Hi Tom, Let me give it one more try and be thorough. Please find all the files used below for this issue. The data is retrieved and Excel will open. The problem is, Excel is opened without any data. Code starts here ====================== I will provide all my code here: Flex datagrid page: <?xml version="1.0" encoding="utf-8"?> <mx:Canvas xmlns:mx="http://www.adobe.com/2006/mxml";> <mx:Script> <![CDATA[ import mx.collections.ArrayCollection; import mx.controls.Alert; import mx.rpc.events.FaultEvent; import mx.rpc.events.ResultEvent; [Bindable] private var roResults:ArrayCollection; private function buttonHandler():void { roWildcard.getAllAsStruct(); } private function resultHandler( event:ResultEvent ):void { roResults = new ArrayCollection( event.result as Array ); } private function faultHandler( event:FaultEvent ):void { Alert.show( event.toString(), "Remote Object Fault" ); } private function test():void{ exportManager.exportToExcel("" + "" + "The application has successfully exported this file " + "Eventually the actual data will be passed into this function" + ""); } private function login_result(event:ResultEvent):void{ if(event.result == true){ var request:URLRequest = new URLRequest("getExcelFile.cfm"); flash.net.navigateToURL(request, "_self"); } } private function serverFault( event:FaultEvent ):void { Alert.show( event.toString(), "Remote Object Fault" ); } ]]> </mx:Script> <!-- types of returns you can have from ColdFusion -> Flex, getAllAsStruct creates an array of structures to pass back with a special '__type__' struct key indicating to Flex what the type is. --> <mx:RemoteObject id="roWildcard" destination="ColdFusion" source="DeptApps.Statistics.Faye.stardust.cfc.CustomerGateway" showBusyCursor="true" result="resultHandler(event)" fault="faultHandler(event)"/> <!-- Make sure the Flex cffunction exportToExcel is available on the coldfustion component (DeptApps.Statistics.Faye.stardust.cfc.)Export.cfc --> <mx:RemoteObject id="exportManager" destination="ColdFusion" source="DeptApps.Statistics.Faye.stardust.cfc.Export" showBusyCursor="true"> <mx:method name="exportToExcel" result="login_result(event)" fault="serverFault(event)" /> </mx:RemoteObject> <mx:Panel title="{this.label}" width="100%" height="100%"> <mx:HBox> <mx:Button label="Call RemoteObject" click="buttonHandler()"/> <mx:Button label="Export" click="test()"/> </mx:HBox> <mx:DataGrid id="dg" dataProvider="{roResults}" width="100%" height="100%"/> </mx:Panel> </mx:Canvas> CustomerGateway.cfc <cfcomponent output="false"> <!--- Populating an array from a query, an array of CFML structures ---> <cffunction name="getAllAsStruct" output="false" access="remote" returntype="array"> <cfset var qRead=""> <cfset var aRead = []/> <cfset var sRead = {}/> <cfquery name="qRead" datasource="#application.dsn#"> select * from sav_customer </cfquery> <cfloop query="qRead"> <cfset sRead = {}/> <cfset sRead["__type__"] = "stardust.cfc.Contact"/> <cfset sRead["id_rssd"] = qRead.id_rssd/> <cfset sRead["ctct_id"] = qRead.ctct_id/> <cfset sRead["ser_id"] = qRead.ser_id/> <cfset sRead["inst_nm"] = qRead.inst_nm/> <cfset sRead["ctct_fst_nm"] = qRead.ctct_fst_nm/> <cfset sRead["ctct_lst_nm"] = qRead.ctct_lst_nm/> <cfset sRead["updt_dt"] = qRead.updt_dt/> <cfset arrayAppend(aRead, sRead)/> </cfloop> <cfreturn aRead> </cffunction> </cfcomponent> Export.cfc <cfcomponent> <cffunction name="exportToExcel" access="remote" returntype="boolean" output="true"> <cfargument name="data" type="string" required="yes" default="" /> <cfset session.exportData= #arguments.data#> <cflog text="data to be exported: #session.exportData#"/> <cfreturn true> </cffunction> </cfcomponent> getExcelFile.cfm <cfsetting enablecfoutputonly="true" showdebugoutput="No"> <cfheader name="Content-Disposition" value="attachment; filename=export.xls"/> <cfcontent type="application/vnd.ms-excel" reset="true"/> <cfscript> WriteOutput(session.exportData); </cfscript> <cfexit /> ====================== Code ends here I need to know how to set session.exportData to the return from CustomerGateway return method. Do I need to create another function? Thank you very much for your time.
