Hi,
We have a model, stored in EMFStore, at the root of the ECPProject. In it we have a certain EObject that has a non-containment EReference with an EClass reference type. When we try to add an EClass that comes from a platform ecore, we get the following IndexOutOfBoundsException:
!ENTRY org.eclipse.emf.emfstore.common.model 2 2 2014-07-08 16:13:31.274

Would anybody have a clear idea as to why this is happening? I could give more information tomorrow morning (EST here); I'm just not sure what kind of information would be helpful here.
Thanks very much for your help.
Regards,
Olivier
EDIT: just noticed I missed a few important lines from the stack trace. Notice the addCutElement() call.

Hi,
thanks for pointing this out. I agree, that it should probably be part
of the SDK, could you open a BR for this, plz?
Best Regards

Done. BR: https://bugs.eclipse.org/bugs/show_bug.cgi?id=439349
And I apologize for not getting back with my test results yesterday. It so happens this was the solution to our problem, adding the org.eclipse.emf.emfstore.ecore plugin to our target platform.
Regards,
Olivier
