I’m trying to expose to the client a definition for a complex type in my server.
I have created a new DataType node under DataTypes/Structure called PersonType, and a new DataItemType node at DataTypes/XML Schema/My Types/PersonXMLType, that I’m going to use to define the XML data. I need to create a node called “Default XML” that ties these two nodes together. The PersonType node will have a HasEncoding reference to Default XML, and Default XML will have a HasDescription reference to PersonXMLType. Default XML also needs a HasTypeDefinition reference to DataTypeEncodingType. So the references should be something like this:

PersonType
—– HasEncoding ———
V
Default XML ——– HasTypeDefinition ———–> DataTypeEncodingType
|
V—– HasDescription —–
PersonXMLType

Here’s the code I’m using to create the Default XML node:
final NodeId defXmlNodeId = new NodeId(namespaceIndex, “Default XML PersonType”);
QualifiedName defXmlBrowseName = new QualifiedName(namespaceIndex, “Default XML”);
LocalizedText defXmlDisplayName = new LocalizedText(“Default XML”, (Locale)null);
UaNode defXmlNode = nodeFactory.createNode(NodeClass.Object, defXmlNodeId,
defXmlBrowseName, defXmlDisplayName);
personTypeNode.addReference(defXmlNodeId, Identifiers.HasEncoding, false);
defXmlNode.addReference(dataTypeEncodingType, Identifiers.HasTypeDefinition, false);
defXmlNode.addReference(personXmlTypeNode, Identifiers.HasDescription, false);

After creating the references above, if I use a client to browse to the PersonType node, I’m getting an error BadNodeIdUnknown. I can see the PersonTypeNode in the tree, but It seems like maybe the Default XML node doesn’t really stick around, and so the HasEncoding reference is broken. Do I need to do something else when adding this node?
