arghhh... pressed the wrong button.
Yes, thats what I mean. For every page that does data manipulation I
use a child editing context.
Why a child instead of a peer? To me, using a child seems to be the
wrong thing to do. That may well be causing this problem if the user
back tracks or a validation exception is thrown.
Ok.
Are you creating your own editing contexts? If so, how are you
locking and unlocking them? Are you calling undo() or revert() on
the editing context? Is your application running out of memory?
I use ERXEC, so I dont have to care about locking, or should I?
No, not if your properties are set correctly. But you did not say so I
had to ask. :-)
er.extensions.ERXEC.safeLocking=true
If I do data manipulation / saveChanges, I only do it this way:
In constructor:
ecSession = (ERXEC) session().defaultEditingContext();
ecDetail = (ERXEC) ERXEC.newEditingContext(ecSession);
I'd just make that
ecDetail = (ERXEC) ERXEC.newEditingContext();
I tried that and it seems to work.
On save:
synchronized (LOCK) {
ecDetail.saveChanges();
ecSession.saveChanges();
}
No catch for save failures?
Yes, there is some try/catch around this.
So many thanks, this editing context thing really seems to work. :)
Cheers
Michael
