    Error: Unknown result

    Reply Quote
    When trying to upload a file, we sometimes get the following error:
     
    Unknown result: 
    <script type='text/javascript'>if(window.parent.CurrentUpload)window.parent.CurrentUpload.UploadError('PageID_30_ControlID_7_fudForumProfile_wsUserDetails_txtForumAvatar_UploadPersistedFile1Image_1319788925232_1','Object reference not set to an instance of an object.','')</script>
     
    What might cause this, and how can I prevent it?
      
    Regards, Marja

    The upload seems to happen... the progress bar fills up, but then the error occurs. And it seems to happen just before the OnFileUploaded event is triggered, because that doesn't fire once the error has occurred.
     
    My code:
     
    <CuteWebUI:UploadPersistedFile ID="UploadPersistedFile1" DirtyText="<%$ Resources:wsGeneral, langUploadFileNotSaved %>" InsertText="<%$ Resources:wsGeneral, langSelectFile %>" OnFileUploaded="AjaxUploader_FileUploaded" AutoUseSystemTempFolder="false" TempDirectory="~/sysfiles/TempAjaxUploader/" ItemTextTemplate="<br/>{0} {1} ({2})" runat="server">
    </CuteWebUI:UploadPersistedFile>
     
    The DLL I'm using is CuteWebUI.AjaxUploader.dll version 3.0.0.0 with file description "AjaxUploader 3.0.20110321".

    Hi MarjaR,
     
    Can you create a page by the code below? Does it get the same problem?
     
    <%@ Page Language="C#" Title="Customize the queue UI" %>

    <%@ Register TagPrefix="CuteWebUI" Namespace="CuteWebUI" Assembly="CuteWebUI.AjaxUploader" %>
    <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Frameset//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-frameset.dtd">
    <html xmlns="http://www.w3.org/1999/xhtml">
    <head id="Head1" runat="server">
    </head>
    <body>
        <form id="Form1" runat="server">
            <CuteWebUI:Uploader ID="uploader1" runat="server">
            </CuteWebUI:Uploader>
        </form>
    </body>
    </html>
     
    If so, please post the uploader page url above, so we can check it for you.
     
    Regards,
     
    Ken

    Hi Ken,
     
    Thank you for your reply.
    No, a test page like that does not get the same problem.
     
    Some more background information about my situation:
     
    The CuteWebUI:UploadPersistedFile is part of a custom user control for uploading and resizing images, which is added to the page dynamically in the CreateFieldSet method of a subclass of DetailsView.
     
    Used as just another control on a plain page, it works correctly. You can see it in action here: http://v3manual.clubwebware03.nl/uploadtest.aspx 
     
    But when used in the DetailsView context, so dynamically added in CreateFieldSet , it's getting the error I started this forum thread about. 
     
    But... I do not always get that error. Sometimes it works just fine. I can't put my finger on it... that's why I'm asking for help.
     
    Regards, Marja

    Hi MarjaR ,
     
    Can you create an example page or an user control which can reproduce this issue and send it to Kenneth@CuteSoft.net? So we can check it for you.
