Robert, did you ever got that proxy support code that Jeremy Moore mentioned in an earlier post? What I can tell it isn't implemented yet, right? Jeremy could you share some code? I would like just that part of the code because I'm using my own customized version of this TOCwidget. EDIT: I think I found a solution my self, I've only tested this a little bit in my own application that only has DynamicLayers in the legend, but it seems to work... I made just a few changes to the getLegendData function in TocMapLayerItem.as   private function getLegendData(m_layer:*):void   {    if (_legendDataLoaded)     return;    _legendDataLoaded = true;       if (m_layer.hasOwnProperty("url")){     const url:String = m_layer["url"];     if (url === null)      return;    }else{     return;    }       var httpServ:HTTPService = new HTTPService();    httpServ.requestTimeout = lTimeout;    var lname:String;    var lInfos:Array;    if (m_layer is ArcGISTiledMapServiceLayer){     if(m_layer.version >= 10.01){      if(ArcGISTiledMapServiceLayer(m_layer).proxyURL){       //If layer uses proxy (my addition for proxy support)       httpServ.url = ArcGISTiledMapServiceLayer(m_layer).proxyURL + "?" + ArcGISTiledMapServiceLayer(m_layer).url + "/legend?f=json";      }else{       //if layer doesn't use proxy (original code)       httpServ.url = ArcGISTiledMapServiceLayer(m_layer).url + "/legend?f=json";      }          httpServ.resultFormat = "text";      lname = ArcGISTiledMapServiceLayer(m_layer).id;      lInfos = ArcGISTiledMapServiceLayer(m_layer).layerInfos;      httpServ.addEventListener(ResultEvent.RESULT,function(event:ResultEvent):void{processLegend(event,lname,Number.NaN,lInfos,httpServ.url)});      httpServ.send();     }else{      lname = ArcGISTiledMapServiceLayer(m_layer).id;      ArcGISTiledMapServiceLayer(m_layer).addEventListener(DetailsEvent.GET_ALL_DETAILS_COMPLETE,function(event:DetailsEvent):void{getAllDetailsResult(event,lname)});      ArcGISTiledMapServiceLayer(m_layer).addEventListener(FaultEvent.FAULT, function(event:Event):void{FlexGlobals.topLevelApplication.dispatchEvent(new Event("legendDataLoaded$"))});      ArcGISTiledMapServiceLayer(m_layer).getAllDetails();     }    }else if (m_layer is ArcGISDynamicMapServiceLayer){     if(m_layer.version >= 10.01){      if(ArcGISDynamicMapServiceLayer(m_layer).proxyURL){       //If layer uses proxy (my addition for proxy support)       httpServ.url = ArcGISDynamicMapServiceLayer(m_layer).proxyURL + "?" + ArcGISDynamicMapServiceLayer(m_layer).url + "/legend?f=json";      }else{       //if layer doesn't use proxy (original code)       httpServ.url = ArcGISDynamicMapServiceLayer(m_layer).url + "/legend?f=json";      }      httpServ.resultFormat = "text";      lname = ArcGISDynamicMapServiceLayer(m_layer).id;      lInfos = ArcGISDynamicMapServiceLayer(m_layer).layerInfos      httpServ.addEventListener(ResultEvent.RESULT,function(event:ResultEvent):void{processLegend(event,lname,Number.NaN,lInfos,httpServ.url)});      httpServ.send();     }else{      lname = ArcGISDynamicMapServiceLayer(m_layer).id;      ArcGISDynamicMapServiceLayer(m_layer).addEventListener(DetailsEvent.GET_ALL_DETAILS_COMPLETE,function(event:DetailsEvent):void{getAllDetailsResult(event,lname)});      ArcGISDynamicMapServiceLayer(m_layer).addEventListener(FaultEvent.FAULT, function(event:Event):void{FlexGlobals.topLevelApplication.dispatchEvent(new Event("legendDataLoaded$"))});      ArcGISDynamicMapServiceLayer(m_layer).getAllDetails();     }    }else if (m_layer is KMLLayer)   {     timeOutVar = setTimeout(getKMLLegend, 100, m_layer);    }else if (m_layer is FeatureLayer){     var FeatServId:Number = Number.NaN;     var msName:String = FeatureLayer(m_layer).url.replace("FeatureServer","MapServer");     if(msName.substring(msName.length - 9) != "MapServer"){      if(FeatureLayer(m_layer).proxyURL){       //If layer uses proxy (my addition for proxy support)       httpServ.url = FeatureLayer(m_layer).proxyURL + "?" + msName.substring(0,msName.lastIndexOf("/")) + "/legend?f=json";      }else{       //if layer doesn't use proxy (original code)       httpServ.url = msName.substring(0,msName.lastIndexOf("/")) + "/legend?f=json";      }      FeatServId = parseInt(msName.substring(msName.lastIndexOf("/")+ 1));     }else{      if(FeatureLayer(m_layer).proxyURL){       //If layer uses proxy (my addition for proxy support)       httpServ.url = FeatureLayer(m_layer).proxyURL + "?" + msName + "/legend?f=json";      }else{       //if layer doesn't use proxy (original code)       httpServ.url = msName + "/legend?f=json";      }     }     if(m_layer.layerDetails.version >= 10.01){      httpServ.resultFormat = "text";      lname = FeatureLayer(m_layer).id;      httpServ.addEventListener(ResultEvent.RESULT,function(event:ResultEvent):void{processLegend(event,lname,FeatServId)});      httpServ.send();     } else {      lname = FeatureLayer(m_layer).id;      getFeatureResult(FeatureLayer(m_layer).layerDetails,lname);     }    }else{     FlexGlobals.topLevelApplication.dispatchEvent(new Event("legendDataLoaded$"));    }   } ...

Robert, I understand, thanks anyway for this great widget. I found a way to add show meta data button for WMS layers that shows a modified details window with the legend image, I'll settle for that for now. ... View more

Robert, I know you've been asked about legends for WMS layers before, and that's not your priority now. I'm thought I could take a look at this my self, as a first step I would be happy just to be able to add a single image with a hard coded imageURL for each WMS layer. Can you give me some hints how to accomplish this? My guess so far is that I might start with something like: }else if (m_layer is WMSLayer){ in the getLegendData function in TocMapLayerItem.as but then I'm lost 😃 ... View more

This was posted pretty long ago, is there anyone who has been able to do an identify on a WMS layer from flex since then? I've search the forums och documentation for ArcGIS API for flex as well as ArcGIS Viewer for Flex but haven't found anything. If WMS layers is supposed to be supported, I don't think it's too much to ask to be able to perform an identify on them... ... View more

I've been thinking and trying out some solutions for this, and ended up customizing the PopUpRendererSkin. It works but I'm not really satisfied with the solution, what I would like is to use some kind of AppEvent for showing PopUp and closing/hidning PopUp. I've been looking through the documentation but I can't find anything like that, I've tried using SHOW_INFOWINDOW and some other events without success. I've not tried to create my own custom AppEvent, because I wouldn't know how to dispatch the events when PopUp shows or hides, if I knew that I would probably not even have to create any AppEvents. Anyone knows a way to listen to the events of showing and closing/hiding a PopUp? If anyone is interested in the solution I have so far, I got the PopUpRendererSkin.mxml from downloading the API and copied it to src/com/esri/viewer/skins/ and to the default.css I added: esri|PopUpRenderer { skin-class: ClassReference("com.esri.viewer.skins.PopUpRendererSkin"); } All the code I put in PopUpRendererSkin.mxml, at the end of the commitProperties function add: // My addition for highlighting popup features...     var glExists:Boolean = false;     var glID:int;     //Go through layerIds in map to check if the highlightGraphics graphiclayer exists and if so get its id.     for (var i:int = 0; i < map.layerIds.length; i++)     {      if (map.layerIds== "highlightGraphics")      {       glID = i;       glExists = true;      }     }     //If highlightGraphics graphicslayer doesn't exist, create it and add it to the map.     if(!glExists){      var gl:GraphicsLayer = new GraphicsLayer();      gl.id = "highlightGraphics";      gl.visible = true;      map.addLayer(gl,200);      //Get the id of the graphicslayer      for (var j:int = 0; j < map.layerIds.length; j++)      {       if (map.layerIds == "highlightGraphics")       {        glID = j;        glExists = true;       }      }     }     //Set the highlight graphic symbol     var hlGraphic:Graphic = new Graphic(graphic.geometry);     switch(hlGraphic.geometry.type)     {      case Geometry.MAPPOINT:      {       hlGraphic.symbol = new SimpleMarkerSymbol("circle",22,0x000000,0,0,0,0,new SimpleLineSymbol("solid",0xFF0000,0.5,2));       break;      }      case Geometry.POLYLINE:      {       hlGraphic.symbol = new SimpleLineSymbol("solid",0xFF0000,0.3,8);       break;      }      default:      {       hlGraphic.symbol = new SimpleFillSymbol("solid",0x000000,0,new SimpleLineSymbol("solid",0xFF0000,0.4,3));       break;      }     }     //set a glow filter to the highlight graphic     var gf:spark.filters.GlowFilter = new spark.filters.GlowFilter();     gf.color = 0xFF0000;     gf.alpha = 1;     gf.strength = 2;     gf.blurX = 8;     gf.blurY = 8;     hlGraphic.filters = [gf];     //Clear the highlightGraphics graphiclayer and add the new highight graphic     map.layers[glID].clear();     map.layers[glID].add(hlGraphic);     //add eventhandlers to "unhighlight" features     map.infoWindow.closeButton.addEventListener(MouseEvent.CLICK, onInfoWindowClosed);     map.addEventListener(MapMouseEvent.MAP_CLICK, onMapClick) // --- end addition --------------- And then add a these two functions somewhere: //My handler for clicking closebutton on a popup/infowindow    private function onInfoWindowClosed(event:MouseEvent):void    {     if(hostComponent.map){      for (var i:int = 0; i < hostComponent.map.layerIds.length; i++)      {       if (hostComponent.map.layerIds== "highlightGraphics")       {        hostComponent.map.layers.clear();       }      }      hostComponent.map.infoWindow.closeButton.removeEventListener(MouseEvent.CLICK, onInfoWindowClosed);     }       } //My handler for a mapclick, mapclicking outside a feature with popup configuration will hide popup/infowindow and clear the highlight graphics.    private function onMapClick(event:MapMouseEvent):void    {     for (var i:int = 0; i < event.map.layerIds.length; i++)     {      if (event.map.layerIds== "highlightGraphics")      {       event.map.layers.clear();      }     }     event.map.infoWindow.hide();     event.map.removeEventListener(MapMouseEvent.MAP_CLICK, onMapClick);    } ...

What do you mean by OpenLayers WMS services?? OpenLayers is a JavaScript library to build web maps that can dispaly for example WMS Services. It is possible to use WMS Services in ArcGIS for Flex API (and I assume it's possible in the javascript API as well). It might be possible to add a WMS service to a mxd document and publish it in ArcGIS Server (I'm not really sure), but it would be much better to connect directly to the WMS instead of going through ArcGIS Server. I don't think you can use an ArcGIS Server service in OpenLayers (but actually I have no idea because I don't work with OpenLayers) but you can enable the WMS capability on your ArcGIS Server service and use that WMS service in OpenLayers. ...

I think you can't change that with the compiled version. I'm using the uncompiled version and found out that I had to change the value of the PageTitel property of <s:Application> in index.mxml, and that value in the source code looks hardcoded to me... ... View more

Hi, I'm not sure if there are any ready to use configurable widgets for this, maybe someone else can answer that? But if you can make your own widget it's possible. There are (at least) two roads to go, one way is to go through ArcGIS Server by creating a connection to the database in ArcMap and publish a service that you can query. The other way (that I'm using my self) is to skip ArcGIS Server and retrieve the data directly into the flex appilcation. There are documentation for this here for example. I'm accessing data in a MySQL database using PHP and httpservices, and then creates a graphic layer from it and add it to the map, works fine! ... View more

Hi, the ArcGIS Viewer for Flex is based on the ArcGIS API for Flex. I don't see how your supposed to use the Viewer for Flex together with the JavaScript API. When you download the Viewer for Flex the API for flex is included, you don't have to download the API separately, just set up the config file with your map services. The Error you're getting "Invalid tile service" might be that your using type="tiled" on a mapservice that isn't cached. Try use type="dynamic" or make sure the mapservice is cached. ... View more

I recently tried Alex Jones python script to convert saved graphics from enhaced Draw Widget to shapefiles. I ran into problems when the script is inserting attribute values, I think it was because the fields are all text fields, but some values are not text strings, so I just made sure they are by using str(). Then it works for me. I also made a tool/script for ArcGIS toolbox, where the user can browse for txt-file, output location and coordinate system and run it in ArcGIS instead of running it from a python ide and using hard coded paths. It makes it a bit easier to use, if anyone is interessted here's the toolbox and script. Just unzip it somewhere and then rightclick in your toolbox and choose add tollbox and point to the tbx file you just unzipped. Thanks to Alex for sharing the script! ... View more
