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 using a tabcontainer in an updatepanel. Any action that causes the taboontainer to be disposed, either by updatepanel refresh or navigation away from the page is throwing the JavaScript runtime error: Unable to get property 'length' of undefined or null reference.
