[jboss-jira] [JBoss JIRA] Commented: (HIBERNATE-50) Embedded Objects get set to null if all its members are null
[ http://jira.jboss.com/jira/browse/HIBERNATE-50?page=comments#action_12409114 ]
Paolo Dona commented on HIBERNATE-50:
-------------------------------------
I just came across this issue, and I agree with marcinko. I'm using @Embedded for
Money objects like this:
@Entity
class Activity {
@Embedded private Money cost = new Money();
public Money getCost(){return cost;}
public void setCost(Money newCost){ self.cost = newCost;}
}
@Embeddable
class Money {
private BigDecimal amount;
private Currecy currency;
// getters/setters omitted
}
And I'm always getting NPEs even if I initialize it to new Money(). This is really
annoying.
Is there at least a someway clean workaround for this?
Embedded Objects get set to null if all its members are null

Key: HIBERNATE-50
URL: http://jira.jboss.com/jira/browse/HIBERNATE-50
Project: Hibernate
Issue Type: Bug
Environment: WinXP SP2, JBoss 4.0.4 GA as well as JBoss 4.0.5 GA, installation
profile ejb3
Reporter: milan w?lke
Assigned To: Steve Ebersole
When having an embedded object only containing members of non-simple-types (e.g. String)
and fetching it with the entity manager the following happens:
If all columns, the embedded objects values are based on, are null the embedded object
itself is set to null even if a non-arg-constructor set it to a non-null value before. A
valid workaround is to include a member of a simple-type (e.g. int) in the embedded
object. Doing this not all the values can be set to null, which results in not setting the
embedded object itself to null, too.
