I believe you both, but my problem is

(a) far as I remember, I create my EOs using EOUtilities.createAndInsertInstance, exclusively;

(b) since my memory is not reliable, I've used grep, and there's not one "new DBRecord" nor "new DBAuction" in my whole project

Actually the (very probably, can't be entirely sure from the log) offending DBRecord has been logged out shortly before the NPE, with null PK (for it was newly created, which makes sense), and... a non-null EC.

That all said, of course it is still possible I've got either a DBRecord or its related DBAuction with null EC due to some strange bug, but darn, it's weird :-O

Thanks a lot,

The _DBRecord thing is one of the pretty old legacy parts, standard EO code as generated in an Eclipse project by its eogenerator, as it used to work a couple of years ago when I used Eclipse the last time:

===

  public static final ERXKey<model.DBAuction> AUCTION = new ERXKey<model.DBAuction>("auction");

...

  public static final String AUCTION_KEY = AUCTION.key();

...

  public model.DBAuction auction() {

    (model.DBAuction)storedValueForKey(_DBRecord.AUCTION_KEY) // <== line 61

  }

===

The relationship should be nonempty, but even if it was empty, it should simply return null from storedValueForKey, and not NPE?!? :-O

Thanks for any insight,

OC
