Let's consider this use case:
{code:java}@Embeddable
class Component {
private String component;
public Component() {
}
private Component(String component) {
this.component = component;
}
public String getComponent() {
return component;
}
public void setComponent(String component) {
this.component = component;
}
}
@Entity(name = "CardGame")
class CardGame {
private String id;
private Component firstPlayerToken;
public CardGame() {
}
private CardGame(String id, String name) {
this.id = id;
this.name = name;
this.firstPlayerToken = createEmbeddedValue( name );
}
@Id
public String getId() {
return id;
}
public void setId(String id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
this.firstPlayerToken = createEmbeddedValue( name );
}
@Embedded
public Component getFirstPlayerToken() {
return firstPlayerToken;
}
public void setFirstPlayerToken(Component firstPlayerToken) {
this.firstPlayerToken = firstPlayerToken;
}
private Component createEmbeddedValue(String name) {
return new Component( name + " first player token" );
}
}
}{code}
When we enable the inline dirty checking enhancement and create the entity, the dynamic field $$_hibernate_compositeOwners is null. If we put the embedded annoation on the field, it is initialized with the value "firstPlayerToken".
The update of the embedded field hasn’t any effect too.
I don't think the behaviour should be different in these cases but I might be wrong. |
