> I have found that using auditReader.find() to retrieve audit information for entities containing embedded components with default values. This is a regression issue (also occurs in 1.2.2.GA release of Envers - Hibernate 3.3 compatible, but did not occur not in 1.2.1 GA) that started occurring since HHH-3957.
> Sample entity and embeddable:
> {code:title=DefaultValueComponentTestEntity.java|borderStyle=solid}
> @Id
> @GeneratedValue
> private Integer id;
> @Embedded
> @Audited
> @AttributeOverrides( { @AttributeOverride(name = "comp2.str1", column = @Column(name = "COMP2_STR1")) })
> private DefaultValueComponent1 comp1 = null;
> {code}
> {code:title=DefaultValueComponent1.java|borderStyle=solid}
> private String str1;
> @Embedded
> private DefaultValueComponent2 comp2 = new DefaultValueComponent2();
> {code}
> {code:title=DefaultValueComponent2.java|borderStyle=solid}
> private String str1 = "defaultValue";
> private String str2;
> {code}
> When I try to persist an instance of DefaultValueComponentTestEntity, with comp1 = null and subsequently call auditReader.find(), an instance is returned where:
> {noformat} "defaultValue".equals(comp1.comp2.str1){noformat}
> (using java bean notation for simplicity).
> I will attach a complete testcase.
