Error (C# client for Content Server Web Services)

Bibek Adhikari

Hi,
When i tried to fetch version of a document from live link i encountered an exception showing that "LLUnknownFieldException: LLValue unknown field name: FileAttributes".

    private int ConcreteFetchVersion(int VolumeID, int NodeID, int VersionID, BinaryWriter outputStream, int tryNumber)
    {
        int status;
        private LAPI_DOCUMENTS _documents;
        private LLSession _llsession;
        try
        {
            lock (_llsession)
            {
                lock (_documents)
                {
                    status = _documents.FetchVersion(VolumeID, NodeID, VersionID, outputStream);
                }
            }
            return status;
        }
        catch (LLUnknownFieldException llUnknownFieldException)
        {
            LogERError("Error in Fetch Version of item '{0}', version '{1}'",
                objectId, versionId, llUnknownFieldException);
            if (string.Compare(llUnknownFieldException.getMessage(),
                "LLValue unknown field name: FileAttributes", true) == 0)
            {
                errorMessage = "File not available";
            }
            throw;
        } 
        catch (Exception ex)
        {    
            Log.WriteLine(LogLevel.Low, LogName,
               "Failed retrieving Fetch Version; VolumeID : {0}, NodeID : {1}, VersionID : {2}", VolumeID, NodeID,VersionID, ex);
            throw;
        }
    }

Any suggestions and improvement with be much appreciated. I could not identify here the root cause of the issue, and how to process it further. Thanks in advance.

Bibek, can you give us more context? From a glance at the code, I'd have to guess you were writing a C# client for Content Server Web Services, but I'm not sure. Can you clarify?

(If that is your environment, the very first thing I'd do is make sure you used the .wsdl corresponding to the version of CS/CWS you have deployed. Second, I'd re-tag the question. )
