Hi,

Is there a way to add objects to a many EReference without using copy?
When doing this, my objects are not added to the containment.

EList<EObject> manyReferenceCollection = (EList<EObject>)
target.eGet(eReference);

manyReferenceCollection.add(objectToSet);

target.eSet(eReference, manyReferenceCollection);

When creating a copy first , it works but my objects are copies, not the
original objects.

EList<EObject> manyReferenceCollection = (EList<EObject>)
target.eGet(eReference);

Collection<EObject> copyAll =
EcoreUtil.copyAll(manyReferenceCollection);

copyAll.add(objectToSet);

target.eSet(eReference, copyAll);

I need the orginal objects to be set back into the reference, as
elsewhere I keep an index of these objects. The index breaks if a copy
of the original list is stored back in the reference.

Thank You
Christophe
