Hi to All, Please, can somebody point me to the right place, where (in what assembly ?) I can find and use the object structure, used to serialize Web Map as JSON ? I need it in the proxy to add token to secure layers in print task. I'm trying to recreate this object manually according to the definition found here: http://server.arcgis.com/en/server/latest/create-web-apps/windows/exportwebmap-specification.htm But it is long work that sure was already done, and I'm in doubt about it's current and future compatibility with ExportWebMap process. I need object definition to allow Json Serializer / Deserializer to do their work accurately. May be this question was already asked and even answered, but unfortunately I couldn't find anything about it. Thanks in advance. Gennady ... View more

Hi ! I'm using ArcGISDynamicMapServiceLayer (API v.2.4) pointing to the Map service containing 40+ layers. Some of these layers defined visible in the MXD, others - not. I need to show selected features from one of layers. So I do the following:     layerDefs[layerID] = expression;     designLand.visibleLayers = new ArrayCollection([layerID]);     designLand.layerDefinitions = layerDefs;     designLand.dpi = 96;     designLand.imageFormat = "png24";     designLand.imageTransparency = true;     designLand.disableClientCaching = true;         designLand.visible = true;     designLand.alpha = 0.5; It works fine in the development environment, and I can see in the Fiddler the correct request for export . But when the swf is uploaded onto the production server, this request is issued wrong: instead of setting layers=show:layerID (show:37 in my case), it is set to the list of all layers, defined as visible in the MXD. The only difference between two environments: in the dev environment I'm using proxy to access the production services. What may be wrong ?  What should I do to isolate the problem ? Any help will be highly appreciated. Thanks in advance. Regards, Gennady ... View more

Hi ! I need to load one of widgets dynamically (as a response to certain URL parameter). I decided that the most suitable place to do it is HeaderControllerWidget:     if ((ViewerContainer.urlConfigParams.street != null && ViewerContainer.urlConfigParams.house != null) )     {      var addrWidgetID:Number;      var addrWidget:IBaseWidget;      addrWidgetID = ViewerContainer.getInstance().widgetManager.getWidgetId(addrWidgetLabel);      addrWidget = ViewerContainer.getInstance().widgetManager.getWidget(addrWidgetID,true);      return;     } It works fine in IE10, Chrome and FF, but in the IE8/9 the widget is never loaded and cursor stays in the busy state. System is waiting, and when I load this widget manually - it continues to function properly. Here is the link: Test link When cleaning the IE cache, the first run is successful, but only once. I tried to play with cache definitions without any success. Can somebody please shed light on this strainge behavior ? Thanks in advance. Regards, Gennady ... View more

Hi All ! Environment: ArcGIS Server 10.0, Flex viewer 2.4, Flex API 2.4, Flex Builder 4.5 I need to show the exported image of the layer on the map. Here is the code:    private var designLand:ArcGISDynamicMapServiceLayer;    private var layerImage:MapImageLayer;                                                    ......     layerImage = new MapImageLayer();     layerImage.id = "designLand";     map.addLayer(layerImage);     designLand = new ArcGISDynamicMapServiceLayer(landURL);                                                       ......                                                 var pars:ImageParameters = new ImageParameters();     var layerDefs:Array = new Array();     pars.dpi = 96;     pars.extent = map.extent;     pars.format = "png8";     pars.imageSpatialReference = map.spatialReference;     layerDefs[layerID] = expression;  // The list of where conditions     pars.layerDefinitions = layerDefs;     pars.layerIds = [layerID];     pars.layerOption = "show";  // For sure     pars.transparent = true;         pars.width = map.width;     pars.height = map.height;         designLand.exportMapImage(pars,new AsyncResponder(onExportComplete,onExportFault));                                                     .........    private function onExportComplete(img:MapImage, event:MapImageEvent):void    {    // var mi:MapImage = new MapImage();    // mi.extent = map.extent;    // mi.href = img.href;     layerImage.removeAll();     layerImage.alpha = 0.5;    // layerImage.add(mi);     layerImage.add(img);     layerImage.visible = true;    } The image created OK, all MapImage parameters (extent,spatial reference,width,height) seem to be OK, only the initial extent of the MapImageLayer stays default. But image is shown with shift down, under the bottom boundary of the screen. Can somebody please explain, what I'm doing wrong. Thanks in advance. Regards, Gennady ... View more

Hi ! I have the flex application (actually, the modified flex viewer) shown inside the iframe on the other page. When I use wheel to zoom in/out, and the outer page has scroll bar - the wheel event bubbles to this outer page and it is scrolled. I'd like to disable the wheel event propagation when the mouse pointer is over map. Is there simple conventional way to do it ? Thanks in advance. Regards, Gennady ... View more
