RadEditor in Sharepoint 2010 SP1 doesn't works

Hi, after to apply the SP1 and August 2011 CU, the RadEditor seems not working when is in a RadAjaxPanel. According with the stack trace (js) the problem is in the next script:

Telerik.Web.UI.Editor.Modules.RadEditorHtmlInspector.callBaseMethod(this,"dispose");
  c is null

MicrosoftAjax.js

SCRIPT5007: Unable to get value of the property 'apply': object is null or undefined
ScriptResource.axd?d=lI4GBBPOhB4Zcf6kyDFujm4Ja0NSR2z_uNkLxbjbyFwoxyFTYUCSCx2vZaWRtY0xMD1OKViMXMR42wVjTttBvWOvsHpuusu5R_yQdb4Gyj9k4vhFumRFnkBY4p1IePVivOWjmto05Fs18MNy7nwsH2Tlmsk1&t=5c2f384e, line 5 character 19552

I'm working with the last version of telerik (2011.2.915.35)

Somebody else have the same error or have some information about that?

Thanks alot

Hello Juan Carlos Juarez,

I installed the SP1 on our test server, but I was not able to reproduce the issue. In order to help you further I will need some additional information:

1. Send the web.config file of your SP2010 site.
2. Send me the part of the master page where you use RadScriptManager (or the whole aspx source).
3. Send me the code where you are using RadEditor and RadAjaxPanel.
4. Send me the html code of the page where the problem occurs.

Kind regards,
Stanimir
