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An external type is wrong or missing, a prototype is wrong or missing, the model contains invalid or out of date jdbc2info.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?

OK -
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
