That makes me wonder about whether you are using containment
references. It's very important that every object as eResource() !=
null. Without that, you'll get exceptions while saving and these
dangling references will disappear.

You say "contain" nested elements, but I'll bet the reference isn't
marked as a containment reference, i.e., EReference.containment == true....

It sounds like you simply intended it to be a containment reference but
didn't mark it that way in the model...
