Hi,

I've created two entity classes and a composite primary key class. I think I have all three coded properly but when I deploy with Seam 1.1.6 I get an exception:
AnnotationException: com.abc.selfEnrollment.RecordDataKey has no persistent id property

I'm sure I doing something silly. Please tell me what. Here are relevant sections from each class:

@Entity
@Name("record")
@Scope(SESSION)
@Table(name = "record")
public class Record implements Serializable {

 private Long recordId;
 private Long agreementProductId;
 private Date createDate;
 private Date modifiedDate;
 private Date eventDate;
 private Long participantId;
 private Long recordStatusCode;
 private Long appUserId;
 private Collection<RecordData> recordData;

 public Record() {
 }

 @Id
 @GeneratedValue
 public Long getRecordId() {
 return recordId;
 }

 public void setRecordId(Long recordId) {
 this.recordId = recordId;
 }

 @OneToMany(cascade = CascadeType.ALL, mappedBy = "record")
 public Collection<RecordData> getRecordData() {
 return recordData;
 }

 public void setRecordData(Collection<RecordData> recordDatas) {
 this.recordData = recordDatas;
 }
 ...
 }

@IdClass(com.abc.selfEnrollment.RecordDataKey.class)
@Entity
@Name("recordData")
@Scope(SESSION)
@Table(name = "record_data")
public class RecordData implements Serializable {

 private Long recordId;
 private Long biomarkerId;
 private Record record;
 private Double value;
 private Long uomId;

 public RecordData() {
 }

 @Id
 public Long getBiomarkerId() {
 return biomarkerId;
 }

 public void setBiomarkerId(Long biomarkerId) {
 this.biomarkerId = biomarkerId;
 }

 @Id
 @Column(name = "ORDERID", nullable = false, insertable = false, updatable = false)
 public Long getRecordId() {
 return recordId;
 }

 public void setRecordId(Long recordId) {
 this.recordId = recordId;
 }

 @ManyToOne
 @JoinColumn(name = "RECORD_ID")
 public Record getRecord() {
 return record;
 }

 public void setRecord(Record record) {
 this.record = record;
 }
 ...
 }

public final class RecordDataKey implements Serializable {

 public Long recordId;
 public Long biomarkerId;

 public RecordDataKey() {
 }

 public RecordDataKey(Long orderId, Long itemId) {
 this.recordId = orderId;
 this.biomarkerId = itemId;
 }

 public boolean equals(Object otherOb) {
 if (this == otherOb) {
 return true;
 }
 if (!(otherOb instanceof RecordDataKey)) {
 return false;
 }
 RecordDataKey other = (RecordDataKey) otherOb;
 return ((recordId == null ? other.recordId == null : recordId
 .equals(other.recordId)) && (biomarkerId == other.biomarkerId));
 }

 public int hashCode() {
 return ((recordId == null ? 0 : recordId.hashCode()) ^ ((int) biomarkerId
 .longValue() >>> 32));
 }

 public String toString() {
 return "" + recordId + "-" + biomarkerId;
 }
}
