An issue I see with legend symbology in AGS JS TOC is it does not work in IE for secured services. We a service on ArcGIS Server 10.0 coming in to the JS API 3.3 viewer with newest AGS JS TOC widget code and see this. I called ESRI, they know about it, it has a NIM. It's something about how IE can't get bitmaps as pieces of text or something obscure, I forget. But it works in all other browsers. Just wondering if anyone found a way around this IE bug? Perhaps it will work if we put the service on Server 10.1 with the legend features? Although we'll be on 10.0 for a while.
Nianwei thank you again, your code and the documentation are great. I would love to see ESRI officially include your AGS JS TOC widget into the API!!
