Error In ScriptResource.axd: "Object Of Type 'Sys.Extended.UI.AccordionBehavior' Cannot Be Converted To Type 'Sys.UI.Behavior'
Oct 14, 2010I have an asp.net web site where I'm trying to resolve what looks like a problem with ASP.NET AJAX:
Microsoft JScript runtime error:
Sys.ArgumentTypeException: Object of
type
'Sys.Extended.UI.AccordionBehavior'
cannot be converted to type
'Sys.UI.Behavior'. Parameter name:
instance
I've googled around a lot, and looked at the code presented (see below, no idea what it means) but no luck.
I've tried changing scriptmanger scriptmode to release, and a bunch of other things too.
Details:
Visual Studio 2010
ASP.NET 4.0
Ajax control toolkit 4.0
jQuery 1.4.2
jQuery UI 1.8.5
JS Code the error occurs in, inside ScriptResource.axd:
dispose:function()
{
var c=this;
b.UI.Behavior.callBaseMethod(c,eb); --------- this line
var d=c._element;
if(d)
{
var f=c.get_name();
if(f)
d[f]=a;
var e=d._behaviors;
Array.remove(e,c);
if(!e.length)
d._behaviors=a;
delete c._element
}
}
Declaration of accordion control:
<%@ Register Assembly="AjaxControlToolkit" Namespace="AjaxControlToolkit" TagPrefix="atlas" %>
(snip)
<atlas:Accordion ID="menu" runat="server" SelectedIndex="0"
ContentCssClass="accordionContent" FadeTransitions="true" FramesPerSecond="30"
TransitionDuration="250" AutoSize="None" Width="270">
</atlas:Accordion>
*Update: *
Added accordion control declaration as requested, is there anything else I can add that could be useful?
Does anyone have any idea about this error at all - am I right in thinking it's MS AJAX not playing nicely with other javascript (probably jQuery UI) on the page?

Sep 7, 2010I have a main page with several menu choices, one of which launches an ajax enabled window. The following pattern occurs:If I:
1) Launch site

4) close pages
All is OK.If I repeat the steps, but in step 2 I select an ajax enabled page and them launch popup, I get the following error:Message: Sys.ArgumentTypeException: Object of type 'Sys.UI._Timer' cannot be converted to type 'Sys.UI._Timer'.I have spent days on this and have been unable to solve it. If I remove the ajax ToolkitScriptManager and update panels from any of the pages and launch the popup, it works. Can anyone offer some guidance?that are not ajax enabled and then selethat includes an ajax enabled popup window. T
