Hi,

I have updated my existing application with rad controls- radcombobox, radlistbox etc, everything was working just fine but as soon as we launched our application in production the radcontrols stopped working. We disabled our state server and everything started working again but without state server our customers are facing log out /time out issues
The javascript error on the page is as below.

After looking into the details, looks like some control is affecting the state. Could someone please suggest something if they had faced similar kind of  issue.

Thanks,
Ruby
