- Thread-topic: saveChanges() not saving
I have come across a
rather strange problem. Changes to an EO are not saving
properly. In memory it shows that I have changed the EO but when I look at
the editingContext, it doesn't show it in _unprocessedChanges. It also
doesn't save the change that I am making. I finally realized that if I
call ec.committedSnapshotForObject(ecr); BEFORE I make any changes to the
object, it works fine.
Here's an example of
the code:
EOEditingContext ec
= new EOEditingContext();
// If I
uncomment this, it saves properly.
//
ec.committedSnapshotForObject(ecr);
EmailCommunicationRecipient ecr =
(EmailCommunicationRecipient)EOUtilities.faultWithPrimaryKeyValue(ec, "EmailCommunicationRecipient", new
Integer(11312312));
ecr.setDateSent(new
NSTimestamp());
ec.saveChanges();
Strangely, if I do
the following, the dateSent won't save but the status will:
EOEditingContext ec
= new EOEditingContext();
EmailCommunicationRecipient ecr =
(EmailCommunicationRecipient)EOUtilities.faultWithPrimaryKeyValue(ec, "EmailCommunicationRecipient", new
Integer(11312312));
ecr.setDateSent(new NSTimestamp());
ec.committedSnapshotForObject(ecr);
addObjectToBothSidesOfRelationshipWithKey(aValue,
"toCurrentStatus");
ec.saveChanges();
The only thing
special with EMailCommunicationRecipient is that it is a single table inhertance
in the model.
EMailCommunicationRecipient extends CommunicationRecipient which extends
AbstractCommunicationRecipient.
Until I figure out
what's going on, I was going to just add the following (because I just
don't know how many places this is happening). Will this add much
overhead?:
public void awakeFromFetch(EOEditingContext
ec){
super.awakeFromFetch(ec);
ec.committedSnapshotForObject(ecr);
}
Thanks,
David
