Widget is just another name for Module. The BaseWidget class that ESRI uses in FlexViewer extends Module and adds custom fields used in FlexViewer to pass data around. So if you are looking for info on Modules in general, look up how to work with Flex Modules, loading and unloading. This will help you figure out what is happening with widgets in FlexViewer. I don't think the FlexViewer unloads the widgets when they are closed. I think they get saved to a Dictionary object. ... View more

One kind of hacky way to do would probably require that you extend the Map object. Map has a UIComponent that appears to hold the layers. You can rotate this object without rotating the nav tool/logo/scalebar. But, you'd need to reset the x/y and width/height of this UIComponent to avoid having it appear as though your map has been "trimmed". That's the part that would probably require you overriding the updateDisplayList method of Map to make those changes stick, at least for width and height. You can test this out like this. <?xml version="1.0" encoding="utf-8"?> <s:Application xmlns:fx="http://ns.adobe.com/mxml/2009"       xmlns:s="library://ns.adobe.com/flex/spark"       xmlns:esri="http://www.esri.com/2008/ags"       pageTitle="A tiled map service"> <fx:Script>   <![CDATA[    import mx.events.FlexEvent;    protected function map_creationCompleteHandler(event:FlexEvent):void    {     var i:int = 0;     var x:int = map.numChildren;     for (i; i < x; i++) {      if ( getQualifiedClassName(map.getChildAt(i)) == "mx.core::UIComponent") {       // if you extent the Map, you could make a mapRotate field to hold this value       map.getChildAt(i).rotation = -54;       // positioning could be tricky depending on amout rotated       map.getChildAt(i).x -= 50;       map.getChildAt(i).y = map.height/2;       map.getChildAt(i).width = map.getChildAt(i).width * 2;       map.getChildAt(i).height = map.getChildAt(i).height * 10;      }     }     }   ]]> </fx:Script> <s:Group width="800" height="500">   <esri:Map id="map" creationComplete="map_creationCompleteHandler(event)" >    <esri:ArcGISTiledMapServiceLayer url="http://server.arcgisonline.com/ArcGIS/rest/services/World_Street_Map/MapServer"/>   </esri:Map> </s:Group> </s:Application> I haven't gone any further than this to see if it would work. Maybe someone else has a simpler solution. Now that I think about, you could hide the Nav/Scalebar/Logo, just rotate the whole map and then place a separate Nav/Scalebar outside the map. With the 2.0 API, we now have a ScaleBar object that you just set the map for and you're good to go. That's probably an easier solution than trying to fuss with extending the Map. This method is probably easier. <?xml version="1.0" encoding="utf-8"?> <s:Application xmlns:fx="http://ns.adobe.com/mxml/2009"       xmlns:s="library://ns.adobe.com/flex/spark"       xmlns:esri="http://www.esri.com/2008/ags"       pageTitle="A tiled map service"       xmlns:mx="library://ns.adobe.com/flex/mx"> <s:layout>   <s:VerticalLayout /> </s:layout> <s:BorderContainer borderColor="0x000000">   <s:Group id="grpMap"      width="400"      height="400">    <esri:Map id="map"        logoVisible="false"        scaleBarVisible="false"        x="-389"        y="337"        rotation="-54" width="1000" height="1000">     <esri:ArcGISTiledMapServiceLayer url="http://server.arcgisonline.com/ArcGIS/rest/services/World_Street_Map/MapServer" />    </esri:Map>   </s:Group>   <s:Scroller horizontalScrollPolicy="off"      verticalScrollPolicy="off"      viewport="{grpMap}" /> </s:BorderContainer> <s:Group>   <s:layout>    <s:HorizontalLayout />   </s:layout>   <esri:Navigation map="{map}" />   <esri:ScaleBar map="{map}"         verticalCenter="0" /> </s:Group> </s:Application> Still, to implement this, you'd probably want to do some math to size and position the map in the container just right. I'm not sure how simply turn Nav off in the Map either. ... View more

That is odd. Tried adding a rotation to this example http://help.arcgis.com/en/webapi/flex/samples/index.html?sample=TiledMap and it just doesn't like it. Can't even zoom to the layer properly. ... View more

There are a couple of options. In the Flex API, there is a DrawingInfo field for LayerDetails. You can grab the renderer from there. Mr. Scheitlin has a great example of this in his DynamicLegendWidget. If you go through his widget, you can see how he parses the LayerDetails to get this information. ... View more

I tried your code using Flex 3.6 nightly build and it worked fine. So the issue appears to be a 3.5 bug. <mx:HBox xmlns:mx="http://www.adobe.com/2006/mxml"> <mx:Script>   <![CDATA[    import mx.collections.ArrayCollection;       [Bindable]    protected var ac:ArrayCollection = new ArrayCollection([{name:"Bob",                   children:["bobby", "sally", "billy"]},                  {name:"Sarah",                   children:["angie","kelly"]},                  {name:"Sam",                   children:["sammy","roger","troy", "rich"]}]);   ]]> </mx:Script> <mx:ComboBox id="areaCB"      labelField="name"      dataProvider="{ac}" /> <mx:ComboBox id="teamCB"      dataProvider="{areaCB.selectedItem.children}"      labelField="Team" /> </mx:HBox> You're best bet is to either downgrade to 3.4 or move to 3.6. ...

Hi Casey, There is a similar case noted on the Adobe forums with syncing ComboBoxes using SDK 3.5 I can repeat the bug in this thread in the 3.5 SDK that ships with FlashBuilder 4. http://forums.adobe.com/message/2642802 It may be related. Can you provide a sample of the ArrayCollection? I think I still have some nightly builds I can test against. ... View more

You can try calling areaChange on the close event, but I think the issue might be that since you have combobox 2 bound to an object in the selected item of combobox 1, you don't need to make the function call at all. Try removing the areaChange call where you set the dataProvider to null. You shouldn't need it. ... View more

I don't use the FlexViewer Bjorn, but I tried moving away from specific nav tools, like pan/zoom previous/zoom next/zoom out, but one of the first things users ask is, "hey, where is the zoom previous or pan button". I never should have put it in to begin with, but the users want what they want. Personally, I think a single zoom in would be fine, but apparently I'm too minimalist. ... View more

If you're using the where clause, I don't think you need the text property. It's not your error though. <esri:Query id="query" where="STATE_NAME = '{qStateName.text}' and pop1990 &lt; 1000000" returnGeometry="true" outSpatialReference="{map.spatialReference}"> FlashBuilder makes it look like you're passing regular text, but you're really binding it to the input. ...

Use the WGS_1984_Web_Mercator which is wkid 102113 and is compatible with 102100. There was a thread a while discussing this, but I forget where it is now, but I don't think there is an explicit 102100 in ArcMap. ... View more

I use GraphicsLayer for miscellaneous selections, more like stuff where I just want to see a boundary, but don't care too much about the data behind it except maybe a name. I use the FeatureLayer for a couple of items where I can leverage the RelationshipQuery to easily pull in detailed data. I can't tell you how much easier this has made pulling detailed data from SDE tables for me. Previously, I would have had to use a WebService/RemoteObject to hit the SDE directly for table queries. Now that we have access to AMF in the QueryTask which is built into FeatureLayer, it's cut my service calls down drastically. When you do a selection using a FeatureLayer it returns an array of graphics, each with an attribute field. So when I do this AsyncToken(fLayer.selectFeatures(query, "new", new AsyncResponder(response, onFault))); I use this [Bindable] featuresColl:ArrayCollection; // bind this to a DataGrid dataprovider private function response(features:Array, token:Object = null):void { var f:Array = extractAttributesFromFeatures(features); // for loop in previous post featuresColl = new ArrayCollection(f); } Graphics in the FeatureLayer are automatically show on your map and also stored in flayer.selectedFeatures So in comparison flayer.selectedFeatures is equivalent to featureSet.features but there doesn't seem to be an equivalent pointer to featureSet.attributes. I imagine this might be for performance reasons to keep Featurelayer efficient. You can review the FeatureLayerEvent which is the result when using queries with FeatureLayer to see some options http://help.arcgis.com/en/webapi/flex/apiref/com/esri/ags/events/FeatureLayerEvent.html You can see the features array in there and you can also see that you get a FeatureSet when you use fLayer.queryFeatures, but a regular query doesn't show the graphics on the map automatically. ...

Is your ArcGIS Server version 10? Using a FeatureLayer, you can only get symbology back from AGS10. I had this issue when I started using FeatureLayer's before I upgraded my server. ... View more

You're a lifesaver Dasa. Chaning to ROLL_OUT/ROLL_OVER works great. Can't believe I didn't check event targets. Thanks again. ... View more

I'm still not 100% clear on FeatureLayers purpose. It would seem looking at examples it's usefulness is really for editing and time-aware data. I'm sure they've covered it in more detail somewhere, but I may have missed it. If you review this sample, you'll see a quick note about FeatureCollection for FeatureLayer that states you should initialize FeatureCollection on your own. So it's not useful for data binding results of a query. http://help.arcgis.com/en/webapi/flex/samples/index.html?sample=TemporalRenderer_FeatureCollection So far the method I have been using to extract attributes from a FeatureLayer is manually. protected function extractAttributesFromFeatures(features:Array):Array { var f:Array = []; var g:Graphic; for each (g in features) {   f.push(g.attributes); } return f; } Then you can set that result to a Datagrid dataprovider. ...
