That's correct (with <p> being inside an <h:column> of course).

Do you mean UIData#setValue? In that case, the JavaDoc for
UIData#setValue does not have to change.

We could create a MapDataModel indeed, but we can also just pass
((Map) current).entrySet() into IterableDataModel.
E.g. in Mojarra:
// ..
} else if (current instanceof Iterable) {
setDataModel(new IterableDataModel<>((Iterable<?>) current));
} else if (current instance Map) {
setDataModel(new IterableDataModel<>(((Map) current).entrySet() );
}
Kind regards,
