it seems the $telerik.$find() function is not working. I've set all scriptreferences that are provided in the demo on my master page but once the function 'addCategoriesToArray' function fires the radPanelBar is not found. i've put the scripts inside a RadScriptBlock so the ClientID's are being resolved nicely.
The first error i'm getting is: Cannot get the value of the property get_element: the object is null or not defined. This happens inside the following function:
$ = $telerik.$;
categoryPanelBar = $find(
The panelbar is right there on the usercontrol and the id is the same as the resolved id the js is trying to find with $find.
If i alert the categoryPanelbar var it's always null.
Has anyone else encountered this issue and found a solution?
