Query Widget from New Sample Viewer

azgis

I need to modify this widget to return only two 'baseMaps' (it is written to return all baseMaps). I have been successfull except for one problem: the list in the combo box populates with duplicate values, 5 in fact, or 10 if I choose to include 2 layers, as in my example below. I use an index value to select the layer (the default is var i from the loop).
The original script is as follows:

private function getBasemapLayer():ArrayCollection
   {
    var baseMaps:ArrayCollection = new ArrayCollection();
    for(var i:Number=0; i<configData.configBasemaps.length; i++)
          {
           baseMaps.addItem(configData.configBasemaps.label);
          }
    return baseMaps;
   }
  // TODO: Change to pull from configdata object
      private function getLayers():ArrayCollection
   {  
    var basemapLyrs:ArrayCollection = getBasemapLayer();
    var layers:ArrayCollection = new ArrayCollection();
    for(var i:Number = map.layerIds.length -1; i >= 0; i--)
    {  
     var basemapLyr:Boolean = false;
     for each(var id:String in basemapLyrs){
      if (map.layerIds == id){
       basemapLyr = true;
       break;
      }
     }
     if (basemapLyr) continue;
     var layer:Layer = map.getLayer(map.layerIds);
     if(!(layer is GraphicsLayer))
      layers.addItem(layer);
    }
    return layers;
     }

My modification is to the last section:

                                        if (basemapLyr) continue;
     var layer:Layer = map.getLayer(map.layerIds[2]);
     var layer2:Layer = map.getLayer(map.layerIds[3]);
     if(!(layer is GraphicsLayer))
      layers.addItem(layer);
      layers.addItem(layer2);
    }
    return layers;
     }

Attached is a jpg of the combo box: it is populated with the two layers, but in pairs of 5, i.e. five duplicate items each (the second layer is in white, hard to see) .

The dataprovider for the combo box is mMapServices, which is declared = to the getLayers() function in the init().

Thanks,

What about if i want to ask for unique values of a field? cause it will make a query @ all my layers but will return me only 500(or configured number of) features, how i can set the query to select only "DISTINCT" values?

Thanks in advance,
Cristiano Benato.
