Hello there,
how on earth can this happen?!?

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
