Thanks!

[I had originally posted this over at Model->UML but Ecore Tools seems to be the right place to ask.]
Greetings!
I am able to add nodes to an EMF model generated from XSD:
EPackage ep = poClass.getEPackage();
EClass ctNew = (EClass) ep.getEClassifier("ChangeType");
EObject ctObject = ep.getEFactoryInstance().create(ctNew);
ctObject.eSet(ctObject.eClass().getEStructuralFeature("comment "), "...");
I am also able to add a node to a single-valued feature:
EClass cltNew = (EClass) ep.getEClassifier("ChangeLogType");
clt = ep.getEFactoryInstance().create(cltNew);
po.eSet(poClass.getEStructuralFeature("changeLog"), clt);
I can also obtain the list of change entries under the many-values change node:
EList<EObject> changes = clt.eClass().getEStructuralFeature("change").eContents();
Here is my problem:
changes.add(ctObject);
gives
Caused by: java.lang.UnsupportedOperationException
at org.eclipse.emf.ecore.util.EContentsEList$FeatureIteratorImp l.add(EContentsEList.java:779)
at java.util.AbstractSequentialList.add(Unknown Source)
at java.util.AbstractList.add(Unknown Source)
which I had planned to use as follows:
clt.eSet(clt.eClass().getEStructuralFeature("changeType"), changes);
Is there a way to add child nodes using the reflective API of EMF?
I need to avoid using specific types of the generated model in this section of code, since this code should be usable by multiple separate generated models.
Thanks in advance for any advice.
