Hi Team,
I am new in the forum and a newbie in Prosysopc, so please tell me if the information I give is incomplete/not clear. Also I would like to add an image to make it clearer but I cannot find the way. In Opc Expert I would like to show the folder tree in the left frame. It works perfectly when I first receive the data from the server. So far so good, by contrast when I modify the name of the folder on the server, the folder has still the same name in the client, and their tags are appended to the already existing entries. Also, a new folder with the data of the old one and the name of the new one is created. I am using MyNodeManager(extends NodeManagerUaNode).

The code is the following:

private FolderTypeNode myObjectsFolder;
private UaObjectNode myDevice;
final UaObject objectsFolder = getNodeManagerTable().getNodeManagerRoot().getObjectsFolder();
myObjectsFolder = createInstance(FolderTypeNode.class, “MyObjects”, myObjectsFolderId);
this.addNodeAndReference(objectsFolder, myObjectsFolder, Identifiers.Organizes);

final NodeId myDeviceId = new NodeId(ns, “MyDevice”);
myDevice = new UaObjectNode(this, myDeviceId, “MyDevice”, Locale.ENGLISH);
myObjectsFolder.addReference(myDevice, Identifiers.HasComponent, false);

QualifiedName deviceQualifiedName = new QualifiedName(getNamespaceIndex(), devicePath);
NodeId deviceId = new NodeId(getNamespaceIndex(), “MyLevel”);
UaNode myLevel = new UaObjectNode(this, deviceId, deviceQualifiedName, new LocalizedText(devicePath, Locale.ENGLISH));

if(!getNodeManagerTable().hasNode(myLevelId)) {
myDevice.addComponent(myLevel);
}

Does anyone have an idea what is happening and how to fix the issue?
Thanks and regards.
