Hi,
We have recently moved from eclipse 3.6 to eclipse 4.2.2.

We are facing some problem during Undo action on few elements with following trace:

Caused by: java.lang.IllegalArgumentException: The 'no duplicates' constraint is violated
at org.eclipse.emf.common.util.AbstractEList.add(Unknown Source)
at org.eclipse.emf.common.util.ECollections.setEList(Unknown Source)
at org.eclipse.emf.ecore.change.impl.FeatureChangeImpl.process(Unknown Source)
at org.eclipse.emf.ecore.change.impl.FeatureChangeImpl.apply(Unknown Source)

at org.eclipse.emf.workspace.AbstractEMFOperation.doUndo(Unknown Source)
at org.eclipse.emf.workspace.CompositeEMFOperation.doUndo(Unknown Source)
... 80 more

Is this a known issue ?
As this was working fine with previous eclipse version, will like to know if there has been a change in this area and we need to do something to make this work ?
I do see a bugzilla related to undo, Can this be the cause of it ?

Which version of EMF were you using? 2.6?

A Papyrus bug. Is you're problem related to using Papyrus?

Sarika,

I can't tell you what's wrong from just your stack trace. It's also odd
that everything has unknown source as if there was no debug information;
all our builds include debug information.
Which version of EMF are you moving to?

Hi,
Our product RSA (Rational Software Architect) has now moved to Ecore 2.8 now.
I am not working on eclipse build directly. Any thing else I can provide to understand the problem better ?

Sorry, but it's not possible to diagnose the problem just from the stack
trace.
