Please log a bug for this. I will probably come upon this issue sometime, too.

I am unsure however if this is because of the way I construct the XML or if this is a bug in Muse. The SimpleNotificationProducer publish array method does the following: NotificationMessage message = createNotificationMessage(); for (int n = 0; n < content.length; ++n) message.addMessageContent(content[n]); and in SimpleNotificationMessage the addMessageContent does the following: if (content == null) throw new NullPointerException(_MESSAGES.get("NullMessageContent")); QName name = XmlUtils.getElementQName(content); _messageContent.put(name, content); but _messageContent is a LinkedHashMap, and from what the Java specification says adding multiple instances with the same key overwrites the values. So only the last one will be preserved. I have solved the issue for the moment by wrapping the Elements that represent the array in another top level element that gets published.
