| [eclipselink-users] EmbeddedObjects - fields not populated correctly |
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.
