Hello,
I have two models loaded from the same uri (a UML file) with two different
ResourceSet.
How may I "compare" model elements of these two models. I mean, as model elements
belong to two distinct resources, I can't use the equal operator.
Element aElement; // (resource is A from ResourceSet RA)
Element bElement; // (resource is B from ResourceSet RB)
// I would like to do
if (aElement == bElement)
thanks.

Hi, François,
Equivalent instances in two resource sets should have the same URI.
So, try:
EcoreUtil.getURI(aElement).equals(EcoreUtil.getURI(bElement) )
Of course, elements only have URIs if they are actually in resources, but I
assume that's already the case. Also, you may need to normalize the URIs
before comparing them if your resource sets have different URI mappings.
