Hello Andreas,

Can you provide the stack trace from the debugger where you noticed the
  ObjectBuilder.buildRow was called on the EmailPart
ObjectBuilder/Descriptor?  Short of reproducing it locally, that might
show the code path taken and point to how the wrong
objectbuilder/descriptor is getting used.  If you are able to debug
further, I'd go back from that point and see how that ObjectBuilder was
looked up.

 

I think I'm on to something.

 

This is where UnitOfWorkChangeSet.cloneToObjectChangeSet is populated with the wrong ObjectChangeSet:

 

public ObjectChangeSet findOrCreateLocalObjectChangeSet(Object entityClone, ClassDescriptor descriptor, boolean isNew){
    ObjectChangeSet changes = (ObjectChangeSet)this.getObjectChangeSetForClone(entityClone);
    if (changes == null) {
        if (descriptor.isAggregateDescriptor()) {
            changes = new AggregateObjectChangeSet(CacheId.EMPTY, descriptor, entityClone, this, isNew);
        } else {
            changes = new ObjectChangeSet(descriptor.getObjectBuilder().extractPrimaryKeyFromObject(entityClone, session), descriptor, entityClone, this, isNew);
        }
        changes.setIsAggregate(descriptor.isDescriptorTypeAggregate());
        this.addObjectChangeSetForIdentity(changes, entityClone);
    }
    return changes;
}

The value of the descriptor is:

 

RelationalDescriptor(no.officenet.origo.email.domain.model.entities.EmailPart --> [DatabaseTable(origo_email_part)])

 

and not EmailSinglePart as I would expect.

 

I need to figure out why the descriptor sometimes is of the correct type when adding to the same collection (EmailMessage.rootPartList).
