Quick Flash Remoting Fix (and simple Flex Sample) for Tartan Sample Application

The HelloWorld sample application that ships with Tartan has a small bug that might leave you scratching your head when you try to access them via Flash Remoting. It's a minor path issue which you can fix in two ways.

Taking the helloWorld example, either:
  1. Copy the config folder in tartanSamples\helloWorld to tartanSamples\helloWorld\remote, or

  2. Alter line 28 of tartanSamples\Application.cfc to read configFileLocation="#ExpandPath('../config/service.xml')#" (note the added "../" at the start of the path.)
Also, I don't believe that there are any Flash or Flex samples for using Tartan with Flash Remoting (it's actually dead simple) so here's the simplest possible Flex example:

MXML:
  1. <?xml version="1.0" encoding="utf-8"?>
  2. <mx:Application xmlns:mx="http://www.macromedia.com/2003/mxml" xmlns="*" load="initForm()">
  3.     
  4.     <mx:Button label="Get greeting" click="getGreeting()" />
  5.     <mx:Label id="status" />
  6.     
  7.     <mx:Script>
  8.     	<![CDATA[
  9.     	
  10. 			import mx.remoting.Service;
  11. 			import mx.remoting.PendingCall;
  12. 			import mx.rpc.RelayResponder;
  13. 			import mx.rpc.ResultEvent;
  14. 			import mx.rpc.FaultEvent;			
  15.  
  16. 			import mx.remoting.debug.NetDebug;
  17.  
  18. 			var helloWorldService:Service;
  19.  
  20. 			function initForm()
  21. 			{
  22. 	  			NetDebug.initialize();
  23. 		  	
  24. 		  		var gatewayURL:String = "http://localhost:8500/flashservices/gateway";
  25. 				
  26. 				helloWorldService = new Service ( gatewayURL, null, "tartanSamples.helloWorld.remote.HelloWorldFlashService", null, null );
  27. 				status.text="Initialized.";
  28. 			}    	
  29.  
  30. 			function getGreeting()
  31. 			{
  32. 				var pendingCall = helloWorldService.getGreeting ( "English" );
  33. 				pendingCall.responder = new RelayResponder(this, "onResult", "onStatus");
  34. 			}
  35. 			
  36. 			function onResult (resultObj:ResultEvent)
  37. 			{
  38. 				status.text = resultObj.result;
  39. 			}
  40. 			
  41. 			function onStatus ( faultObj:FaultEvent )
  42. 			{
  43. 				status.text = "There was an error getting the greeting.";
  44. 			}
  45.     	]]>
  46.     </mx:Script>
  47. </mx:Application>

I look forward to working with Tartan on our current Flex/CF project. We will be using it in conjunction with Model-Glue on the server side and, of course, Arp on the client :)
