[news.eclipse.tools.emf] Re: [CDO] Duplicate ID problem ? Can a CDO mode

["Simon McDuff" <smcduff@xxxxxxxxxxx>]

I`ve created a testcase and the fix that we`ve created for the problem 
mention in th bugs 248915 fixed your problem. So it was really the same 
things.

I added your testcase as well  I will attach it to the bug in a few minutes 
:
https://bugs.eclipse.org/bugs/show_bug.cgi?id=248915

My patch will probably not go in since it is incomplete (other stuff is 
missing) few things could change based on our discussion....
Meanwhile you can use my patch!! :-)
