Binding components to nonpersisted entities

Support
#1

What is the best practice to binding components to nonpersisted (in memory) entities? Possibly an ArrayList of the nonpersisted entity and then loading that into DataContainer via a loader. My only requirements is have collection passed to a screen and bind to a component on Init.

Hello @fredzim1

You can install DataLoader delegate to provide data, for example:

@Inject
private Metadata metadata;

@Install(to = "testEntitiesDl", target = Target.DATA_LOADER)
private List<TestEntity> testEntitiesDlLoadDelegate(LoadContext<TestEntity> loadContext) {
    List<TestEntity> entities = new ArrayList<>();

    for (int i = 0; i < 10; i++) {
        TestEntity entity = metadata.create(TestEntity.class);

        entity.setFirstName("First name #" + (i + 1));
        entity.setLastName("Last name #" + (i + 1));
        entity.setPhone("8 800 555 35 35");

        entities.add(entity);
    }

    return entities;
}
