 When using Select Within, layers that are not turned on or hidden are
 available to the user.  There should be a filter to only select those
 layers that are turned on and selectable - and their parent Group is
 turned on.

 Something like the following:

 function FillLayerList()
 {
  //GL: FILTER BASED ON LEGEND
  var currentVisibleLayer=0;
  var list = document.getElementById("layers");
  var listNames = document.getElementById("layerNames");
  list.options.length = 0;
  var map = GetParent().Fusion.getMapByName(mapName);
  var layers = map.aMaps[0].getSelectableLayers();
  if(layers.length > 0) {
  for(var i = 0; i < layers.length; i++) {
  var layer = layers[i];
  if(layer.visible)
  {
  var groupVisible = true;
  var currentGroup = layer.parentGroup;
  while(currentGroup.name != "layerRoot")
  {
  if(!currentGroup.visible)
  groupVisible=false;
  currentGroup = currentGroup.parentGroup;

  }
  if(groupVisible!=false)
  {
  list.options[currentVisibleLayer] = new Option(layer.legendLabel != ""?
 layer.legendLabel: layer.layerName);
  if (i == 0) list.options[0].selected = true;
  listNames.options[currentVisibleLayer] = new Option(layer.layerName);
  currentVisibleLayer++;
  }
  }
  }
  } else {

  list.options[0] = new Option("__#BUFFERNOLAYER#__");
  }
  document.getElementById("Done").disabled = layers.length == 0;
 }
