MappedSuperclass

[Armando Flores Ibarra]

 First of all, I need to say that any of these classes can be changed.

Here is my situation:

- He have an abstract class named BaseLocation annotated with @MappedSuperclass

- BaseLocation has a Country (@ManyToOne) and a StateProvinceCode (@ManyToOne)

- SiteDetail class extends from BaseLocation

- Location class extends from BaseLocation

- SiteDetail has a Location (@ManyToOne)


QSiteDetail qSiteDetail = QSiteDetail.siteDetail;

This works:

qSiteDetail.country.[any Country field]
qsiteDetail.stateProvinceCode.[any StateProvinceCode field]

But this doesn't:

If we try to do this, we get a NullPointerException because both country and stateProvinceCode are null

qSiteDetail.location.country.[any Country field]
qsiteDetail.location.stateProvinceCode.[any StateProvinceCode field]


Any help would be really appreciated.

Thank you.
