I found this code very helpful. I have added a text box and area text box to allow for a subject and comment block to be added to the email. I know that my coding is very crude, and I'm looking for input on how to better write it. <?xml version="1.0" encoding="utf-8"?> <viewer:BaseWidget xmlns:fx="http://ns.adobe.com/mxml/2009"        xmlns:s="library://ns.adobe.com/flex/spark"        xmlns:mx="library://ns.adobe.com/flex/mx"        xmlns:viewer="com.esri.viewer.*"> <fx:Script>   <![CDATA[    import com.esri.ags.geometry.MapPoint;    import com.esri.ags.utils.WebMercatorUtil;       import mx.controls.Alert;       [Bindable]    private var EmailComment:String;          // Sends data to email file     // Ref: http://forums.arcgis.com/threads/41459-Create-Email-with-Hyperlink-to-share-map-extent     // Ref: http://stackoverflow.com/questions/6841136/mailto-with-attachments-in-flex-or-air-applications     // Ref: http://zoomquiet.org/res/scrapbook/ZqSKM/data/20100419224556/          private function mailme():void    {     var currentCenter:MapPoint = (map.extent.center) as MapPoint;     var u:String = "";      u+= "mailto:[email protected]";      u+= "?";      u+= "subject=";      u+= emailSubject.text;      u+= " ";      u+= "&body=http://url/siteweb/?center="       + myDegreeFormatter.format(currentCenter.x)       + ","       + myDegreeFormatter.format(currentCenter.y)       + "%26"       + "scale="       + Math.round(map.scale)       + "%0D%0A" + "%0D%0A" //Creates two blank lines       + emailComment.text;      var url:URLRequest= new URLRequest(u);      navigateToURL(url);    }       private function getURLParameters():Object    {     var result:URLVariables = new URLVariables();         try     {      if (ExternalInterface.available)      {       // Use JavaScript to get the search string from the current browser location.       // Use substring() to remove leading '?'.       // See http://livedocs.adobe.com/flex/3/langref/flash/external/ExternalInterface.html       var search:String = ExternalInterface.call("location.search.substring", 1);       if (search && search.length > 0)       {        result.decode(search);       }      }     }     catch (error:Error)     {      Alert.show(error.toString());     }         return result;    }       private function setMapLocation():void    {     var params:Object = getURLParameters();     if (params["ll"])     {      var latlong:Array = String(params.ll).split(",");      if (latlong.length == 2)      {       map.centerAt(new MapPoint(latlong[1], latlong[0]));      }     }     if (params["scale"])     {      map.scale = params.scale;     }    }   ]]> </fx:Script> <fx:Declarations>   <mx:NumberFormatter id="myDegreeFormatter"        precision="0"        useThousandsSeparator="false"/> </fx:Declarations> <viewer:WidgetTemplate id="passURL"  widgetTitle="Pass URL" width="100%" height="100%">     <s:VGroup id="groupURL">          <s:Label     text="Subject: "/>    <s:TextInput id="emailSubject"/>    <s:Label     text="Comment: "/>    <s:TextArea id="emailComment"     maxChars="250"/>    <s:Button click="mailme()"        fontSize="12"        fontWeight="bold"        label="Report Error"/>      </s:VGroup>   </viewer:WidgetTemplate> </viewer:BaseWidget> ...

I think I found the place in the code, similar to your example but with some changes. From what I gather I can use the string.replace as a starting point for my function. Since the repl parameter in the .replace can also be a function. See below, sound correct? if (queryLayer)     {      var query:Query = new Query();      var myPattern:RegExp = /\[value\]/g;      var expr:String;           // adds quotes to the string to be used for SQL query      value = value.replace("'","''");      expr = queryExpr.replace(myPattern, mySubStringFunctionResult);      query.where = expr;      query.outSpatialReference = map.spatialReference;      if(queryDefExpr != "")       queryLayer.definitionExpression = queryDefExpr;      queryLayer.queryFeatures(query, new AsyncResponder(onResult, onFault, queryFields));      showMessage(loadingLabel, true);      showStateResults(); ...

I am encountering a problem where say I select a feature and the results appear in the data grid. If I then select another feature (tool still active) the results in the data grid are not updated until I hover over the record. What I need is a event listener that listens for each new redraw and refreshes the results. My question is where would I put this in the code? Thanks ... View more

Ok, so some of the widget is working however still get NaN (not a number) as shown here. Any ideas to why? [ATTACH=CONFIG]11615[/ATTACH] ... View more

UPDATE: Figured out what was effecting the coordinates...

UPDATE: I created a new flex viewer with the coordinate menu widget, Vancouver now shows up correctly. X: -13706323.186011488 Y: 6320134.462034756 So something is wrong with my original flex viewer, if you have any ideas of what to fix that would be great. ... View more

I get the following "NaN" in all boxes. Yet I still have Lat / Long being displayed in the bottom left corner of the map. I am using the geometry service that comes default with this widget, if I use my own service or another esri geometry service it says cannot find projection.... Any ideas on what is wrong. I am using the correct WKID's for my Coordinate systems drop down. And my .mxd was projected to WGS 1984 Web Mercator (Auxiliary Sphere).  [ATTACH=CONFIG]11603[/ATTACH] UPDATE: I turned off all basemaps and left only my operational layer, the tool now somewhat works. I think it has to do with my projection of my .mxd and that of ESRI basemaps. Does it Matter that I am using WGS 1984 Web Mercator (Auxiliary Sphere) instead of just WGS 1984 Web Mercator? One other thing to note is that the Lat/Long still does not show up [ATTACH=CONFIG]11604[/ATTACH] ... View more

You can try something like this featureLayer.minScale = 100000; <!--Min scale at which appears--> featureLayer.maxScale = 0; or Within the declarations tags <esri:GraphicsLayer id="myGraphicsLayer" minScale="1500000"/> Go here for overall understanding http://resources.esri.com/help/9.3/arcgisserver/apis/flex/apiref/com/esri/ags/layers/Layer.html#isInScaleRange ...

@KenBuja OK so I was able to get it to run without errors using the code you provided. I added dg.addEventListener(ListEvent.ITEM_CLICK, dg_ItemRollOver, false, 0, true); dg.addEventListener(ListEvent.ITEM_ROLL_OUT, dg_ItemRollOut, false, 0 ,true); dg.addEventListener(ListEvent.ITEM_ROLL_OVER, dg_ItemRollOver, false, 0, true); as well as the following code. I think there is something wrong in my function findGraphicByAttribute(attributes:Object):Graphic but I'm not to sure. The most frustrating thing is the first part of the code works (the mouse events) but not the second half... any thoughts would be most appreciated. //Creates graphic for each point, adds attribute data for each point to array           var results:ArrayCollection = new ArrayCollection;                     function onResult(featureSet:FeatureSet, token:Object = null):void           {            if (featureSet.features.length > 0)            {             for each (var myGraphic3:Graphic in featureSet.features)             {              //Adds a mouseover event for the graphic              myGraphic3.addEventListener( MouseEvent.MOUSE_OVER, onMouseOver );              myGraphic3.addEventListener( MouseEvent.MOUSE_OUT, onMouseOut );                           myGraphic3.symbol = resultsSymbol;              myGraphicsLayer.add(myGraphic3);              results.addItem(myGraphic3.attributes);              map.addLayer(myGraphicsLayer);                           dg.visible = true;              dg.dataProvider = results;                           function onMouseOver( event : MouseEvent ) : void              {               var graphic : Graphic = Graphic( event.target );               graphic.symbol = highlightSymbol;                             for each( var attributes : Object in dg.dataProvider )               {                if (attributes === graphic.attributes)                {                 dg.selectedIndex = (dg.dataProvider as ArrayCollection).getItemIndex(attributes)                     }               }                        dg.scrollToIndex(dg.selectedIndex);              }                           function onMouseOut( event : MouseEvent ) : void              {                                Graphic( event.target ).symbol = resultsSymbol;                          dg.selectedIndex = -1;                  }                          function dg_ItemRollOut(event:ListEvent):void              {               findGraphicByAttribute(event.itemRenderer.data).symbol = resultsSymbol;              }                           function dg_ItemRollOver(event:ListEvent):void              {               findGraphicByAttribute(event.itemRenderer.data).symbol = highlightSymbol;              }                           function findGraphicByAttribute(attributes:Object):Graphic               {               for each (var graphic:Graphic in myGraphicsLayer.graphicProvider)              {               if (graphic.attributes == attributes)               {                return graphic;               }              }              return null;              }             }                          } ...

So I have been still playing around with this... I have added the following to the datagrid itemRollOut="onItemRollOver(event)" itemRollOver="onItemRollOut(event)"> I now get the following error Type 1180: Call to a possibly undefined method onItemRollOut. 1180: Call to a possibly undefined method onItemRollOver. Both of these are defined as functions above... I have read that this error can mean that you have not imported all the necessary classes. I have double checked and looks like I have them all. I was able to find this forum that is what I am trying to do. But they still have onItemRollOut defined the same way... This code also has similar functionality to what I am looking for. ... View more
