Legend in reverse order since 2.4 upgrade

TammyBearly — Mon, 10 Oct 2011 19:40:24 GMT

I recently upgraded to the 2.4 API. Now my legend displays the polygons first, then the points. Before I upgraded it was the other way around. Why is this happening?

Here is the code I am using:

<?xml version="1.0" encoding="utf-8"?>
<s:Application xmlns:fx="http://ns.adobe.com/mxml/2009"
      xmlns:s="library://ns.adobe.com/flex/spark"

      xmlns:mx="library://ns.adobe.com/flex/mx" minWidth="955" minHeight="600"
      >
<fx:Script>
<![CDATA[

   import mx.collections.ArrayCollection;
   private function loadLayer_Handler():void{
    legendLayer.visibleLayers = new ArrayCollection([13,14,77,78,88,89]);
   }
]]>
</fx:Script>
<s:layout>
<s:HorizontalLayout gap="0"/>
</s:layout>
<esri:Legend id="myLegend" width="100%"
     respectCurrentMapScale="true"
     layers="{[ legendLayer ]}"
     map="{myMap}"
     height="100%"/>

   </esri:Extent>
</esri:extent>
<esri:ArcGISTiledMapServiceLayer id="baseLayer" url="http://server.arcgisonline.com/ArcGIS/rest/services/World_Topo_Map/MapServer"/>

             url="http://ndis-flex.nrel.colostate.edu/ArcGIS/rest/services/CHA_HunterBase_Map/MapServer"/>
</esri:Map>

</s:Application>

When I compile with agslib-2.2-2010-12-08.swc it is in the correct order. See image map2.2.gif.

But when I compile with agslib-2.4-2011-7-25.swc it is reversed. See image map2.4.gif.

Is anyone else having this trouble?

Using ArcGISDynamicMapServiceLayer.layerVisibility to change point symbols

TammyBearly — Wed, 26 Oct 2011 02:07:37 GMT

I found out that if I do not set the layerVisibility it works fine. It does not display the legend in reverse order.

I tried setting the layerVisibility in mxml and actionscript and in each case it reverses the legend.

What changed in 2.4 to cause this? It does not happen in 2.2.

I am using layerVisibility to turn on/off layers as the user zooms in to display different point symbols. Is there another way to do this?

Any help is appreciated!
