I have a usercontrol inside a panel, that I would like to display, but I keep on receiving : Microsoft JScript runtime error: Unable to get value of the property 'UI': object is null or undefined
VS2010
Latest Nu-get Ajax Toolkit
.net 4.0
Comments: The error still exists on .NET 4.5 with the latest version. So reverting back to v4.1.5116 and jQuery 1.2.6 works fine on .NET 4.5
