Do you have a code example? I can't seem to get this to work... I have existing Connection profile, which is index 1, and try to set it like this:
System.Xml.XmlDocument xdoc = new System.Xml.XmlDocument();
System.Xml.XmlElement[] elem = new System.Xml.XmlElement[2];
System.Xml.XmlElement xel = xdoc.CreateElement("coreNodeId");
xel.InnerText = nodeID.ToString();
elem[0] = xel;
xel = xdoc.CreateElement("ConnectionProfile");
xel.InnerText = ConnectionProfile.ToString();
elem[1] = xel;
System.Xml.XmlElement result = orion.Invoke("Cirrus.Nodes", "UpdateSelectedNodeColumns", elem);
This doesn't seem to work?
