-------------------------------------
Another use case:
@Embedded
private UtilEmbeddable emb;
@Embedded
@AttributeOverrides({
@AttributeOverride(name="embedField",
colu...@column(name="embedField2")),
})
private UtilEmbeddable emb1;
pu.isLoaded( e, "emb.embedField"); << embedField column
pu.isLoaded( e, "emb1.embedField"); << embedField2 column
> Provider/Persistence*Util.isLoaded for Embeddable fields

> Key: OPENJPA-1430
> URL: https://issues.apache.org/jira/browse/OPENJPA-1430
> Project: OpenJPA
> Issue Type: New Feature
> Components: jpa
> Affects Versions: 2.0.0
> Reporter: Albert Lee
>
> JPA 2.0 spec describe the isLoaded semantics for embeddable in Section 3.2.9
> Load State.
> However it does not define how embeddable field can be specified in the
> isLoaded methods.
> E.g.
> @Entity Class Entity {
> @Embedded Embeddable emb;
> }
> @Embeddable Class Embeddable {
> int embedField;
> }
> Entity e;
> PersistenceUtil pu;
> pu.isLoaded( e, "emb"); <<<< defined
> pu.isLoaded( e, "emb.embedField"); <<<< new feature
