[Solved] javascript error in 2010.3 1318

[Sean Cross]

Now that I have upgraded to 2010.3 1318, I am getting the following error when I have a combobox on my page:

Microsoft JScript runtime error: Object doesn't support this property or method

The error occurs in telerik.list.min.js at

if((j.Text==undefined?j:j.Text).toLowerCase()==o)

I get the error when I try to move away from the page.  I thought it might be due to changes in the script files but haven't be able to find anything.

My script registrar is as follows

<%= Html.Telerik().ScriptRegistrar().jQuery(false).Globalization(true).DefaultGroup(group => group
        .Add("telerik.common.js")
        .Add("telerik.grid.js")
        .Add("telerik.grid.filtering.js")
        .Add("telerik.calendar.js")
        .Add("telerik.combobox.js")
        .Add("telerik.list.js")
        .Add("telerik.autocomplete.js")
        .Add("telerik.datepicker.js"))
 %>

Any ideas?

Hello Sean Cross,

 Unfortunately we are not sure what is causing this problem. Could you please attach a sample app which shows the JavaScript error? Also in which browser is this error observed?

I have found and resolved the problem.  I had a null value for a SelectListItem Text property.  In the older release this worked fine, but in the service pack it threw the error.  Easily fixed in my case by doing a null check when building the list.

Hello Sean,

After further investigation, we was able to improve current behavior of the combobox component. Improvement will be availavable with the next official release of Telerik Components for ASP.NET MVC.
For you convenience I have attached the modified JavaScript files to this message,
