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
