I would check out "Subclass Missing Primary Key" on http://
en.wikibooks.org/wiki/Programming:WebObjects/EOF/Using_EOF/
Common_Pitfalls_and_Troubleshooting and see if this might be related.

Hi all,
In an application that has been working great for a long time,
suddenly I am getting this error:
[2006-07-13 11:19:22 CEST] <WorkerThread1>
java.lang.NullPointerException
at com.webobjects.eoaccess.EOUtilities.primaryKeyForObject
(EOUtilities.java:834)
at Customer.custID(Customer.java:46)
at EditCustomer.saveChanges(EditCustomer.java:94)
This is when the Customer class is attempting to get the Primary
Key for the current record.
On further investigation I have realised that the Customer object
is not being saved at all, it appears as though it is unable to get
a Primary Key for the record as it saves it. The EO_PK_TABLE
appears fine and all other tables save with no problem.
I wonder does anyone have any idea where I should look to find the
problem, I have checked everything and it all looks as it did before.
Kind regards,
David.
