Thanks Amadeo, but I ended up creating a method that looks like this. It would
be nice to get some feedback on it, if I’m violating any Cayenne Commandments.
/**
* @return An existing object or fault if registered with the OC,
otherwise creates a new hollow object based on the given ObjectId.
*/
public static Persistent faultForObjectId( ObjectContext oc, ObjectId
objectId ) {
Persistent object = (Persistent) oc.getGraphManager().getNode(
objectId );
if( object == null ) {
ClassDescriptor descriptor =
oc.getEntityResolver().getClassDescriptor(objectId.getEntityName());
object = (Persistent) descriptor.createObject();
object.setPersistenceState(PersistenceState.HOLLOW);
object.setObjectContext(oc);
object.setObjectId(objectId);
oc.getGraphManager().registerNode(objectId, object);
}
return object;
}
Cheers,
