I ran into another snag using EMFStore. Here's my scenario:
First, I create a new project.
Second, I load my model instance from local disk using the standard EMF
XMI Resource.
Next, I add the contents of this Resource (a single root EObject) to the
EMFStore project modelElements list.
Finally, when I attempt to share my local project on the EMFStore server
I get the following error on the server console. What are possible
causes of this?

Hi Scott,
thank you for your report! Is it possible that you changed one of the
generated getters or setters or the generated factory? This could be the
reason for a new object being created during deserialization (and hence
this object has no ID).
If this is not the case:
Is it possible to share the model plugin and/or the Ecore with us?
Could you share the code snippet that loads the resource and puts its
contents into the project?
Hope this helps!
Cheers,
Maximilian

Maximilian,
I made no changes to the ID generation --- I'm using the out of the box
ID generator.
I made some progress debugging this problem using a simpler test case
outside of my application. It turns out that ordering of the operations
in my scenario matters. If the model instance is added to EMFStore's
model element list *before* the local project is shared, the exception
occurs.
On the other hand, if my model instance is added *after* sharing the
local project, no problem. I haven't tested beyond this, but wanted to
give you this update and get your thoughts.
Is this expected behavior for EMFStore?
I'll look into creating a standalone test case.
Scott

Maximilian,
Here's a test case that replicates the issue. It's based on your
HelloWorld example code as a base. If a model element is added to the
local project before it is shared AND that model element is part of an
EMF Resource, then problem occurs.
Hope this helps. Is there a workaround I can use?
Scott

Hi Scott,
thanks for the test case and sorry for the delay (we're are currently
attending EclipseCon). We'll integrate a test case like this in our test
suite, since apparently it was missing. We also do have a fix ready and
will look at the other issues you reported as soon as possible.
We're planning to do a hotfix release addressing the reported issues at
the end of next week.
Cheers,
Edgar

Scott,
thank you very much for the test case. A work around would be to remove

Cheers,
Maximilian
