I'm getting this annoying error (Windows 2003, IE6 w/ caching turned off) when running a page that includes the AJAX Toolkit

 

It eventually goes away if i refresh the page enough times, but that is not the solution to tell the users of the site when this goes live....

any ideas on what is going on and more importantly how to fix it?

Happening some more on another page....

 this is some of the aspx markup

            <atlas:UpdatePanel ID="Panel1" runat="server">
                <ContentTemplate>
                    <asp:TextBox ID="txtEmailTo" CssClass="unwatermarked" runat="server" Width="300px" ValidationGroup="EmailTest" />
                    <asp:RequiredFieldValidator ID="reqEmailTo" ControlToValidate="txtEmailTo" ValidationGroup="EmailTest" Display="Dynamic" runat="Server"><img alt="Required!" src="/images/icons/alert_sm.gif" class="SpacedImage" /></asp:RequiredFieldValidator>
                    <asp:RegularExpressionValidator ID="rgxEmailTo" ValidationExpression="^([0-9a-zA-Z]([-.\w]*[0-9a-zA-Z])*@([0-9a-zA-Z][-\w]*[0-9a-zA-Z]\.)+[a-zA-Z]{2,9})$" ControlToValidate="txtEmailTo" ValidationGroup="EmailTest" Display="Dynamic" runat="Server"><img alt="Invalid Email!" src="/images/icons/alert_sm.gif" class="SpacedImage" /></asp:RegularExpressionValidator>
                    <asp:ImageButton ID="btn1" BorderStyle="None" runat="Server" ValidationGroup="EmailTest" ImageAlign="AbsMiddle" ImageUrl="~/images/buttons/send.gif" OnClick="SendThisEmail" />
                </ContentTemplate>
            </atlas:UpdatePanel>

<atlasToolkit:TextBoxWatermarkExtender ID="TextBoxWatermarkExtender1" runat="server">
    <atlasToolkit:TextBoxWatermarkProperties 
        TargetControlID="txtEmailTo" 
        WatermarkText="Enter Email Address" 
        WatermarkCssClass="watermarked" />
</atlasToolkit:TextBoxWatermarkExtender>

 

I visit that page, i get this error:





I hit "cancel" and refresh the page and get that popup a few times......  then after 2 or 3 times of that i get hit with this error:





Click "No", refresh the page... same error, so rinse and repeat, *finally* opening up the page properly






So other than getting rid of the alert box and hitting F5, nothing is different between each page load.......

It sounds like you've got a race condition where something is trying to use Atlas before Atlas has finished initializing. I'll guess that you've got something attached to the page's onload event. But Atlas isn't initialized until it fires the Sys.Application.load event.

I'll guess that you've got something attached to the page's onload event.

I have nothing extra wired in Javascript-wise on this page.. 

David Anson:

But Atlas isn't initialized until it fires the Sys.Application.load event.

But, with the error above, even if Atlas went to fire off the Sys.Application.load event, it still wouldn't be able to find the "Sys" object to do so

(Atlas creates the Sys.* namespace, so it will have access to it.) Could you please create a simple, self-contained sample to demonstrate this problem? It'd be very helpful if we could see it for ourselves. Failing that, you might spend some time with Firebug to see if anything stands out there that seems suggestive.

It sounds like you're missing some items in your web.config file. Set up a new dummy ajax site in VS and compare what's in that web.config with what you see in yours. 

 Hi friends,

Im also facing this problem, please help me to sort out this issue 

I also Faced the same problem. This solution may also help some developers. If ur using Script Manager and other control. Put ur java Script code at the lowest part. The error will be removed. but if it will be above the <ScriptManager> tag. Error will sure come.  RAJIV ROHILLA

You can also add/register/assign the js file with the scriptmanager itself on your page. I would recommend doing that. But yes, make sure ScriptManager is above all controls so that it is initiated before any control has to use it. Same goes with the Sys - if Sys is defined in the head - you will recieve that error because the Script Manager is defined in the body. You basically have three choices, place the javascript code at the end, reference the js file through the scriptmanager, or else place the javascript code right after the scriptmanager.

 Hope it helps!

Web.Config mistake something configuration.You can create new website with AJAXEnabledWebSite1 Template and copy some value in Web.config to your project

 Hope to help

 Can you expand on the Add-Register issue... I am pretty unfamiliar with AJAX and was just following this simple tute : http://www.asp.net/AJAX/Documentation/Live/tutorials/IntroductionUpdateProgress.aspx

about inserting an UpdateProgress control -- it had me drop a scriptManager, then a UpdatePanel, then an UpdateProgress tool on the page...thats it.

 Plus some teeny code behind for the button --- I checked my markup to see if I have JAVASCRIPT but do not see ANY javascript and have NO idea how to stop the SYS error.

 
HERE IS MY MARKUP:

<%@ Page Language="vb" AutoEventWireup="false" CodeBehind="Default.aspx.vb" Inherits="ProgressTimerExample._Default" %>

<%@ Register Assembly="System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"
    Namespace="System.Web.UI" TagPrefix="asp" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<html xmlns="http://www.w3.org/1999/xhtml" >
<head runat="server">
    <title>Untitled Page</title>
</head>
<body>
    <form id="form1" runat="server">
    <div>
        <asp:ScriptManager ID="ScriptManager1" runat="server">
        </asp:ScriptManager>
        <asp:UpdatePanel ID="UpdatePanel1" runat="server">
            <ContentTemplate>
                <asp:Label ID="Label1" runat="server" Text="Initial Page Rendered"></asp:Label>
                <br />
                <asp:Button ID="Button1" runat="server" OnClick="Button1_Click" Text="Button" />
            </ContentTemplate>
        </asp:UpdatePanel>
        <asp:UpdateProgress ID="UpdateProgress1" runat="server">
            <ProgressTemplate>
                Processing...
            </ProgressTemplate>
        </asp:UpdateProgress>
   
    </div>
    </form>
</body>
</html>

 
So I dont see anyway to move javascript around... so I would like to try to register the JS file with the scriptmanager....could you explain a little more about it?
 

Hi,

it's a web.config misconfiguration :

Try adding this :

<httpHandlers>
            <remove verb="*" path="*.asmx"/>
            <add verb="*" path="*.asmx" validate="false" type="System.Web.Script.Services.ScriptHandlerFactory, System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"/>
            <add verb="*" path="*_AppService.axd" validate="false" type="System.Web.Script.Services.ScriptHandlerFactory, System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"/>
            <add verb="GET,HEAD" path="ScriptResource.axd" type="System.Web.Handlers.ScriptResourceHandler, System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" validate="false"/>
</httpHandlers>
<httpModules>
         <add name="ScriptModule" type="System.Web.Handlers.ScriptModule, System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"/>
</httpModules>

thanks a lot, copying the web.config file from the sample website of the ajax control toolkit solved my problem...

To ricingr :

I've got the same problem. Thanks, it works now by your advice.

Still give respect to others.
