Robert,

I am getting the error:
1151: A conflict exists with definition LAYER_VISIBILITY_CHANGED in namespace internal.
for the following line in the AppEvent.as: public static const LAYER_VISIBILITY_CHANGED:String = "layerVisibilityChanged";

Another question:
for        SiteContainer.dispatchEvent(new AppEvent(AppEvent.LAYER_VISIBILITY_CHANGED, false, false, layer.name)); in place of layer.name do I need to put the name of the layer in the TOC?  For example, layer.Zoning.

Thanks.

Stuart,

Add this to the AppEvent.as/**
        * event added by me to listen for a layer being turn off or on in the map
        * event for when a layers visibility has changed
        */
        public static const LAYER_VISIBILITY_CHANGED:String = "layerVisibilityChanged";

In the onLayerShow function and the onLayerHide functions of the TocMapLayerItem.as addSiteContainer.dispatchEvent(new AppEvent(AppEvent.LAYER_VISIBILITY_CHANGED, false, false, layer.name));

In the onCheckBoxClick function and the onCheckBoxDoubleClick function of the TocItemRenderer.as addSiteContainer.dispatchEvent(new AppEvent(AppEvent.LAYER_VISIBILITY_CHANGED, false, false, event));

in the MapManager or where ever you want to call the popup put this line in the init function.SiteContainer.addEventListener(AppEvent.LAYER_VISIBILITY_CHANGED, yourPopupFunction);
