[jboss-jira] [JBoss JIRA] Commented: (HIBERNATE-50) Embedded Objects get set to null if all its members are null

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?

> 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.
