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: Appending this to the post above. We also get this exception: 0x800a139e - JavaScript runtime error: Sys.InvalidOperationException: Type Sys.Extended.UI.TabStripPlacement has already been registered. The type may be defined multiple times or the script file that defines it may have already been loaded.
