Bug 363674

Description darren 2011-11-14 02:20:12 EST

I have an @Embeddable with a @OneToOne relationship:

@Embeddable
public class GreenStar_ implements Serializable, IGreenStar
{
    private GreenStarOfficeProject officeProject;

    @OneToOne(fetch= FetchType.LAZY)
    public GreenStarOfficeProject getOfficeProject() {
        return officeProject;
    }

Which is used as:

@Entity
public class GreenStarActivity extends Activity implements IGreenStarElement
{
    private GreenStar_ greenStar;
    @Embedded
    public GreenStar_ getGreenStar() {
        return greenStar;
    }

   public GreenStarActivity(Element owner, GreenStarOfficeProject officeProject, String name) {
       super(owner, officeProject, name);
       greenStar = new GreenStar_(officeProject);
       init();
   }

When getOfficeProject() is accessed in the following transient method in a GreenStarActivity it returns as null (although it was clearly already set):

    @Transient
    @Override
    public boolean isPassed() {
        String $i = "isPassed";        
        boolean test = true;
        resetFailures();         
        if (getGreenStar()==null) {
            log_error($i,"getGreenStar()==null");
        }
        else if (getGreenStar().getOfficeProject()==null) { 
            log_error($i,"getGreenStar().getOfficeProject()==null");
        }
        BooleanValue redevelopment = getGreenStar().getOfficeProject().getV893_refurbishment_redevelopment();

I get a NullPointerException on trying to access a getter within the null OfficeProject object above.
(I can tell it is null already from the verbose logging, and the GreenStar_ object is clearly not null.)

However this works fine when the default FetchType.EAGER is used, it only fails for LAZY.

And it only occurs on the relationship within the @Embeddable.
