JPAContainer and FieldFactory ComboBox sorting

Flow
1

Hello, I have a simple ComboBox presenting a list of entities, which is backed by JPAContainer.
When I use this ComboBox “normally” by adding it to a layout, the entity sorting is working properly:

MunicipalitySelector    homeMunicipality    = new MunicipalitySelector("Municipality");

addComponent(homeMunicipality);

Homever, this is not the case when building the form (for a Person entity) automatically with FieldFactory:

setSingleSelectType(Municipality.class, MunicipalitySelector.class);


The entities are always sorted by their id’s and the sorting property is ignored.

I am defining the sorting this way in the ComboBox:

JPAContainer<Municipality> container = JPAContainerFactory.make(Municipality.class, Application.PERSISTENCE_UNIT);
container.setApplyFiltersImmediately(false);
container.sort(new String[] { Municipality.NAME }, new boolean[]
 { true });

setConverter(new SingleSelectConverter<Municipality>(this));
setContainerDataSource(container);

        for (Object id : container.getItemIds()) {
            Municipality m = container.getItem(id).getEntity();
            setItemCaption(id, m.getName());
        }

The Municipality entity is linked to a Person entity via @ManyToOne(fetch = FetchType.LAZY), using EclipseLink.

Can this have something to do with FieldFactory’s way of instantiating a .newInstance() of the selector? I have debugged the selector code and made sure container.sort() is executed, but somehow it’s still suspicious.

Or can it be a bug in FieldFactory somehow overriding the container sorting?

Thanks for your time!

For anyone’s future reference, the culprit was FieldFactory overriding select container, which caused most settings to be lost:

    protected Field createManyToOneField(EntityContainer containerForProperty, Object itemId, Object propertyId, Component uiContext) {
        Class<?> type = containerForProperty.getType(propertyId);
        JPAContainer container = createJPAContainerFor(containerForProperty, type, false);

        AbstractSelect nativeSelect = constructReferenceSelect(containerForProperty, itemId, propertyId, uiContext, type);
        nativeSelect.setMultiSelect(false);
        nativeSelect.setCaption(DefaultFieldFactory.createCaptionByPropertyId(propertyId));
        nativeSelect.setItemCaptionMode(NativeSelect.ITEM_CAPTION_MODE_ITEM);
        [b]
nativeSelect.setContainerDataSource(container);
[/b]
        nativeSelect.setConverter(new SingleSelectConverter(nativeSelect));
        return nativeSelect;
    }
