| EmbeddedObjects - fields not populated correctly [message #670009] |

We have just moved over from toplink to eclipselink, and none of our embedded objects are being correctly populated on calls to em.find() (maybe others to). When debugging I can see that the correctly populated object has been returned from the db (and is in a cache?), but when building / copying/ cloning that object to return to the caller of em.find() it is failing to pull the value out of that object into the returned object. It appears that in here
(org.eclipse.persistence.internal.descriptors.PersistenceObjectAttributeAccessor.getAttributeValueFromObject(Object) ):
public Object getAttributeValueFromObject(Object object) {
return ((PersistenceObject)object)._persistence_get(this.attributeName);
}
the object passed in is the object containing the embedded object, yet this.attributeName is name of the field in the embedded object - in this case 'value' and returns null as there is no attribute named 'value' in the object passed in. I can only see that it would work if the embedded object itself was passed in, or if the attribute name was name of the embedded object.
in the calling method next down the stack frame the direct to field mapping is org.eclipse.persistence.mappings.DirectToFieldMapping[value- - >WSSDBA.WBR_USER.ACHOLLOOKUPONLY].
Something is not quite right with the weaving or something elseewhere, has anyone seen anything similar ?
Eclipselink 2.2.0.
I am trying to reproduce this is a standalone app/ ear but not having much look reproducing in such a scenario.
Thanks

I'll try without the weaving / newer version of eclipselink in while, prob next week...
in the meantime :
the mapped superclass at the top of the heirarchy
@MappedSuperclass
public class UserTahoe extends TahoeEntity implements CloneAccessor, Serializable{
private static final long serialVersionUID = 3875580327768987028L;
@Transient
private String oprIDTransient;
etc
private String areaUnit = " ";
@ManyToOne(fetch=FetchType.LAZY)
@JoinColumn(name="PORTFOLIO",insertable=false,updatable=false)
private Portfolio portfolio;
@Column(name="PORTFOLIO")
private String portfolioId ;
etc
@Embedded
@AttributeOverride(name="value", column=@Column(name="ACHOLLOOKUPONLY"))
private JpaBoolean acHolLookupOnly = new JpaBoolean(false) ;
@Embedded
@AttributeOverride(name="value", column=@Column(name="SUPERVISOR"))
private JpaBoolean supervisor = new JpaBoolean(false) ;
@Embedded
@AttributeOverride(name="value", column=@Column(name="BANKMANAGER"))
private JpaBoolean bankManager = new JpaBoolean(false) ;
the @Entity itself
@Entity
@Table(name="WBR_USER")
public class User extends UserTahoe implements Serializable, LiveFieldAccess, StatusFieldAccess {
etc
the embedded object
@Embeddable
public class JpaBoolean implements Serializable {
private static final long serialVersionUID = -8018836031372234990L ;
/** Value for use in query parameters to match true */
public static final String TRUE = "1";
/** Value for use in query parameters to match false */
public static final String FALSE = "0";
private String value;
