There are many incredible flex mapping sites with or without the viewer framework. I dont think there is an advantage or disadvantage to either approach, if you are familiar with flex development. Here is an ESRI blog that has skinned and customised the viewer. The description reads: At the 2011 Esri Developer Summit we presented the "Go Electric" application to demonstrate how easily a Flex programmer could customize and extend the ArcGIS Viewer for Flex The key point here is "how easily a Flex Programmer could customise". http://blogs.esri.com/Dev/blogs/arcgisserver/archive/2012/01/11/Taking-ArcGIS-Viewer-for-Flex-customization-to-the-next-level_3A00_-Go-Electric.aspx If you are serious about learning flex, I think keeping away from the both the viewer and mapping api is a good way to learn the foundations of flex. If you already know flex then you should have the foundations covered. Once you have solid flex foundations you can review the core mapping api and the provided ESRI samples, you can review the viewer and the many widgets, then make an informed decision of what is more suitable. It comes down to your own site specific requirements, and/or personal preference. If you just want to get a site up without learning the ins and outs of flex and are happy with being a "copy and paste ninjas" then the viewer is a good solid choice. You can customise widgets, create your own widgets and as the blog shows, skin the site too. ... View more

Patrick, The code I added was a quick workaraound but not entirely foolproof. If th euser qwuiclky double or triple clicks a selected feature, the vertice's and move handles would still come up. Plus I had some extra requirements oustside of the attribute Inspector that was giving me some grief. So I have come up with a different solution by extending the Editor component. I am in the testing phase at the moment and will post here when finished. Depending on your requirements it may be a better solution. What exactly are you trying to achieve. What is your workflow or use case. If you able post your widget code I can have a look at what you need. ... View more

I have come up with a workaround to this issue. This works for my paticular case as I only need to deal with one feature at a time. This workaround acts like a toggle to show/close the AttributeInpector window. Click once on the feature and thefeature will be selected and have the AttributeInpector shown. Click a second time on the feature and the feature will be de-selected and the AttributeInpector will close. //add listeners when the editor component is created. editor.attributeInspector.addEventListener(AttributeInspectorEvent.SHOW_FEATURE,attribute_showHandler); map.infoWindow.addEventListener(Event.CLOSE,attribute_closeHandler); /** * Removes listener from the attributeInspector's activeFeature. */ protected function attribute_closeHandler(event:Event):void { if (editor.attributeInspector.activeFeature) {   editor.attributeInspector.activeFeature.removeEventListener(MouseEvent.CLICK,attributeFeature_clickHandler); } } /** * Adds listener to the attributeInspector's activeFeature. */ protected function attribute_showHandler(event:AttributeInspectorEvent):void { event.feature.addEventListener(MouseEvent.CLICK,attributeFeature_clickHandler); } /** * Clears the FeatureLayers selection. Clearing the selection will also trigger the attribute_closeHandler. * Workaround to prevent the user moving the features vertices or moving the entire feature. * Without this, the feature will show vertice's on the second click, and the entire graphic will be able to be moved on the third click, * even with editor.updateGeometryEnabled="false". */ protected function attributeFeature_clickHandler(event:MouseEvent):void { featureLayer.clearSelection(); } ...

Hi Sarthak, 1. So my code works for you with SNAP_MODE_ALWAYS_ON? Do you have some tested and working code that you can provide so I can see if it something to do with my set up. 2. I do not get the bold cross on 'shared' vertices where there is a 'T' intersection like in my image. It always wants to snap to the edge and does not find the vertex. If you use the code I provided, the extents go to the polygons in the image. You can test on those polygons. ... View more

It should work with any subclass of com.esri.ags.layers.Layer. I do not have a Bing Maps key so I can not test, but a VETiledLayer is a subclass of Layer. You need to add the layers to 'baseLayers'. My original code is only looking for ArcGISTiledMapServiceLayers. protected function MyMap_creationCompleteHandler(event:FlexEvent):void { baseLayers.push(yourBingLayer); MySlider.minimum = 1; MySlider.maximum = baseLayers.length; MySlider.value = 0; } What is a Feature Service? Do you mean ArcGISDynamicMapServiceLayer or FeatureLayer. Either way they both subclass Layer and will work. The code below now includes an ArcGISDynamicMapServiceLayer and FeatureLayer in the Map. You can manually add the layers to 'baseLayers'. //Manually add to 'baseLayers' baseLayers.push(l5); baseLayers.push(l6); <esri:Map id="MyMap" creationComplete="MyMap_creationCompleteHandler(event)"> <esri:ArcGISTiledMapServiceLayer id="l0" url="http://server.arcgisonline.com/ArcGIS/rest/services/ESRI_StreetMap_World_2D/MapServer" alpha="1"/> <esri:ArcGISTiledMapServiceLayer id="l1" url="http://server.arcgisonline.com/ArcGIS/rest/services/NGS_Topo_US_2D/MapServer" alpha="0"/> <esri:ArcGISTiledMapServiceLayer id="l2" url="http://server.arcgisonline.com/ArcGIS/rest/services/ESRI_Imagery_World_2D/MapServer" alpha="0"/> <esri:ArcGISTiledMapServiceLayer id="l4" url="http://server.arcgisonline.com/ArcGIS/rest/services/NGS_Topo_US_2D/MapServer" alpha="0"/> <esri:ArcGISDynamicMapServiceLayer id="l5" url="http://sampleserver1.arcgisonline.com/ArcGIS/rest/services/Demographics/ESRI_Population_World/MapServer" alpha="0" /> <esri:FeatureLayer id="l6" definitionExpression="TYPE='city' AND POP1990 &gt; 50000"         outFields="[CITY_NAME,CAPITAL,DIVORCED,POP1990,MALES,FEMALES]"         url="http://sampleserver1.arcgisonline.com/ArcGIS/rest/services/Specialty/ESRI_StatesCitiesRivers_USA/MapServer/0" alpha="0">   <esri:renderer>    <esri:UniqueValueRenderer attribute="CAPITAL">     <esri:defaultSymbol>      <esri:SimpleMarkerSymbol color="0xCCCCCC"             size="12"             style="x"/>     </esri:defaultSymbol>     <esri:UniqueValueInfo value="Y">      <esri:symbol>       <esri:CompositeSymbol>        <!-- Star in circle -->        <esri:SimpleMarkerSymbol color="0xFF0000"               size="22"               style="circle"/>        <esri:SimpleMarkerSymbol color="0xFFFFFF"               size="20"               style="triangle"/>        <esri:SimpleMarkerSymbol angle="180"               color="0xFFFFFF"               size="20"               style="triangle"/>       </esri:CompositeSymbol>      </esri:symbol>     </esri:UniqueValueInfo>     <esri:UniqueValueInfo value="N">      <esri:symbol>       <esri:SimpleMarkerSymbol color="0xFF0000"              size="18"              style="diamond"/>      </esri:symbol>     </esri:UniqueValueInfo>    </esri:UniqueValueRenderer>   </esri:renderer> </esri:FeatureLayer> </esri:Map> ...

This looks great. I'm definitely looking forward to trying it out.  Will it work with SFV 2.3.1? Jay, I have not tested with 2.3.1 It was built with 2.2 ... View more

I am running version 2.3.1 of the viewer, ArcGIS Server 9.3.1, and an SDE database model.  There are no joins on any of the layers. Again, version 1.0 worked fine. Hi Curtis, Getting unique values now uses objectids in the querytask, which allows for the paging in the query. Objectids are new with ArcServer 10.xx. Thats why 9.3 data isnt being returned. ...
