Bummer. I was kind of hoping you'd come up with something involving parts of the EOF that I am not that familiar with. Hm, do you know perhaps of a way to simply turn optimistic locking off in EOF, so that last write always wins?

Of course, the obvious solution to this would be to turn off locking on all database columns in EOModeler, but with JC this does not help. It seems that the locking column is simply ignored, and the column values are checked anyway (well, I am not sure what is happening, but I have a test case in which an update conflict exception is thrown when editing a record whose entity has no columns marked as locked). I forgot to mention that before, sorry.


You could try the documentation. :-P

Did that already... Since it is the EODistributionContext that throws the exception, that is where I started. However, even though it deals with this, it's public API and docs don't even mention update conflicts. Nor does the delegate. So, seeing that you didn't come up with some lower level EOF magic, I would not know where to look. But, I will browse some more in the JC distribution classes. Maybe something there deals with this... I don't think it does though, I've read most of the docs for that stuff and don't recall update conflicts ever being mentioned.


However, seeing that WOJC explicitly deals with update conflicts, it would be reasonable to assume that it is possible to gracefully resolve them. That assumption by itself isn't worth much though :)

Will dig a bit more.

So far, this has resulted in nothing.
