Operation Layer drawing underneath BaseMap Layers

Question

I am stumped, everything was working fine and then I added another basemap layer to config.xml and now when I switch between basemaps my operational layers are drawing underneath my basemap. For example I have a cached base map with building footprints and in my operational layer which is dynamic I have a point featureclass that I am labeling and the labels draw or render underneath the buildings. I thought operational layers always draw on top of the basemaps but clearly they are not in my case. Any thoughts? I have provided my config.xml file in case someone sees something I am not. Thanks in advanced for anyone who can help with this.

Yes, it is a bug and will be fixed in the next version.

In the meantime, if you are using the uncompiled version of the viewer, update the following methods in MapManager.mxml as follows:

private function loadNextBasemapLayer():void
{   
     var basemapLayerObject:Object = m_basemapLayers[m_basemapLayerIndex];
     // configure popups, if any
     configureLayerRenderer(basemapLayerObject, false);
}

private function loadNextOpertionalLayer():void
{
     var optLayerObject:Object = m_operationalLayers[m_operationalLayerIndex];
     // configure pop-ups, if any
     configureLayerRenderer(optLayerObject, true);
}

private function loadNextOperationalOrBasemapLayer(isOperationalLayer:Boolean):void
{   
     if (isOperationalLayer)
     {   
           // add layer to map after popups have been configured, if any
           var optLayerObject:Object = m_operationalLayers[m_operationalLayerIndex];
           addLayerToMap(optLayerObject);
                    
           m_optLayerTable.push(optLayerObject);
           m_operationalLayerIndex++;
           if (m_operationalLayerIndex < m_operationalLayers.length)
           {
                 loadNextOpertionalLayer();
           }
      }
      else
      {   
            // add layer to map after popups have been configured, if any
            var basemapLayerObject:Object = m_basemapLayers[m_basemapLayerIndex];
            addLayerToMap(basemapLayerObject);
                    
            m_basemapLayerIndex++;
            if (m_basemapLayerIndex < m_basemapLayers.length)
            {
                  loadNextBasemapLayer();
            }
      }
}

I was able to reproduce the same issue with both 2.5 and 3.0.  I used 2 basemaps with sublayers (one imagery, one streets) and one operational layer.  I have logged a bug for this under:
#NIM082418  Operational layers disappear if basemap layers have sublayers.

Thanks,
Chris

I am experience similar problems. Three of my operational layers are drawing underneath aerial basemaps (both in house aerial imagery and the Bing Hybrid map.

Oddly, if I moved the two cached operational layers to the top of the operationallayers tag, it corrected part of the problem. 
I also added a dummy layer as the first operational layer set to visible="false" and set to not show in the Layer List or TOC Widget(which I use). This seemed to correct the problem.

Are you using the TOC widget or the out of the box Layer List widget?
