[jboss-user] [EJB 3.0] - New Core bug? FetchType.Eager does not work on collection w

[JLuv]

I'm trying to eagerly load a Set of an entity that has an EmbeddedId.  When I call EntityManager.find, it does not load the Set.  When I change the embeddedId to be a regular Id, all is well.  Am I doing something wrong, or should I log a new bug?

I'm using Entity Manager 3.2.0 CR2, with Hibernate Core 3.2.0 CR4.

Card:

  | @Entity
  | public class Card implements Serializable {
  | 	@Id
  | 	private String id;
  | 
  | 	@OneToMany(cascade = CascadeType.ALL, fetch = FetchType.EAGER, mappedBy = "card")
  | 	private Set<CardField> fields;
  | 
  | 	public Card(String id) {
  | 		this();
  | 		this.id = id;
  | 		
  | 	}
  | 
  | 	Card() {
  | 		fields = new HashSet<CardField>();
  | 	}
  | 
  | 	public String getId() {
  | 		return id;
  | 	}
  | 
  | 	public void setId(String id) {
  | 		this.id = id;
  | 	}
  | 
  | 	public void addField(Card card, Key key) {
  | 		fields.add(new CardField(card, key));
  | 	}
  | 
  | 	@Override
  | 	public int hashCode() {
  | 		final int PRIME = 31;
  | 		int result = 1;
  | 		result = PRIME * result + ((id == null) ? 0 : id.hashCode());
  | 		return result;
  | 	}
  | 
  | 	@Override
  | 	public boolean equals(Object obj) {
  | 		System.out.println("Equals invoked");
  | 		System.exit(0);
  | 		if (this == obj)
  | 			return true;
  | 		if (obj == null)
  | 			return false;
  | 		if (getClass() != obj.getClass())
  | 			return false;
  | 		final Card other = (Card) obj;
  | 		if (id == null) {
  | 			if (other.id != null)
  | 				return false;
  | 		} else if (!id.equals(other.id))
  | 			return false;
  | 		return true;
  | 	}
  | }
  | 

CardField:

  | @Entity
  | public class CardField implements Serializable {
  | 
  | 	private static final long serialVersionUID = 1L;
  | 	
  | 	private PrimaryKey primaryKey;
  | 
  | 	private String id;
  | 
  | 	CardField(Card card, Key key) {
  | 		this.primaryKey = new PrimaryKey(card, key);
  | 	}
  | 
  | 	CardField() {
  | 	}
  | 
  | 	@Override
  | 	public int hashCode() {
  | 		final int PRIME = 31;
  | 		int result = 1;
  | 		result = PRIME * result + ((primaryKey == null) ? 0 : primaryKey.hashCode());
  | 		return result;
  | 	}
  | 
  | 	@Override
  | 	public boolean equals(Object obj) {
  | 		System.out.println("Equals invoked");
  | 		System.exit(0);
  | 		if (this == obj)
  | 			return true;
  | 		if (obj == null)
  | 			return false;
  | 		if (getClass() != obj.getClass())
  | 			return false;
  | 		final CardField other = (CardField) obj;
  | 		if (primaryKey == null) {
  | 			if (other.primaryKey != null)
  | 				return false;
  | 		} else if (!primaryKey.equals(other.primaryKey))
  | 			return false;
  | 		return true;
  | 	}
  | 
  | 	@EmbeddedId
  | 	public PrimaryKey getPrimaryKey() {
  | 		return primaryKey;
  | 	}
  | 
  | 	public void setPrimaryKey(PrimaryKey primaryKey) {
  | 		this.primaryKey = primaryKey;
  | 	}
  | 
  | 	// BEGIN Workaround until issue is resolved. 
  | 	// http://opensource.atlassian.com/projects/hibernate/browse/EJB-225
  | 	@ManyToOne
  | 	@JoinColumn(insertable=false, updatable=false)
  | 	public Card getCard() {
  | 		return primaryKey.getCard();
  | 	}
  | 
  | 	public void setCard(Card card) {
  | 		primaryKey.setCard(card);
  | 	}
  | 
  | 	@ManyToOne
  | 	@JoinColumn(insertable=false, updatable=false)
  | 	public Key getKey() {
  | 		return primaryKey.getKey();
  | 	}
  | 
  | 	public void setKey(Key key) {
  | 		primaryKey.setKey(key);
  | 	}
  | 	// END Workaround
  | }
  | 

Changing CardField to use regular Id makes the Set in Card load eagerly:

  | @Entity
  | public class CardField implements Serializable {
  | 
  | 	private static final long serialVersionUID = 1L;
  | 	
  | 	private PrimaryKey primaryKey;
  | 
  | 	private String id;
  | 
  | 	private Card card;
  | 
  | 	private Key key;
  | 
  | 	CardField(Card card, Key key) {
  | 		this.primaryKey = new PrimaryKey(card, key);
  | 		this.card = card;
  | 		this.key = key;
  | 		this.id = card.getId() + key.getId();
  | 	}
  | 
  | 	CardField() {
  | 	}
  | 
  | 	@Override
  | 	public int hashCode() {
  | 		final int PRIME = 31;
  | 		int result = 1;
  | 		result = PRIME * result + ((primaryKey == null) ? 0 : primaryKey.hashCode());
  | 		return result;
  | 	}
  | 
  | 	@Override
  | 	public boolean equals(Object obj) {
  | 		System.out.println("Equals invoked");
  | 		System.exit(0);
  | 		if (this == obj)
  | 			return true;
  | 		if (obj == null)
  | 			return false;
  | 		if (getClass() != obj.getClass())
  | 			return false;
  | 		final CardField other = (CardField) obj;
  | 		if (primaryKey == null) {
  | 			if (other.primaryKey != null)
  | 				return false;
  | 		} else if (!primaryKey.equals(other.primaryKey))
  | 			return false;
  | 		return true;
  | 	}
  | 
  | 	//@EmbeddedId
  | 	@Transient
  | 	public PrimaryKey getPrimaryKey() {
  | 		return primaryKey;
  | 	}
  | 
  | 	public void setPrimaryKey(PrimaryKey primaryKey) {
  | 		this.primaryKey = primaryKey;
  | 	}
  | 
  | 	@Id
  | 	public String getId() {
  | 		return id;
  | 	}
  | 
  | 	public void setId(String id) {
  | 		this.id = id;
  | 	}
  | 
  | 	@ManyToOne(optional = false)
  | 	@JoinColumn(name="cardId")
  | 	public Card getCard() {
  | 		return card;
  | 	}
  | 
  | 	public void setCard(Card card) {
  | 		this.card = card;
  | 	}
  | 
  | 	@ManyToOne(optional = false)
  | 	@JoinColumn(name="keyId")
  | 	public Key getKey() {
  | 		return key;
  | 	}
  | 
  | 	public void setKey(Key key) {
  | 		this.key = key;
  | 	}
  | }
