Steps to reproduce : 
	1/ Create a model with 2 classes and an Association between these classes
	2/ Copy your model and delete the Association
	3/ Compare the UML files : 
	    You get the message : "Navigable UML Association has been added"
	4/ Select this message -> you get the following exception : 
java.lang.UnsupportedOperationException

I think it has been corrected since the Indigo release. Which version did you try with?

Regards,

Vincent,

This problem only arises with the "old" org.eclipse.emf.compare.diff.extension example. Either close the project or delete it : the UML specific comparison engine is what you should be using.

You are right, it's a version problem. Its works with your nightly build.
