I reload the items within a RadComboBox using the client-side API. I'm not using the WS load on demand feature, but solely the JS api to add items to the combo. When the items are refreshed and a postback happens, I'm getting this error below. When it goes to load the combo client-state, an error occurs. We are using the last 2009 Q3 version.
Thanks.
