The API docs can give you some insight on when you would use FeatureLayer http://help.arcgis.com/en/webapi/flex/apiref/com/esri/ags/layers/FeatureLayer.html The feature layer can be used to display features from one single layer of either a Feature Service or a Map Service. The layer can be either a (spatial) layer or a (non-spatial) table. The features in a FeatureLayer can be edited if it is based on a Feature Service. If the layer supports attachment, the layerDetails (or tableDetails) "hasAttachment" property will be true. If the feature layer is editable and has attachment, you can also add and delete attachments. So if you want to do editing, use temporal features, FeatureLayer is your choice. FeatureLayer is essentially a GraphicsLayer with some sugar, i.e., built in QueryTask. You wouldn't use DynamicMapServiceLayer directly, as it is a base class. http://help.arcgis.com/en/webapi/flex/apiref/com/esri/ags/layers/DynamicMapServiceLayer.html But what it does allow you to do is something like if (layer is DynamicMapServiceLayer) {     // do something to apply to all subclasses } //as opposed to writing if (layer is ArcGISDynamicMapServiceLayer || layer is ArcGISImageServiceLayer || layer is ArcIMSMapServiceLayer || layer is GPResultImageLayer || layer is WMSLayer) {     // do the same thing } You can view the Layers in the layers package here, each with some some descriptions http://help.arcgis.com/en/webapi/flex/apiref/com/esri/ags/layers/package-detail.html ...

I don't have a widget, but I did make a Magnify component for my projects that could pretty easily be turned into a widget. This is the Skinnable Component https://gist.github.com/753059 This is the TitleWindow with some methods to pass the MagnifyWindow when you move it around the screen. https://gist.github.com/753061 It basically accepts your main map as the source map to know the current location of the window on the screen. You add a "Detailed" layer, in my case I use some high resolution imagery we have in-house. You can then add "Operational" layers to view on top of your "Detailed" layer. All layers have to be Dynamic so that you can zoom in as far as you want. I'll clean it up and add it to my FlexMapTools library at some point, but pretty busy this time of year. Hope that helps. ...

You can add an eventListener to each graphic in the arraycollection,then when it gets clicked, save that item so that when you click on delete you can find it in the ArrayCollection. So, something like this. var graphic:Graphic = event.currentTarget as Graphic; var i:int = arrayCollection.getItemIndex(graphic); arrayCollection.removeItemAt(i); ... View more

I have only done some CF work in my home dev environment, but using CF remote calls in with the current Flex API/Flexviewer should be no different than you did with the 1.x version. Add your CF destinations to your services-config.xml and Flex will handle the rest. In Flashbuilder, if you like the code generation, there is a Connect to ColdFusion option to connect to remote services. ... View more

I had the odd issues when I started working with FeatureLayer. Try listening on the rollOver/rollOut events instead, see if that helps. http://forums.arcgis.com/threads/8747-Odd-behavior-of-FeatureLayer-and-MapPoint-graphics ... View more

Flex can't access local resources in that manner and although AIR can access some local resources, as far as I know com/serial ports is not one of them. You may be able to write a small app in say Java that can write to the SQLlite db that AIR can read instead of having to send a query off to a server. If this is a web app, you're method should work. ... View more

My java experience is pretty limited to just database access and queries. To access SQL Server, you'll need the sqljdbc4.jar from Microsoft. One thing I am doing in that query is turning my results into a custom object I call FlowControl, which is a pretty simple Java object, but what it allows me to do is quickly serialize those objects in Flex by adding this metadata tag to a class [RemoteClass(alias="SewerDb.dto.FlowControl")] public class FlowControl... So your Flex object matches your Java object. There are lots of materials on Adobe's website and elsewhere on using BlazeDS with Flex. http://www.adobe.com/devnet/livecycle/articles/blazeds_spring.html One book that I really like that just recently went into print is Flex On Java, which covers the subject really well. If however, you are like me and prefer working in a .NET environment, you can use WebOrb for .NET, which is a great solution for tasks like this. A great benefit of WebOrb is the WebOrb console which will let you test your functions as well provide you the Actionscript code you would need to use the functions. It has fantastic code generation tools that you can use to learn from. Using RemoteObjects requires slightly more setup initially to access backend data, but it absolutely worth it in the end. We have one function to perform flow tracing that can return a few thousand records that is done via a WebOrb AMF endpoint, and as a regular WSDL web service it took up to 2 minutes to return results and we can now show the query results in less than 10 seconds. ...

Has anyone been able to find a work around for this. The main complaint I am getting from users is the inability to zoom in further than they can now, especially because this functionality worked in the 1.3 API. Do I need to completely remove my tiled services from the project to do this? It used to be that I could disable the map.lods, turn off tiled services and zoom in on the map as far as I wanted. Now I can't do that. Any help would be appreciated here, or how can we file this as a bug? ... View more

Does the data in the tables you are querying via BlazeDS match fields in your map service? For example, what I do is use BlazeDS/WebOrb to query various tables of land use and property information, get back a list of say parcel numbers, then I perform a QueryTask on the map service of parcels using those parcel numbers. For various reasons, this data sits outside an SDE, but I can use the remote service to tie everthing together. I've gotten very comfortable working with my data in this manner and because I can customize the queries to my hearts content, I actually prefer it to Relationship queries provided by the ESRI Flex API. For example, I have a java query in BlazeDS to queries some Flow data for our sewer system. public static ArrayList<FlowControl> getFlowControlList() { ArrayList<FlowControl> flows = new ArrayList<FlowControl>(); ResultSet resultSet; try {   connection = ConnectionHelper.sdeConnection();   Statement stmt = connection.createStatement();   String sql = "SELECT CSDAssetID, CSDFeatureID, '' AS PipeCSDAssetID, '' AS PipeCSDFeatureID, UpstreamPipeCSDAssetID, UpstreamPipeCSDFeatureID, "     + "DownstreamPipeCSDAssetID, DownstreamPipeCSDFeatureID, FlowControlInputDate, FlowAllowed, FlowControlPosition, Subtype "     + "FROM sde.SSCOMPLEXFLOWCONTROLHISTORY AS cf "     + "WHERE (FlowControlInputDate = "     + "(SELECT MAX(FlowControlInputDate) AS Expr1 "     + "FROM sde.SSCOMPLEXFLOWCONTROLHISTORY AS cf2 "     + "WHERE (CSDAssetID = cf.CSDAssetID) AND (CSDFeatureID = cf.CSDFeatureID))) "     + "UNION "     + "SELECT CSDAssetID, CSDFeatureID, PipeCSDAssetID, PipeCSDFeatureID, '' AS UpstreamPipeCSDAssetID, '' AS UpstreamPipeCSDFeatureID, "     + "'' AS DownstreamPipeCSDAssetID, '' AS DownstreamPipeCSDFeatureID, FlowControlInputDate, FlowAllowed, FlowControlPosition, Subtype "     + "FROM sde.SSFLOWCONTROLHISTORY AS f "     + "WHERE (FlowControlInputDate = "     + "(SELECT MAX(FlowControlInputDate) AS Expr1 "     + "FROM sde.SSFLOWCONTROLHISTORY AS f2 "     + "WHERE (CSDAssetID = f.CSDAssetID) AND (CSDFeatureID = f.CSDFeatureID))) "     + "ORDER BY CSDAssetID";   resultSet = stmt.executeQuery(sql);   while (resultSet.next()) {    FlowControl flow = new FlowControl();    flow.setCsdAssetId(resultSet.getString(CSD_ASSET_ID));    flow.setCsdFeatureId(resultSet.getString("CSDFeatureID"));    flow.setDownstreamPipeCsdAssetId(resultSet      .getString("DownstreamPipeCSDAssetID"));    flow.setDownstreamPipeCsdFeatureId(resultSet      .getString("DownstreamPipeCSDFeatureID"));    flow.setFlowAllowed(resultSet.getBoolean("FlowAllowed"));    flow.setFlowControlInputDate(resultSet      .getDate("FlowControlInputDate"));    flow.setFlowControlPosition(resultSet      .getString("FlowControlPosition"));    flow.setPipeCsdAssetId(resultSet.getString("PipeCSDAssetID"));    flow.setSubType(resultSet.getString("Subtype"));    flow.setUpstreamPipeCsdAssetId(resultSet      .getString("UpstreamPipeCSDAssetID"));    flow.setUpstreamPipeCsdFeatureId(resultSet      .getString("UpstreamPipeCSDFeatureID"));    flows.add(flow);    System.out.println("FlowList = " + flow.getCsdAssetId() + " : "      + flow.getCsdFeatureId());   } // end while statement } catch (SQLException ex) {   System.out.println(ex.getMessage()); } // end try-catch block finally {   closeConnection(); } return flows; } Then in my Flex project, I can use the ArrayList as a DataProvider for a table or iterate the list to build a query that will use an existing map service in my application. ...

Sorry, I meant to remove those comments. You just need to use the event.mapPoint as the geometry for your IdentifyParameters you send to your IdentifyTask. http://help.arcgis.com/en/webapi/flex/apiref/com/esri/ags/tasks/supportClasses/IdentifyParameters.html idParams.geometry = event.mapPoint; Hope that helps. ...

This is probably how I would handle it. You can create one function to capture all the button clicks and let that function handle what happens. You can also make sure the Identify Task will not fire when you just want to zoom or pan. <fx:Script> <![CDATA[   protected static const IDENTIFY:String = "identify";     protected function activateIdentify():void {    map.addEventListener(MapMouseEvent.MAP_CLICK, onMapClicked_handler);   }     protected function onMapClicked_handler(event:MapMouseEvent):void {    var idParams:IdentifyParameters = new IdentifyParameters();    idParams.layerIds = [layerId];    idParams.tolerance = 2;    idParams.returnGeometry = true;                                       // grab your event.mapPoint and use it for your Identify tool    idParams.geometry = event.mapPoint;    idParams.width = _map.width;    idParams.height = _map.height;    idParams.mapExtent = _map.extent;    idParams.spatialReference = _map.spatialReference;    idParams.layerOption = "all";    var idSym:SimpleMarkerSymbol = new SimpleMarkerSymbol("x", 12, 0xFF0000);    var g:Graphic = new Graphic(event.mapPoint, idSym);    // idLayer is a graphicsLayer I use to    // just show where I clicked on the map    idLayer.clear();    idLayer.add(g);    idTask.url = "urlForIdentifyTaskToUse";    idTask.execute(idParams, new AsyncResponder(onIdentifyResults_handler, onFault, g));   }   protected function removeMapListener():void {    if (map.hasEventListener(MapMouseEvent.MAP_CLICK))     map.removeEventListener(MapMouseEvent.MAP_CLICK, onMapClicked_handler);   }     protected function navigate(type:String):void {    removeMapListener(); // you can reuse this function for each of your other button clicks    switch(type) {     case NavigationTool.ZOOM_IN:      navTool.activate(NavigationTool.ZOOM_IN);      break;     case NavigationTool.ZOOM_OUT:      navTool.activate(NavigationTool.ZOOM_OUT);      break;     case NavigationTool.PAN:      navTool.activate(NavigationTool.PAN);      break;     case IDENTIFY:      activateIdentify();      break;    }   } ]]> </fx:Script> <s:HGroup> <s:Button label="Zoom In" click="navigate(NavigationTool.ZOOM_IN)"/> <s:Button label="Zoom Out" click="navigate(NavigationTool.ZOOM_OUT)"/> <s:Button label="Pan" click="navigate(NavigationTool.PAN)"/> <s:Button label="Identify" click="navigate(IDENTIFY)"/> </s:HGroup> ...
