[StatusException] Cannot lookup index without a namespace ta

[marklendering]

Hello,

Im having some issues when parsing ExtensionObjects. The exception message is not very clear what the problem is, and debugging the code doesnt show anything weird either.


The exceptions occurs in the following block of code on the "GenericEncodeableObject genericEncodeableObject = mgr.ParseValue(v);" line.

Code: Select all

                    GenericStructureDataType d;
                    DataValue dv = parseStructuredObjectTypes(session, nodeId, out d);
                    DataTypeManager mgr;
                    getDataTypeManager(session, out mgr);
                    if (dv.Value != null)
                    {
                        List<KeyValue> keyValueList = new List<KeyValue>();
                        List<GenericEncodeableObject> genericObjectList = new List<GenericEncodeableObject>();
                        ExtensionObject[] extObjArray = dv.WrappedValue.ToExtensionObjectArray();
                        foreach (ExtensionObject v in extObjArray)
                        {
                            GenericEncodeableObject genericEncodeableObject = mgr.ParseValue(v);
                            genericObjectList.Add(genericEncodeableObject);
                            if (!genericEncodeableObject[0].ToString().Equals(""))
                            {
                                KeyValue kv = new KeyValue();
                                kv.key = genericEncodeableObject[0].ToString();
                                kv.index = genericEncodeableObject[1].ToInt32();
                                kv.value = genericEncodeableObject[2].ToString();
                                kv.typeId = genericEncodeableObject[3].ToInt32();
                                keyValueList.Add(kv);
                            }
                        }
                        varObj.selectableVariableData.keyValues = keyValueList.ToArray();
                        varObj.selectableVariableData.genericObjects = genericObjectList.ToArray();
                        count = keyValueList.Count;
                        errorCode = error.OK;
                    }

the exception is as follows:

Code: Select all

Do you have any idea what the problem might be here?
