Clustering Sample doesn't display InfoWindow for non-clustered points

Hi,

Does anyone know how I could modify the Clustering Sample so that when you zoom into individual points and click on them they display an InfoWindow.

Currently in the example above, an InfoWindow only appears when you click on one of the green points that are part of a cluster. When you click on an individual red point you don't get the InfoWindow.

Thanks,
Karl

Not tested, but you should just be able to add a click event to the feature layer or another event listener on the map. Try it out.

map.addEventListener(MouseEvent.CLICK,mouseClickHandler);

private function mouseClickHandler(event:MouseEvent):void
   { 
    showInfoWindow(Graphic(event.target),event.stageX, event.stageY);    
        
   }

 <esri:FeatureLayer id="featureLayer"
         clusterer="{clusterer}"
         definitionExpression="POP1990 &gt; 75000"
         mode="snapshot"
         outFields="*"
         symbol="{defaultsym}" click="mouseClickHandler(event)"
...

This sample shows a better way to handle the events. It uses a Graphic event and should help you avoid any type coercion errors.

protected function fLayer_graphicAddHandler(event:GraphicEvent):void
   {
    event.graphic.addEventListener(MouseEvent.CLICK,mouseClickHandler);
   }

<esri:FeatureLayer id="featureLayer"
         clusterer="{clusterer}" graphicAdd="fLayer_graphicAddHandler(event)"
         definitionExpression="POP1990 &gt; 75000"
         mode="snapshot"
         outFields="*"
         symbol="{defaultsym}"

the mouseClickHandler would be the same as above.

That's great Alex, thanks.

Both methods work for me.
