    // AOSRunMode::client - this method is always called on the client, which eliminates the need for a CAS assert.
public static client DocuValue writeDocuValue(DocuRef  docuRef, Filename filename = '', BinData binData = null)

        docuValue.Path = ''; //path is already stored in ArchivePath in docuType or docuParameters

    if (docuType.FilePlace == DocuFilePlace::Database)
    {
        // Insert to database
        if (WinAPI::fileLocked(filename))
        {
            info("@SYS72783",'',SysInfoAction_Formrun::newFormnameControlnameDesc(formstr(DocuOpenFile), identifierstr(Grid), "@SYS4167"));
        }
        else
        {
            if (! binData)
            {
                binData = new BinData();
                if (binData.loadFile(filename)) //only works if file not locked
                {
                    docuValue.File = binData.getData();
                }
                else
                    throw error(strfmt("@SYS54217",filename));
            }
            else
                docuValue.File = binData.getData();
        }
    }

    docuValue.update();

    ttscommit;
    return docuValue;
}

где docuValue.File имеет вид container.
