I downloaded DWR 2.0.2 source, I still can't see any GI utility code. I would assume GI releated stuff has not been released yet officially. Can you tell me any time line for this support? -- Deha Peker

I hope that 2.1 (in which this code should feature) will be out early next year. However, I'm not sure that this code will change between now and then, so you could just copy the javascript into your project. Joe. On Nov 23, 2007 12:34 AM, dio <deha.peker@...> wrote:
