How to compare two UML Model Resources ignoring XMI ids. [message #1733998]

When I copy an UML Model Resource using EcoreUtil.copyAll all XMI:IDs are redefined. Then, if I use diffmerge to compare them the result is that the models are completely different. I've tryed to use the MatchCriterionKind.NAME in the ConfigurableMatchPolicy, however it haven't worked.

You need to override method 'getUniqueName(...)' in your match policy in order to make MatchCriterionKind.NAME effective on your metamodel (in this case, UML2).
Alternatively, since org.eclipse.uml2.uml.NamedElement also has a 'getQualifiedName()' method, you may directly override method 'getMatchID(...)' and use the qualified name as a match ID for named elements.
