OK so we think we probably screwed up implementing MultiLockManager
somehow, so heres a couple of more questions to make sure all of our
bases are covered :
In Session's sleep we have ( terminate looks exactly the same except
of course its for terminate )
public void sleep()
try {
synchronized (ecLockManager) {
if (ecLockManager().isLocked()) {
ecLockManager().unlock();
}
}
}
finally {
super.sleep();
}
}
Should we be using unregisterEditingContext instead of unlock() ? If
not why/when should you use unregisterEditingContext ?

Perhaps a parent ec? Is there any child ecs involved here?
I don't recall terribly clearly now as it's been a while... but I
remember that for some strange reason an object that I had in the
shared editing context didn't localize into the ec that I wanted
when attempting to set the relationship - but there was no
exception until saveChanges. It might have been when said ec
didn't have its sharedEc == null, or invalid locking or something.
I recall, when trying to track it down, mucking around with
temporarily unlocking shared ec locks and stuff. But I think it
turned out to be ensuring that the ec in question didn't properly
set its shared ec to null (I think).
Sorry I don't recall much more than that.
Ah, there you go on about the shared EC again. :-P
Someone says it can't/shouldn't be used... just can't help
myself... Shared ec, VI, ... I'm just waiting for the next
suggestion :-)
I had not considered the SEC being involved. That puts a new twist
on things.
Owen, are you using the SEC?
Bear in mind that you *might* be using it unintentionally. e.g.,
you've declared in your model 'share objects' and/or you're not
nullifying your ec's shared ec (which is the usual for your default
session context IIRC).
with regards,
