Script error while navigating using RadTabStrip.

[Sri]

I am getting following script error when I tried to navigate to a tab in RadTabStrip.

Microsoft JScript runtime error: Unable to get value of the property 'apply': object is null or undefined

at line 6 of Telerik.WebUI.WebResource_6.axd?_TSM_HiddenField=RSM_TSM&compress=1&_TSM_CombinedScrpts_=;;System.WebExtension,+Version=4.0.0.0,+Culture=neutral,+PublicKeyToken=31bf3856ad364e35;en-US;fabb1efa-938f-494c-a9c4-f313dccf73fa;ea597d4b;b25378d2;Telerik.Web.UI 

Here are more details I found debugging w/ Firebug Lite in Firefox. 

I find the error “e is undefined” at

Function.__typeName="Function";Function.__class=true;Function.createCallback=function(b,a){return function(){var e=arguments.length;if(e>0){var d=[];for(var c=0;c<e;c++)d[c]=arguments[c];d

where:

a = “prItem”

b = Object { prItem=“ct100_MainContent_ReqItems_Item_Item” }

c= Object {_msdisposeindex=27, _element=span#MainContent_ReqItems_Item, appContext=”SWNCCAF2KWGFSLJEF4GEFVC…PTYZ882DNRND46VNV375W9V”, …

d = Object { _msdisposeindex=26, _element=div#ct100_MainContent_ReqItems_Item_Item.RadComboBox, _clientStateFieldID=“ct100_MainContent_ReqItems_Item_Item_ClientState” …

e = undefined

b = Object { prItem="ctl00_MainContent_ReqItems_Item_Item"}

Any one have any idea of how to resolve it?
