Thanks Chuck. Some digging in the model and cleanup in the plists
solved the problem, and I have *no* idea why. *sigh*. Sometimes I
wish sold books - or grew flowers or something for a living... ;)

My only guess is that the model got corrupted or something even
stranger happened. :-) Take a look in .plist file.

Good morning folks.
I'm experiencing some weird validation behaviour.
I just generated a DB schema from an old EOModel using WOLips. When
I attempt to saveChanges() into a table using some rather vanilla
code, I get NullPropertyExceptions for every attribute (even though
the attributes all allow nulls in both the model and the DB (except
the PK, of course).
I'm using WO 5.4.1, FrontBase, and yesterday's Wonder nightly.
The code:
SWUser u = new SWUser();
someEC.insertObject( user );
someEC.saveChanges();
The error (excerpt, I get one of these for each attribute in the
EOM):
<er.extensions.ERXValidationException object:
<is.karlmenn.soloweb.data.SWUser pk:"null">; propertyKey:
telephone; type: NullPropertyException; additionalExceptions:
( )> )>
The stack trace (below my code):

Look familiar? Would anyone care to shed some light in my direction?
