This may not be considered an issue; I'll point it out while I'm remembering. When generating named queries for the
following entity, seems like there should be

    @NamedQuery(name = "Aspectdisplay.findByPK", query =
        "SELECT d FROM Aspectdisplay d WHERE d.chevPK = :pk")})

Of course I think you can also do
    em.find(Aspectdisplay, pk)



public class Aspectdisplay implements Serializable {
    private static final long serialVersionUID = 1L;
    @EmbeddedId
    protected ChevPK chevPK;
    ...

@Embeddable
public class ChevPK implements Serializable {
    @Basic(optional = false)
    @Column(name = "CHART_ID", nullable = false)
    private int chartId;
    @Basic(optional = false)
    @Column(name = "EVENT_ID", nullable = false)
    private int eventId;
    ...
