Flexviewer 2.0 Thematic app help

LeeAllen

I am trying to implement the Flexviewer 2.0 Thematic mapping viewer. Once activated, there is no way that I can find to turn off the thematic layers. Any idea on how to do this?

Yes for the compiled version, there is no way to turn off thematic layers once activated.
however, if you are working with source, try replacing widgetClosedHandler and widgetOpenedHandler with the code below
           

private function widgetClosedHandler(event:Event):void
            {
                clearSelectionAndHideInfoWindow();
                featureLayer.visible = false;
                sendLegendURL("");
                map.removeEventListener(MapMouseEvent.MAP_CLICK, onMapClick);
                map.removeEventListener(ExtentEvent.EXTENT_CHANGE, onExtentChange);
                var operationalLayerData:Object = ht.find(currentTheme.labelref);
                operationalLayerData = ht.find(currentTheme.labelref);
                if (operationalLayerData)
                {
                    operationalLayerData.visible = false
                    currentTheme.visible = false;
                    previousOperationalLayer = currentOperationalLayer = operationalLayerData.label;
                    /*currentQueryParameter = getCurrentQueryParameter(currentOperationalLayer);
                    if (currentQueryParameter)
                    {
                        sendLegendURL(currentQueryParameter.legendurl);
                    }
                    else
                    {
                        sendLegendURL("");
                    } */  
                }
                ViewerContainer.dispatchEvent(new AppEvent(AppEvent.MAP_LAYER_VISIBLE, operationalLayerData));
                    
                
            }

            private function widgetOpenedHandler(event:Event):void
            {
                if (featureLayer)
                {
                    featureLayer.visible = true;
                }
                
                
                var currentOperationLayerData:Object = ht.find(currentOperationalLayer);
                if (currentOperationLayerData)
                {
                    currentTheme.visible = true;
                    currentOperationLayerData.visible = true;
                    ViewerContainer.dispatchEvent(new AppEvent(AppEvent.MAP_LAYER_VISIBLE, currentOperationLayerData));
                }
                
                
                var currentQueryParameter:Object = getCurrentQueryParameter(currentOperationalLayer);
                if (currentQueryParameter)
                {
                    sendLegendURL(currentQueryParameter.legendurl);
                }
                else
                {
                    sendLegendURL("");
                }
                map.addEventListener(MapMouseEvent.MAP_CLICK, onMapClick);
                map.addEventListener(ExtentEvent.EXTENT_CHANGE, onExtentChange);
            }
