could there be something wrong here:

ERXCopyable.copyLogger.debug("Removing objects in to-many relationship " + relationshipName);
for (ERXCopyable relatedObject : relatedObjects) {
	destination.removeObjectFromBothSidesOfRelationshipWithKey(relatedObject, relationshipName);
	if (relatedObject.isNewObject()) {
		editingContext.deleteObject(relatedObject);
	}
}

at this point in the process I get:

I do not understand the code that starts the for loop. from what to what?

java.util.NoSuchElementException
