Try using the firebug extension in Firefox to see if the queries to the map service are being sent and if they are is a response is being received from the server. You might be getting timeouts when waiting for the map images to be received when the extent is updated. ... View more

maybe you can adopt this to help you. in the addLayer funtion you will need to add code to loop through MyDynamicMapService.visibleLayers and see if the layerID is present. add this line to your existing code: addLayer(getLayerInfoID(MyDynamicMapService.layerInfos,"MyLayerName")); //Add these functions to your code             private function addLayer(layerInfo:LayerInfo):void             {                                 //add code here to loop through MyDynamicMapService.visibleLayers                                //This line adds the layer                                 MyDynamicMapService.visibleLayers.addItem(layerInfo.id);                 }             //given an array of layerinfos and a layername returns the layer ID             private function getLayerInfoID(layerInfos:Array, layerName:String):LayerInfo             {                 var info:LayerInfo;                 for (var i:int = 0; i < layerInfos.length; i++)                 {                     if (layerInfos.name == layerName)                     {                         info = layerInfos                     }                 }                 return info             } ...

Thanks Dasa I accomplished this in pretty much the same way. I'm posting the code below in case it helps anybody but I think it does the same as what you posted but in a much less elegant way. The code takes a result set that is returned from a relationship query. this result set has only one feature set, a collection of line features. Each feature has an attribute called Bearing that has values in decimal degrees. This attributed is then formatted formatted to bearing distance format and then added to an array collection that is bound to a data grid.             private function onRelatedLines(results:Object, token:Object = null):void             {                 var intBearing:Number;                 var strPrefix:String;                 var steSuff:String;                 var strDegrees:String;                 var strMinutes:String;                 var strSeconds:String;                 for each( var RelatedResultFS:FeatureSet in results)                 {                     graphicsLayer.graphicProvider = RelatedResultFS.features;                     for each( var RelateResultGraphic:Graphic in RelatedResultFS.features)                     {                         intBearing = RelateResultGraphic.attributes.Bearing;                         if (intBearing >= 0 && intBearing <= 360)                         {                             if (intBearing >= 0 && intBearing < 90)                             {                                 strPrefix = "N";                                 steSuff = "E";                                 intBearing = intBearing;                             }                             else if (intBearing >= 90 && intBearing < 180)                             {                                 strPrefix = "S";                                 steSuff = "E";                                 intBearing = 180 - intBearing;                             }                             else if (intBearing >= 180 && intBearing < 270)                             {                                 strPrefix = "S";                                 steSuff = "W";                                 intBearing = intBearing - 180;                             }                             else if (intBearing >= 270 && intBearing <= 360)                             {                                 strPrefix = "N";                                 steSuff = "W";                                 intBearing = 360 - intBearing;                             }                             strDegrees = String(Math.floor(intBearing)) + String.fromCharCode(186);                             strMinutes = String(Math.floor((intBearing - Math.floor(intBearing))* 60)) + "'";                             strSeconds = String(Math.floor((((intBearing - Math.floor(intBearing))* 60) - Math.floor((intBearing - Math.floor(intBearing))*60))*60*100)/100) + "''";                             RelateResultGraphic.attributes.Bearing = strPrefix + strDegrees + " " + strMinutes + " " + strSeconds + " " + steSuff;                                                         arrcParcelLinework.addItem(RelateResultGraphic.attributes)                         }                     }                 }             } ...

Can you have your IT dept. monitor the firewall to see if anything gets logged? Your cross domain looks to be the same as the one I use on our public server except I don't have encoding="UTF-8" in the header ... View more

I am not familiar with the proxy.ashx file. Where is it located? I had issue setting this up using the tokens/gettoken.html page. My issue was I didn't have url rewiting set up properly on the web server for arcgis/tokens*. There was also something about about specifying https:// as well as http:// in the rule. ... View more

I don't think you can use the identify widget to consume a web service or use one of its operations. You would have to use flex to consume the web service. There is a tool that will automatically generate the classes you need to consume the service and its operations click Data>Connect to Data/Service then choose web service. From there you give the url and the operations you want to use. You will manually have to call the resulting classes from code ... View more

I haven't worked with clustering but Mansour wrote a post about extending the flare symbol class that might be of some use to you. http://thunderheadxpler.blogspot.com/2010/08/image-flare-symbol-for-clustered.html ... View more

OK figured it out. When a group layer is toggled on all sub layers are turned on automatically. If this is not the desired behavior do not toggle on the group layer, instead toggle on just the desired sub layers. Sub layers will be visible even when the parent layer is not part of the visibleLayers array. I didn't see this documented anywhere and it is different behavior than ArcMap. ... View more

Thanks you this was killing me. I couldn't figure out why sublayers that were not on by default kept appearing when I toggled a group layer. I found no documentation about this and it is different than how ArcMap works. ... View more

Andrew Just an FYI and for the sake of anybody else coming across this thread. I figured out why I'm getting inaccurate measurements when I do my calculations and it should have been obvious. It is because the map service I'm measureing against is Web Mercator projection which is horrible for distance distortions, especially at higher latitudes. Continuously reprojecting a polyline as it's drawn is not practical so I'm kind of cheating and using an approximate distortion scale of 20%. It's crude but it seems to work so far. I'm sure somebody has worked out a formula for my latitude I sure but I can't find it. Thanks ... View more

Thanks for your help guys. I've figured out how to get the coordinates in real time using the mouse move event and I tried to do the calculations to get distance. I was using good old Pythagoras, d= �??(x2 - x1)² + (y2 - y1)² but it doesn't appear to be accurate enough and my distances are always several meters too large. Does anybody have a more accurate formula? I'm sure it will involve lots of high school trigonometry that I have long since forgotten but if anybody has any pointers please let me know. Thanks again ... View more
