I used David Springs' tool: Export PDF web application and GP service sample from http://www.arcgis.com/home/item.html?id=8f16fdeef39c46b3952002b2d85ea5de.  I loaded the widget in my project and then re-compiled the code.   However, after I 'Generate PDF', I clicked 'Download Map' button, the PDF page: http://stlouis.esri.com/arcgisjobs/exportpdf/exportpdf_gpserver/j02b1cf79bae54815bc3591d57862d4a8/scratch/Map.pdf pops out. However, it is an empty map but only with Miles ruler. I guess this might be due to the API version difference.  Has anyone used this component and is willing to provide his/her advise to debug this problem? Thanks. ... View more

I loaded a component to export map to PDF (async one) from http://www.arcgis.com/home/item.html...f697d9965f1dd7. However, I got a runtime error: TypeError: Error #1009: Cannot access a property or method of a null object reference at WidgetManager.mxml's Line 403,     var widget:IBaseWidget;     widget = modInfo.factory.create() as IBaseWidget;     widget.widgetId = widgetId;   // Line 403 when I clicked the tool's icon to open the widget. Through tracing, I found that widget is null. I believe that the modInfo.factory.create() failed.  How can this problem be solved?  I will appreciate if someone can hint me how to debug this problem.

I want to add a MapMouseEvent in ActionScript.  The code I created is below:   map.addEventListener(MouseEvent.CLICK, myEventHandler);   ......   private function myEventHandler(e:MapMouseEvent):void {  ... } But I received TypeError: Error #1034: Type Coercion failed: cannot convert flash.events::MouseEvent to com.esri.ags.events.MapMouseEvent. How can this bug be fixed?  Thanks. ... View more

I am testing for the solution using ActionScript.  In my test, I tried to covert the code below:   <esri:FindParameters id="myFindParams"         contains="true"         layerIds="[3]"         outSpatialReference="{map.spatialReference}"         returnGeometry="true"         searchFields="[MCN]"         searchText="{fText.text}"  /> to ActionScript code:     var myFindParams:com.esri.ags.tasks.supportClasses.FindParameters = new com.esri.ags.tasks.supportClasses.FindParameters();     myFindParams.contains = "true";     myFindParams.layerIds = "[3]";  // Error 1067     myFindParams.outSpatialReference = "{map.spatialReference}";    // Error 1067     myFindParams.returnGeometry = "true";     myFindParams.searchFields = "[MCN]";    // Error 1067     myFindParams.searchText = "{fText.text}"; But I received 3 Errors (type 1067 Implicit coercion of a value of type String to an unrelated type Array).  How can these errors be corrected?  Thanks. ...

Based Zoom to Found Features http://help.arcgis.com/en/webapi/flex/samples/index.html#/Zoom_to_found_features/01nq0000005n000000/, I created a widget.  It works well except for adding the graphicsLayer on the map.  I run the debug.  From the Expressions window, it shows the values of its graphicsLayer and graphicProvider.  But  the graphicsLyaer does not display.  I wish someone can help for his/her experience.  Thanks. ...

I used the sample: Zoom to Found Features source code at http://help.arcgis.com/en/webapi/flex/samples/index.html#/Zoom_to_found_features/01nq0000005n000000/ I want to retrieve the values of the found feature. In this piece of code private function executeCompleteHandler(event:FindEvent):void { myGraphicsLayer.clear(); myGraphicsLayer.symbol = sfsFind; var resultCount:int = event.findResults.length; if (resultCount == 0) { Alert.show("No record is found. Please change your search."); } else { // add feature as graphic to graphics layer for (var i:int = 0; i < resultCount; i++) { var graphic:Graphic = FindResult(event.findResults).feature; graphic.toolTip = event.findResults.foundFieldName + ": " + event.findResults.value; myGraphicsLayer.add(graphic); // Code I added in order to retrive the values of the feature (where STF, COF, ... are the attribute names) var tempObj:Municipality = new Municipality(); tempObj.STF = event.findResults.STF; tempObj.COF = event.findResults.COF; tempObj.MCN = event.findResults.MCN; tempObj.Type = event.findResults.Type; tempObj.Area = event.findResults.Area; ...... } ...... } } But it does not work. How to revise the code to retrieve the values? Thanks. ... View more
