Can anyone explain why I'm getting this error? Basically when I have save
an object to the database if I attempt to update it and then save it I get

something?

This looks like an optimistic locking error - i.e., the object updated has
been updated in the database by another process since you last fetched it
in your process. This has nothing to do with locking an editing context.
So what do i do to clear it? I don't think there are any other processes
running but then I'm not sure so how do I debug this problem? The problem
only seems to happen when I save something and then go back to edit it and
try to save it again. To eliminate it I have to rebuild the application and
then the same thing happens again.
