SFV 1.3 layerDefinitions problem

Question

Hi all, I used in my website a layer definition to filter a layer.
It works great...
Inside this layer I have shape overlapped and my problem is that when I use Select by point (searchWidget tool) I select ALL the overlapped shape...but I wish I could select just what I see...
Can I store somehow the layerDefinitions query or can I get layerDefinitions values to add to queryTask?

Thanks

David

Davide,

OK, helps to be specific. Add this//Loop though the map layers to find one that matches the searchwidgets selected layer
     for each(var layer:* in map.layers)
     {
      //Check to see if this particular map service layer has the same url as
      //the one selected by the searchWidget, minus the layer designator
      //If the urls match then use the layer designator to get the appropriate
      //layerDefinition and add it to the querys where clause
      if(layer is ArcGISDynamicMapServiceLayer || layer is ArcGISTiledMapServiceLayer)
       if(layer.url == queryLayer.substring(0,queryLayer.lastIndexOf("/"))){
        if(layer.layerDefinitions)
        {
         query.where = layer.layerDefinitions[parseInt(queryLayer.substring(queryLayer.lastIndexOf("/")+ 1))];
         trace(query.where);
        }
       }
     }

Thanks u Robert!!
Wonderful...it perfectly works...

Davide, Yes you can use existing layerDefinitions and just append them to your query as I demonstrate in this sample. * AGE_50_64 + AGE_65_UP ]]> AGE_50_64 + AGE_65_UP ]]> AGE_50_64 + AGE_65_UP ]]> Thanks so much Robert...but where can I put this if I use Graphic Search in the following code?private function queryFeaturesGraphical(geom:Geometry):void { var i:Number = cboLayerGraphical.selectedIndex; var querySpatialRel:String = "esriSpatialRelIntersects"; queryLayer = configSearchGraphical.url; queryGeom = geom; queryFields = configSearchGraphical.fields; queryTitleField = configSearchGraphical.titlefield; queryLinkField = configSearchGraphical.linkfield; if (queryLayer) { var queryTask:QueryTask = new QueryTask(queryLayer); var query:Query = new Query(); query.geometry = queryGeom; query.outFields = queryFields.split(","); query.returnGeometry = true; query.spatialRelationship = querySpatialRel; query.outSpatialReference = map.spatialReference; queryTask.execute(query, new AsyncResponder(onResult, onFault)); showMessage(loadingLabel, true); showStateResults(null); // on result function onResult(featureSet:FeatureSet, token:Object = null):void { try { var recAC:ArrayCollection = createRecordData(featureSet,""); addSharedData(widgetTitle, recAC); wRepeater.dataProvider = recAC; showMessage(selectionLabel + " " + featureSet.features.length, false); //Davide } catch (error:Error) { showMessage(error.message, false); } } //on fault function onFault(info:Object, token:Object = null) : void { showMessage(info.toString(), false); } } }
