In the AJAX Control Toolkit 15.1 sample site when I go to the tabs page then on postback I get this error:
Unhandled exception at line 1, column 56851 in http://localhost:50192/SampleSite/bundles/MsAjaxJs?v=c42ygB2U07n37m_Sfa8ZbLGVu4Rr2gsBo7MvUEnJeZ81
0x800a138f - JavaScript runtime error: Unable to get property 'length' of undefined or null reference
I also get this same error on our website that has a tab container.
On a positive note the IE 8 bug with tab container is fixed. So now just this issue and were good :)
Comments: I am getting the same error. It appears to be happening in microsoftajax.js <asp:ScriptManager ID="sm" runat="server" EnablePartialRendering="true" AsyncPostBackTimeout="3600" ScriptMode="Release" > Sys.UI.DomEvent._removeHandler=function(a,e,f){var d=null,c=a._events[e];for(var b=0,______g=c.length______;b<g;b++)if(c[b].handler===f){d=c[b].browserHandler;break}if(a.removeEventListener)a.removeEventListener(e,d,false);else if(a.detachEvent)a.detachEvent("on"+e,d);c.splice(b,1)}; error occurs at the bolded code above. a=the tab container object e='mousedown' at c=a._events[e];, c gets the value undefined, thus causing the length method to fail. callstack is below... > Sys.UI.DomEvent._removeHandler JavaScript Sys.UI.DomEvent.removeHandler JavaScript Sys.Extended.UI._CommonToolkitScripts.prototype.removeHandlers JavaScript Sys.Extended.UI.TabPanel.prototype.dispose JavaScript Sys._Application.prototype.dispose JavaScript Sys._Application.prototype._unloadHandler JavaScript Anonymous function JavaScript hope this helps.
