Hey ArcGIS users

You can create an ArcGIS Server based layer using the AWX Flex API. In the below sample, I'm loading a layer from a specified endpoint and then when I click click on the button, I'm turning off the "water" layer in the ArcGIS group layer.

      var arrCol : ArrayCollection = data as ArrayCollection;
      for each ( var layerVisibility : LayerVisibility in arrCol)

      trace( info );
