This is regarding Robert Scheitlin's Dynamic Legend widget located here.  I am using the 3.2 uncompiled version.  My operational layers seem to be displaying in no particular order in the widget.  I'm sure it's based on something, but right now it seems quite random. Can anyone explain the logic behind the sorting of items in the Dynamic Legend widget, and how/where I might go about changing or controlling it?  I'd really like to have them in the order they are listed in the Map Switcher widget.

How do I use esri:WeightedClusterer to cluster graphics and get a popup like the image below (which is from an operational layer in the flex viewer)?  In my app, I don't get any popups for the cluster symbols, only for the flares. [ATTACH=CONFIG]25032[/ATTACH] Thanks, Aaron ... View more

I have 2 widgets that need to share an arraycollection.  I want to create the collection once in which ever widget initializes first, and then store it for them both to use from that point forward.  I've looked at DataManager and I can see how I would share data in an event driven way. What I don't see is a way to store data in DataManager when either widget initializes and 1) check for the data's existence when the second widget loads so I don't have to create it again, and 2) how I would retrieve the stored data in the second widget if I could check for its existence in DataManager.  For reference, the driving force here is that I have comboboxes in each widget that need to use the same data. Can anyone explain how I would share a single collection of data between widgets that only gets initialized once?  Any help would be greatly appreciated. Thanks, Aaron ... View more

I'm clustering 20k+ points over a basemap. This causes the browser/player to hang with a blank base map for several seconds while it does the math, I guess. Then I get a nice set of clustered graphics on the map with no latency thereafter. This is of course driving me, and my boss, insane due to the 10+ second wait. So I've used mobilecomponents.swc to thrown up a BusyIndicator which I would like to turn off when clustering completes. Does any one know if there is a way to listen to clustering? I did not see any relevant events in the API ref, but I am new to this. I also tried adding a preloader, but it completes before any of this latency begins, and actually makes the overall spinup time increase. It's probably worth mentioning that this is in a Flash Builder project with the 3.2 flex viewer source. The only mod to the source is adding the following code to index.mxml. I plan to make it prettier than this if I can find a way to turn it off after the clusters are visible. I also built a custom query widget, but it is not loaded when this latency occurs.     </viewer:ViewerContainer>     <s:BusyIndicator id="busyIndicator"                            symbolColor="red"                            visible="true"                            width="200"                            height="200" /> Any help or guidance would be greatly appreciated.

I would like to have a combobox use a graphic's geometry as it's value. I don't know if this is even possible, and I can't find anything definitive on the subject. I'm hoping some of the geniuses here can shed some light on the subject. Right now I have a combobox that I have populated from an array collection built by a querytask response. Technically it is 4 querytask responses in array collections that are merged into a single array collection when all the tokens light up true. Then this single array collection is assigned as the dataprovider for the combobox. I'm setting up the collection in this manner: collection.addItem({label:fieldValue, data:graphic.geometry}) // where field value is a string and then assigning it like this after concatenating the collections: cmb1.labelField = "label"; cmb1.dataProvider = mergedCollection; // where mergedCollection is a concatenation of collections as created above The problem is that when I then select an item from the seemingly populated combobox and submit the query I get the following: [RPC Fault faultString="Unable to complete operation." faultCode="400" faultDetail="'where' parameter not specified 'objectIds' parameter not specified 'time' parameter not specified 'geometry' parameter not specified 'text' parameter not specified Unable to complete Query operation."] Here is a sample of my code. The whole process of populating the combobox starts in initCombo(). Hopefully you can follow it from there. I also included doQuery() which is called from a button after the user picks something from the combobox. private function initCombo():void { var baseURL:String = "http://myserver/ArcGIS/rest/services/mystuff/MapServer/" var tokenCounter:int = 0; // tokens is an array collection of objects // only feature layers 7 to 10 are relevant for this combobox for (var i:int = 7; i < 11; i++) {   queryTask.url = baseURL + i.toString();   queryTask.execute(query, new AsyncResponder(onResult, onFault, tokens.getItemAt(tokenCounter)));   tokenCounter++; } function onResult(featureSet:FeatureSet, token:Object = null):void {   for each (var graphic:Graphic in featureSet.features)   {    var fieldValue:String = token.name + " " + graphic.attributes["OBJECTID_1"].toString();    token.collection.addItem({label:fieldValue, data:graphic.geometry});   }     for each (var item:Object in tokens)   {    // probably a better way to get a handle back to global collections than this    if (item.name == token.name)    {     item.collection = token.collection;     item.completed = true;     break;    }   }     // if all the tokens are true, merge the collections into one   if (checkTokens()){    // collections is an array containing the array collections so I can iterate through them    for (var i:int = 0; i < collections.length; i++)    {     mergedCollection = new ArrayCollection(result.source.concat(collections.source));    }    cmb1.labelField = "label";    cmb1.dataProvider = mergedCollection;   } } function onFault(info:Object, token:Object = null):void {   Alert.show(info.toString(), "Query Problem"); } } private function checkTokens():Boolean { for (var i:int = 0; i < tokens.length; i++) {   if (!(tokens.completed))   {    return false;   } } return true; } private function doQuery():void { graphicsLayer.clear(); query.where = ""; // I thought this would be the geometry returned by the query query.geometry = cmb1.selectedItem.value; queryTask.execute(query, new AsyncResponder(onResult, onFault)); function onResult(featureSet:FeatureSet, token:Object = null):void {   var graphicsExtent:Extent = GraphicUtil.getGraphicsExtent(featureSet.features);   if (graphicsExtent)   {    map.extent = graphicsExtent;   }   graphicsLayer.graphicProvider = featureSet.features; } function onFault(info:Object, token:Object = null):void {   Alert.show(info.toString(), "Query Problem"); } } This is the MXML for my combobox: <s:ComboBox id="cmb1" x="179" y="205" labelField=""/> Any help would be greatly appreciated.
