I use these types to get padding and comfort. It doesnt make sense to me.
Sorry to keep posting. Just trying to click and go.
What could be causing an NPE?
@Entity
@ClassDescriptor(hasCyclicRelationships = true)
@BeanModels(
{ @BeanModel(pageType = PageType.LIST,
include = "player, gp, g, a, pts, ppg",
exclude="") })
public class PlayerStats extends AbstractEntity implements Cloneable,
Serializable {
public Integer getPts() {
return getA() + getG(); // offending line
}
Caused by:
java.lang.NullPointerException
