestions in the dropdown list

AR: Icons haven't been installed in the search field and don't show in the dropdown list

Icons should be shown for suggestions in the dropdown list

After investigation it turns out that SuggestionField has custom popup widget and it does not provide the ability to set icons by design.
