Hi,
I encountered com.webobjects.eoaccess.EOGeneralAdaptorException when
saveChanges() after inserting an enterprise object into editing
context.
It only happens when I set a relationship of the inserted object.
Without setting the relationship, my app run smoothly.
The inserted entity called Sale. And the problematic relationship
called referenceSale, which joins to sale.
(If a sale has a referenceSale, it will retrieve the value of property
from referenceSale instead of itself.)
Sale:
Column | Type |
Modifiers
------------------+-----------------------------+------------------------------------------------
saleid | bigint | not null default
nextval('sale_seq'::regclass)
clientid | bigint | not null
storeid | bigint |
referencesaleid | bigint |
... other property
Foreign-key constraints:
"sale_client_fk" FOREIGN KEY (clientid) REFERENCES
client(clientid) DEFERRABLE INITIALLY DEFERRED
"sale_store_fk" FOREIGN KEY (storeid) REFERENCES store(storeid)
DEFERRABLE INITIALLY DEFERRED
"sale_referencesale_fk" FOREIGN KEY (referencesaleid) REFERENCES
sale(saleid) DEFERRABLE INITIALLY DEFERRED
I have no idea why this relationship will cause the problem. Searching
on list, I turned on the SQL logging and see there is a
NullPointerException.
No SQL generated. What can I do to investigate this problem further?
