You don't need to use anything from Weblocks to do this (apart from rendering the initialization code in a custom widget, which is simple). No CLOS, no views. The dynamic updates can be served simply by vanilla Hunchentoot handlers (or Weblocks dispatchers if you want) as JSON or whatever data format is required. I suggest you try it in a plain Hunchentoot application and then transfer it to your Weblocks app. Leslie -- You received this message because you are subscribed to the Google Groups "weblocks" group.
