OK -
I still haven't figured this error out. I can write a new record.
But when I try to edit the record I get the error?!
It is calling the same submit method, etc.
Model looks fine. A new field column was added to the Sybase db.
Basically, it seems as though the new
field/attribute is causing the grief
Any other thoughts?
An external type is wrong or missing, a prototype is wrong or missing,
the model contains invalid or out of date jdbc2info.

wo version?
wonder/version?
did you diff your model? what changed? do any of your changes
look suspicious?

The old app does write without the exception. It uses the same
model, adaptor, etc.
The new app crashes upon:
currentObject.editingContext().saveChanges();
Thoughts?
Thanks

James,
What are you doing when this occurs?
Do other operations work?

How do I debug this error. I have never seen it before. I am
working with SYBASE as the database. Is this the jdbc adaptor
issue?
thanks
