Hi Scott,
sorry for the delay once again, but we had a holiday in Germany last
week, right after EclipseCon ;).
I've looked into the problem by now but couldn't reproduce it yet.
It seems to me as if this problem can only occur if the project state
for the precendent version on the server becomes corrupt.
Does this error appear right after you've shared the project or after
your first commit? Is it reproducable?
Do you mind sharing your server/client workspace with us, that contains
the project that can not be committed? By default, the workspace is
located in the .emfstore folder of your home directory.
Thanks for your valueable help so far.
Edgar

OK, thanks for trying. My model has only one unusual aspect that has
bitten me whenever I write generic EMF utilities. You may have noticed
that I have what I call 'uplinks' --- bi-directional references from a
contained EObject up to its parent. This allows for type-safe traversal
up the EMF containment hierarchy vs. using eContainer() with casts. I've
found that the notifications generated with such uplinks need special
handling in some cases.

I have reproduced it twice, but haven't found the specific combination
of activities that make it happen. So, no, it's not yet reproducible.

I'd be happy to share the client and server workspaces with you when the
checksums recur again. The last time the problem occurred I waited for a
few days thinking I would hear back from you asking for it, but I
couldn't wait on my testing anymore.

Could you try to provoke a conflict that involves modifying such
bidirectional links? Let's suppose you have a base version where element
A is contained in container B.
Client 1 moves A to a new container instance C and commits.
Client 2 removes A from B and tries to commit.
We had a issues with bidirectional references in the past, which should
be fixed by now, but it's possible that we've missed something.
Regards,
Edgar
