Query to search numbers

HectorChapa

What am I doing wrong.

It doesnt want to zoom to this location using this query.
Any ideas why. I think because the field I am searching is a double.
Could someone guide me of doing a simple query that searches for that number.

Hector,

A point does not have an extent to you can not use the code you are using to zoom to the point.

Here is some code that handles that.

private function executeCompleteHandler(event:FindEvent):void             {                 myGraphicsLayer.clear();                                  //resultSummary.text = "Found " + event.findResults.length + " results.";                 myGraphicsLayer.symbol = smsFind;                                  var resultCount:int = event.findResults.length;                                  if (resultCount == 0)                 {                     Alert.show("No State ID found. Please change your search.");                 }                 else                 {                     // add feature as graphic to graphics layer                     for (var i:int = 0; i < resultCount; i++)                     {                         var graphic:Graphic = FindResult(event.findResults).feature;                         graphic.toolTip = event.findResults.foundFieldName + ": " + event.findResults.value;                         myGraphicsLayer.add(graphic);                     }                                          // zoom to extent of all features                     var graphicProvider:ArrayCollection = myGraphicsLayer.graphicProvider as ArrayCollection;                     if (graphicProvider.length == 1                         && graphicProvider[0].geometry.type == Geometry.MAPPOINT){                         var mp:MapPoint = graphicProvider[0].geometry as MapPoint;                         mainMap.zoom(1 / 16, mp);                         mainMap.centerAt(mp);                     }else{                         var graphicsExtent:Extent = GraphicUtil.getGraphicsExtent(graphicProvider.toArray());                         if(graphicsExtent){                             mainMap.zoomTo(graphicsExtent.expand(1.4));                         }else{                             var mp2:MapPoint = graphicProvider[0].geometry as MapPoint;                             mainMap.zoom(1 / 16, mp2);                             mainMap.centerAt(mp2);                         }                     }                 }

Ok got the query to work but is still not zooming in to that location.
Here is the code. could you tell me what I am doing wrong.

private function doFind():void
    {
     findTask.execute(myFindParams);
    }
    
    private function executeCompleteHandler(event:FindEvent):void
    {
     myGraphicsLayer.clear();
     
     resultSummary.text = "Found " + event.findResults.length + " results.";
     myGraphicsLayer.symbol = smsFind;
     
     var resultCount:int = event.findResults.length;
     
     if (resultCount == 0)
     {
      Alert.show("No State ID found. Please change your search.");
     }
     else
     {
      // add feature as graphic to graphics layer
      for (var i:int = 0; i < resultCount; i++)
      {
       var graphic:Graphic = FindResult(event.findResults).feature;
       graphic.toolTip = event.findResults.foundFieldName + ": " + event.findResults.value;
       myGraphicsLayer.add(graphic);
      }
      
      // zoom to extent of all features
      var graphicProvider:ArrayCollection = myGraphicsLayer.graphicProvider as ArrayCollection;
      var graphicsExtent:Extent = GraphicUtil.getGraphicsExtent(graphicProvider.toArray());
      mainMap.extent = graphicsExtent.expand(1.4); // zoom out a little
     }
    }

Here is the mxml.

Hector,

You are setting it here:

<esri:GraphicsLayer id="myGraphicsLayer"        graphicProvider="{queryTask.executeLastResult.features}"        symbol="{sfs}"/>

So you will need to change it to a SimpleMarkerSymbol or just remove it all together.

HectorChapa

Thanks where do I change that. I feel stupid why didnt i thought of that.

RobertScheitlin__GISP

Hector,

Your issue is that you data is point geometry and the symbol that you are giving to the myGraphicsLayer is for a polygon.
